The critical discourse approach as a emerging discourse trying to link between power and the dominant ideologies of actors in social contexts. Problematic settlements as a serious challenge to countries, have been hidden power relations objective experience of actors that the contribution of each of them in the production of these space have been different. therefore the purpose of  the present study is explain the effects of actors' activities on the production of the text of problematic urban settlements with  a critical discourse  and right-to-city approaches.

Research method of the present study in terms of  nature is qualitative and in terms of the type is analysis method.For explaining the text / space in problematic settlements was used a combination of qualitative-quantitative methods.Then the research variables were extracted and tested with Delphi technique that the 50 experts selected them.The effects of the indicators were evaluated by a one- sample t-test in Spss software and for the link the power and  ideology of  the actors was used in the production of text /space of problematic settlements with Mactor software.

According to experts idea, findings showed that  life experience of  residents in the form of concepts such as poverty, neglect, backwardness, invisible forces, conflict of interest, ambiguity in fate, distance between claim and action, distance between us and them, duality and conflict and personal interests not common good,  has found meaning. Concepts show the confrontation of government/urban management space strategies against the space tactics of weak people with naturalization of the dominant ideologies and the lack of awareness and economic weakness of the rsidents of these settlements. The role of middle management as a link between government and local management have been significant in the production of text / space of  problematic settlements.

 recognizing the rights of the users of  these settlements with decryption of  hidden meaning  behind the apparent meaning, it can be increased the conditions of domination of the main actors at different levels in the form of self-Administered and self-management.

The phenomenon of Thermal Island as one of the urban hazards is the result of the way of activity and physical development of cities as well as extensive changes in the land use pattern around cities. The surface temperature of the earth is not only affected by the amount of energy received by the sun, but also by the environmental conditions of the place, especially the reduction of suburban arable land, vegetation degradation and increasing impermeability levels and potentially prone to heat production and pollution. Heated island is a term used to describe the warmer atmosphere and higher temperatures of cities compared to non-urban areas. Determining the geographical distribution and nature of UHI, as well as the factors influencing its occurrence or severity, is something that is now efficient, fast, and inexpensive using satellite imagery and remote sensing techniques. Ahvaz is one of the metropolises with ethnic diversity and mixed subcultures that has experienced a large and rapid increase in population and area over the last three decades and the city has expanded in different directions from south to southwest and north to northeast Has found. One of the prominent consequences of this issue is the emergence and strengthening of the Heated island in this city.

To determine the spatial-place changes of the heated islands of Ahvaz and also to determine its relationship with land use changes, first the Landsat satellite TM sensor images in the last 30 days and Envi software were used and the following main steps were performed:Stage 1 - Preparation of thermal map of the city: To calculate the temperature of the single channel algorithm (SCA) in order to extract LST, an extended infrared thermal band was used and to calculate it, Equation 1 was used. Ts = γ {𝜀1- (YLsensor + Ψ2) + Ψ3} + δ Here are five essential steps you can take to begin the process of preparation for mediation. To calculate each of the parameters in the equation below 5 consecutive steps as described in the headings The first step is to calculate the spectral radius The second step is to calculate the light temperature of the sensor The third step is to calculate the radiative power Step 4, calculate the values of γ and δ Step 5, calculate atmospheric parameters Stage 2: Prepare a land use map using the decision tree: The function of the model is a branch that consists of three levels of decision making and finally to determine the six layers of land cover (including agricultural land, rangeland, irrigated land, heights (Topography), land with little vegetation and built-up lands. In the model run, after applying the preprocessors to the Landsat images, the corresponding images were created for classification using NDVI, DEM, NDWI and LST indices. Setting a threshold for the NDNI index (NDVI> 0.26) vegetation is isolated from other data. In the correct branch, the next node was isolated using NDWI index (NDWI≤0.0) and determination of rangeland class threshold, agricultural land and water. In the third decision-making branch, based on the thresholds defined in the image indices (DEM≥40), DEM topography was determined, Were introduced.

Statistical study of the trend of change in land surface temperature and construction index and the ratio of change of other carabis to urban land uses showed that the trend of change is the average construction of the ascending course and the average temperature of the ascending course and the trend of changes with the transformation process With the expansion of the city of Ahvaz, their vegetation and land have been destroyed and turned into urban lands, and now the thermal island has been directed from the inside of the city to the outskirts. The temperature increase ratio of the urban area was higher than the whole study area.

Based on the results, the temperature of Ahvaz city increased from 282.96 degrees to 287.02 degrees Kelvin between 1988, which shows a growth of 2% and an increase of 4 degrees. Spatially, the highest temperature increase in the city is related to the east and southeast of the city, where agricultural lands and lands with little vegetation have been converted to industrial town and industrial uses and become a source of heat production in this metropolis. Has been. Also in the western part of the city, due to the further expansion of the city and the implementation of residential preparation projects - the NDBI index confirms the same - there has been an increase in temperature. Other influential factors in the spatial change of temperature in these parts of Ahvaz city are the existence of main roads such as Ahvaz-Abadan highway (southern part of the city), Ahvaz-Bandar Imam Khomeini highway (eastern part). Due to the asphalt cover of these routes and more vehicle traffic, they have caused an increase in the thermal map of the region. The lowest temperature in 2020 is related to the areas around the Karun River. Among the factors that have caused the low temperature in this place compared to other parts of Ahvaz in 2020, we can see the existence of the government park, Shahid Chamran University with a lot of green space and low-density residential texture and more open and green space than they  mentioned other parts of the city as well as the wetlands of the last two years. Analysis of the trend of UHI changes and increase in construction using Landsat time series images showed an increase in urban temperature compared to the surrounding area in 1988. This shift in 2020 was due to an increase in regional temperature compared to the city due to river flooding. , Increase in construction and industrial activities in and around the city. Due to the environmental dangers of the Heated island, which directly and indirectly affect urban air pollution, greenhouse gas emissions and global warming, disrupt thermal comfort, increase water and electricity consumption, and exacerbate diseases such as asthma They leave, It is necessary to prevent the change of agricultural use to urban areas, and within the city, between dense textures and industrial areas, by creating vegetation in the form of parks and gardens, tried to prevent the rise in surface temperature.

Urban branding is a well- meaning concept with at the same time as the globalization approach and has increased competitiveness between cities at national and international levels. Place branding is a strategic tool and method about sharing a competitive advantage and the city index to be on the path to future development. The most important principle in urban branding is to highlight the historical values, natural beauties, cultural, economic and social infrastructure of cities. Conscious branding gives cities a new identity. In the modern age of globalization of symbols and places, cities make efforts to describe their distinctive feature. In addition to the factors of urban economy and development of urban infrastructure, factors such as: quality of life of citizens, urban aesthetics and planning for local development are among the development criteria. Brand City is a placeholder image and package that emphasizes the unique features of the city; So that the city can be ahead of other competitors in the competition. but this does not seem to be a new phenomenon, and historical cities in Iran have always tried to traditionally use the capacity of the titles to advance their own goals.

The hypothesis in this study is: "assigning titles to ancient Iranian cities in previous periods has had a similar effect and effect, such as the concept of place branding in the urban structure". The method of the research, the historical-interpretive research method and the information gathering tool were library, documentary and based on content analysis and historical texts. For a closer examination of the subject, the city of Tabriz with the title of Dar-ol-saltaneh's in the Qajar period was selected which this title turned Tabriz city to a place for crown prince and Tabriz got a better political position after Tehran.

Tabriz political Importance along with the Spatial-Geographical Importance of the city, due to the East-West trade route, Dar-ol-saltaneh of Tabriz, was turned the gateway to the arrival of modernity and communication with the overseas. In order to evaluate the research hypothesis, at first studied the place branding, the components and the criteria for evaluating its effects in the city and in the following, a case study has been reviewed and evaluated. A case study analysis was in the form of place branding components, it should be extracted from the theoretical framework of the research. The components of location branding in the present research model include four axes: Imagery, Identity and Related Issues, Environmental Qualities, especially Urban Qualities, and finally Socio-Cultural Issues. The imagery component focuses on information and advertising around the site in question. The identity component in the urban context address issues arising from the context and affecting identity. In this component, special emphasis is given to the particular distinction that exists in place and which forms part of the identity of the people and the identity of the place. The component of environmental quality, especially urban quality, studies the physical characteristics and physical elements that influence the structure of the city. Finally, the component examines socio-cultural issues, cultural and social contexts, special events and events, and seeks to promote and present them as an important and influential component.

It is imperative to point out that all of these components do not require at first; urban branding is a time-consuming process that begins with a set of capacities and potentials in the context of the study, and over time other values and components are added to it. The results of the research show that in the historical cities of Iran, got a title has the similar effects to the Iranian cities with the place branding effect and and show the validity of the research hypothesis. Increasing the environmental qualities, especially urban qualities in the city of Tabriz, establishing socio-cultural issues and the manifestation of these developments in the late Qajar, improving the quality of mental image of individuals and identity in the Qajar period and finally desirable illustrations of the Qajar city of Tabriz in documents Foreign and Iranian are among the important events and developments. In other words; Dar Al-Saltanah brand in the Qajar period in the city of Tabriz caused significant changes and changes that the environmental qualities, socio-cultural issues, identity and imagery in this city grew and developed.

Morphological Assessment will be necessary to understand the current situation and the potential for possible river changes in the future. Natural factors such as floods, soil erosion, landslides and human factors such as land use change and sand removal from the riverbed affect the morphology. River systems have always been of interest to humans as one of the most vital elements of the Earth's surface. Humans also change the face of the earth by changing their use, destroying natural resources, plowing the land in the direction of the slope, planting trees in the riverbeds. Any Manipulation into the riverbed will change the process of erosion and sedimentation along the river. Understanding the characteristics of flow and sediment is the basis for evaluating the behavior of rivers and deciding on engineering activities. Therefore, it is necessary to obtain the necessary information on how they work before starting engineering projects for rivers.

In this study, geological maps at a scale of 1: 100000 of the Geological Organization, topographic maps at a scale of 1: 50,000 digits of the Geographical Organization of the Armed Forces, Landsat satellite images, 2020 April, November 1995, Climatic data Temperature and precipitation (1399-1374) of Lorestan Meteorological Organization and Digital elevation model of 30 meters has been used. Arc GIS software was used for spatial analysis and ENVI software was used for processing satellite images. The normalized water difference index is the first index of water extraction in images and remote sensing data. In this indicator, two green and infrared bands are used. Positive values of this index indicate water and negative values indicate phenomena other than water. Researchers have proposed different methods for studying changes in river channels. The transect method is used to evaluate changes and displacements in river channels. In this method, lines with specific distances on both sides of the river route are drawn as baselines. These lines are constant for the time periods studied. River channel displacements relative to these lines are quantified. To further evaluate the Kahman River canal, the canal migration rate method was used. The Kahman river Canal was divided into two areas, mountainous areas and plain and agricultural areas, based on topography and land use.

To calculate the area to the right and left of the transects, the Kahman river channel was cut separately with a transect layer in 1995 and 2020. Calculation of changes in the area of transects shows that about 185.85 hectares of land adjacent to the Kahman river (1995-1999) have been eroded. On average, about 7.43 hectares of these lands have been destroyed annually. The maximum value of this index in transect 30 is calculated at 8.27 hectares. In order to better understand the changes and dynamics of the Kahman river Canal, the migration rate index (Rm) was also used. First, two fixed lines were drawn around the Kahman river channel. The area between the two was calculated using Arc GIS software functions. The average migration rate of Kahman river (1399-1374) was 2.51 meters per year. The lowest level of this index occurred in Trasket 49 at 0.18 meters per year. The mountain factor and stabilization operations along the river have been the most important reasons for its control and stabilization. The highest rate of migration occurred in transects 4, 32 and 30 at 4.80, 5.5 and 6.12, respectively. Shortcuts and land use changes have been the main reasons for the high rate of duct migration in these transects. The largest amount of lateral changes in the Kahman river route occurred in parts of the plain and agricultural areas, including transects 30 to 35. The most important factor was the high lateral changes of the Kahman river route in the plain area due to the high erosion of the coastal and floodplain materials. Most of the constituents of the bed and banks of the Kahman river in these periods are from fine to coarse sands.

Duct migration rate index showed that the average displacement of Kahman river canal (1374-1399) was 2.51 meters per year. The lowest value of this index was 0.18 meters per year and the maximum value was 6.12 meters per year. Calculation of changes in the area of transects showed that about 185.85 hectares of land adjacent to the Kahman River (1374-1399) has been destroyed. On average, about 7.43 hectares of these lands are lost every year. In the mountainous area, the effects of the mountains were the most important factor in determining the morphological changes of the Kahman River channel. The presence of erodible materials along the Kahman River in the plains and agricultural areas has increased the lateral migration of meanders and the width of the valley and floodplains adjacent to the river has increased significantly. Therefore, it can be said that the Kahman River has had more geometric changes in the plains and agricultural lands.

The emergence of the mechanized phenomenon increased the human’s need for nature and using it in a peaceful environment so that the natural environments can be established to link nature to the city and create public and popular spaces to link the human to nature. Therefore, some measures must be taken to improve the quality of the roads besides creating them to increase the walkability (Sharghi et al., 2017; Najafpour et al., 2014). Qazvin Health Road, located in the northern part of the city, was created to have a healthy society. However, it did not reach its highest level in terms of facilities and quality.  The current research aims to evaluate the factors affecting the desirability of the urban pedestrian zones with an emphasis on the Qazvin Health Pedestrian Road through which the more presences of the people to improve the health level of the society in the urban and natural spaces is provided by recognizing the factors affecting their quality and improvement in this road. This plan is a dynamic process that was implemented to provide the mental and physical health of the people and increase their happiness and pleasure from the opposite of Islamic Azad University, Qazvin Branch, to Barajin Park.

The current method used a questionnaire to collect the data as one of the most common tools in field studies. Cronbach’s alpha method was also used in confirming reliability, which is considered as the most practical and significant method to measure the reliability. If this value is higher than 0.7, it can be said that the tool has higher reliability (Siamak & Davarpanah, 2009). 30 primary questionnaires were distributed among the members of the statistical population to evaluate the validity, and as a result, the criteria with Cronbach’s alpha less than 0.7 were eliminated, and the criteria with a coefficient higher than 0.7 were obtained as the final questionnaire. Then, given determining the sample size obtained from Cochran’s formula, 400 questionnaires were filled. The data and the items of the questionnaire were first coded using SPSS software to analyze the data obtained from the questionnaire, and then, the related values were typed in their specific order. In the following, the Kolmogorov-Smirnov test was used to study the normality or abnormality of the data distribution, and the results indicated that the distribution of the data was abnormal. Therefore, the Binomial test was selected as the analysis method, which is a non-parametric test, in proportion to the research purpose.

The research results indicate that the following criteria gained the maximum satisfaction of the residents: in physical factors, connectivity and the width of the axis, in environmental factor, the cleanness and hygiene; in comfort and convenience factor, the lack of noise pollution and the status of the flooring; in the physical and activity factor, the criterion of various usability of the path. In contrast, the following factors obtained the least satisfaction: landscaping in the physical factor, protecting the pedestrian against climate changes in the environmental factors, the facilitation in the comfort and convenience factor, and functional diversity in the physical and activity factor. As presented, paying attention to the four mentioned criteria has the maximum effect on the desirability while Siadati and Karimifard (2018) considered vitality the most effective criterion in increasing the desirability of the pedestrian axes. Similar to Hajrezaei (2019), the land use and activity along with the mixed land uses, functional diversity, and various usability of the path are among the factors that have the most effect on the desirability of the pedestrian axis in the current study. Furthermore, in a paper conducted by Punter and Carmona (1997), the environmental factor and the quality of the public area were considered significant. In a study by Habibi and Sheikhahmadi (2019), increasing the legibility using urban landmarks, land use diversity, and physical diversity, safety, and security, using natural elements, and the connectivity of the path are the factors that lead to increasing the desirability. Seyfallahi Fakhr et al. (2013) believe that the function has the most effect on creating a safe pedestrian path, resulting in increasing the desirability of the axis, which was also mentioned in the current study.

The current research aimed to evaluate the factors affecting the desirability of the urban pedestrian axes in Qazvin Health Road as a case study. After reviewing theoretical foundations and surveying the experts, the factors were selected as the main factors in the desirability of the urban pedestrian axes that are as follows: physical factors, environmental factors, comfort and convenience, physical and activity status of the Health Road. Then, through observation and field studies, a questionnaire was developed and distributed among them to investigate the desirability of the pedestrian axis. In the following, after collecting the questionnaires, citizens’ satisfaction with each one of the criteria were evaluated using the Binomial test. The research results indicate that the following criteria gained the maximum satisfaction of the residents: in physical factors, connectivity and the width of the axis, in environmental factor, the cleanness, and hygiene; in comfort and convenience factor, the lack of noise pollution and the status of the flooring; in the physical and activity factor, the criterion of various usability of the path. In contrast, the following factors obtained the least satisfaction: landscaping in the physical factor, protecting the pedestrian against climate changes in the environmental factors, the facilitation in the comfort and convenience factor, and functional diversity in the physical and activity factor. In the end, it is noteworthy that the research results and the recommendations that were determined based thereon can be considered by all the executive organizations, and finally, result in improving the quality of this road and the similar examples in Iran.

With the advent of modernity and modernity, the urban body witnessed the bitter experience of failed modernization. This failure was especially evident in Third World cities and led to a decline in human quality of life in various economic, social, cultural and aesthetic dimensions.

The present study challenges the effects of the growing trend of various types of urban renewal in the social dimension, as the most prominent form of human life in dealing with human affairs is the "city"; Thus, the city's reputation may be honored or shattered by human norms or anomalies. Urban spaces affected by anthropogenic anomalies are often trapped in an uncivilized spirit in the body of civilization. Thus, the Renaissance in urban spaces, especially the streets, which is the most important arena of citizenship, seeks to eliminate the anomalies of unfinished modernism that dominate public spaces by producing human-based civil spaces.

In fact, street renaissance is a response to how social relationships are discovered, strengthened and revealed in one of the most important behavioral centers of the city, which as a strategic tool is able to produce and reproduce social spaces in the city. Considering that Sabzeh-e-Meidan, as one of the main bases of Zanjan city, has been affected by unthinkable modernization, the revival and production of human spaces in addition to commercial spaces seems inevitable.

This study is based on the idea of ​​producing a qualitative analytical Lefebvre space in order to acknowledge the impact of social indicators on the central part of the city (Sabzeh-Meidan), which finally confirms the existence of potential social potentials in the area by providing a qualitative model with Maxqda software.

Extraction and processing of various features with the help of aerial imagery reduces the time and financial costs associated with the use of ground mapping and the resulting human error. Advances in the field of aerial sensors in terms of spatial and spectral resolution with precise place and performance picking up altitude from the ground have led to the use of each part of information about terrestrial phenomena such as spectral and spatial characteristics Brought. Today, complementary data used to detect complications are Lidar data, the sensor of which is sent and received, and the electromagnetic spectrum in the near-infrared spectrum (in its aerial form) and joined the spectrum. Pays close infrared and green band (in space type).

Lidar data and spectral images were analyzed using different types of algorithms effective in landfill extraction to assess density. New layers of images were obtained in the form of raster from the study area, which was analyzed by performing slope extraction steps on flat and sloping surfaces. Buildings that were definitely not buildings were removed. The size and spectral characteristics of the missing structures were identified and the parcels were redistributed to extract the impermeable surfaces. Which led to the achievement of two levels of parcels and impenetrable points. The data set is related to the northern part of Bandar Anzali, which includes a vertical aerial photograph, irregular cloud points of the region with dense one to two points per square meter with an average point space of 0.69 square meters, and vertical aerial photograph with spatial resolution. It is 8 cm square.

In this study, a different method for extracting buildings using airborne Lidar data and ultracam images was presented. The proposed system used geometric and spatial information of Lidar data and ultracam images, which included three general steps, in the first step; Lidar data were filtered and extracted using spectral clustering of buildings. In the second step; The obtained model was compared with the two-dimensional boundaries of buildings by the height threshold method. In the third step; After extraction, the first building boundaries were merged with the structures extracted by the checker algorithm. In the stage of separating terrestrial from non-terrestrial points, all points related to land were classified and extracted. The remaining points were classified as roof points, which were dealt with in the fault section of the buildings. All the functions used enabled the system to successfully extract the structures from the Lidar data.

The data for the first return points were subtracted from the data for the last return points and a fixed value was obtained which depended on the altitude accuracy of the difference between the two returns. In addition to the mentioned method, the clustering method was used during the research that each cluster belonged to a roof section so that the characteristics of each surface model could be easily determined.
Then, to complete the shape of the roof, the footprint of the building that was extracted was used. In fact, the borderlines and inner vertices extracted only part of the shape of the border. Other sections, such as vertical edges, were not detected due to intersection. This is due to the lack of front sampling. Finally, the items extracted through spectral clustering in eCoginition software and two-dimensional boundaries extracted from ENVI Lidar software, to increase the accuracy of land surface extraction (buildings) and make the area of ​​buildings studied in this data Were merged. As mentioned; After extraction, the primary building boundaries were merged with the structures extracted by the checker algorithm. In the section of buildings diagnostics, buildings with errors were discussed and the evaluation of the results showed that the system used has relatively reached the set goals and the methods used include the threshold method. Elevation, clustering, spectral method, and integration method were evaluated for each of the four blocks with error rates of 28%, 15%, and 0%, respectively, based on the area of ​​extracted tolls to the study area. The error of each building was first examined in general and then in detail, and it was found that aerial Lidar technology has an extraordinary ability to collect very right and dense samples of altitude measurements of cities and a new level of detail information can be Accurately extracted building density automatically and efficiently from aerial Lidar data. In 417 buildings that were surveyed and analyzed, the height of the buildings was achieved with high accuracy and all the buildings in the study area were extracted with a compact and organic density as well as scattered and planned.

Over the last few decades, natural disasters and their aftermath have become a major concern for leaders and organizations around the world. Vulnerability is the "characteristics of an individual, group or system and their situation that affect their ability to anticipate, cope with, resist and recover from natural hazards." Physical vulnerability is: "The probability (or potential) of being affected or damaged by a specific physical component or element under the influence of a particular external driving force, for example a natural hazard such as an earthquake. Today, physical vulnerability is a component. The main key elements are used as model input data by organizations in charge of risk prevention and mitigation, and the development of building codes and guidelines. A look at the seismic history of Iranian cities in less than a hundred years, the widespread vulnerability of Iranian cities to this natural disaster is evident, of course, among the concerns of residents of dilapidated cities. It will be far more than others. The main goal of the action plan is to provide a rapid and effective response that minimizes potential damage to people, property and the environment, and returns basic services to people in the shortest possible time.

In this study, a method based on the vulnerability index has been used to assess the expected damage in Ardabil. Risk analysis for seismic scenarios defined by seismic intensities V, V-VI, VI, VI-VII and VII has been performed to design seismic emergency plans. This method uses the mean of quasi-experimental vulnerability functions, which for a given vulnerability index is strongly related to the seismicity and the expected damage. According to the country's seismic Codes, the basic peak ground acceleration for a 475-year return period is 0.04g, which corresponds to an intensity of VII. Thus, while quantifying physical damage, its impact on the population and other amounts such as debris and economic costs have been investigated.

Vulnerability of buildings in Ardabil shows an average value of 0.59 for concrete buildings and 0.93 for buildings with building materials, which are the most vulnerable. Therefore, it is predicted that buildings with building materials that belong to worn-out structures will have a higher degree of damage. The distribution of highly vulnerable neighborhoods is seen in the central core of the city. The vulnerability index of areas 1 and 3 is higher than other areas. For the seismic scenario VII, the degree of vulnerability of these textures is heavy, very heavy and completely devastated. In the worst-case scenario, about three in a thousand people die of decayed textures, and not every thousand people suffer various injuries. An earthquake with a intensity of V-VI will cost approximately 98 million Rials and a intensity VII equal to 6800 million Rials for these textures. Due to the impact of a seismic crisis on narrow and uneven communication passages and arteries, there is a significant volume of expected debris production among the eroded neighborhoods (for scenarios V-VI and VII, respectively, between 1701 up to 13989 tons). Due to the combined effects of the large volume of debris produced and the urban pattern of narrow and irregular passages, any movement will face several problems. In the seismic scenario with intensity V-VI, 332 people from the population of     decayed textures and in the scenario with intensity VII, 3224 people from the population of textures these become homeless. Therefore, the only way to reduce seismic risk with a vulnerability reduction approach is to apply seismic instructions and increase public awareness of these issues.

The city of Ardabil is in the range of moderate to high seismic hazard, which is mainly due to the large accumulation of population and old and vulnerable buildings. Vulnerability of residential buildings is high, mainly due to their age and lack of knowledge and awareness of seismic hazard and in terms of seismic actions expected in the design and construction of buildings. This high vulnerability causes significant direct physical damage to buildings, especially worn-out structures, even for low-intensity earthquakes. As a result, the expected physical damage in the case of moderate earthquakes is significant. For a intensity V earthquake, the damage is not expected to be significant, but for a intensity VII scenario, all five areas and the dilapidated tissues within them will experience a level of damage that is slightly higher. Damage is 2 (moderate). In addition to the significant number of casualties, emergency management after the earthquake and subsequent recovery of normal city activities in the medium and long term is important.

The metropolis of Tabriz is considered as one of the mother cities of Iran and the most populous city of East Azerbaijan province and the center of administrative and political services to the northwest of the country. For more than 100 years, this metropolis has always been one of the economic hubs of Iran and has been one of the gateways to Iran and the arrival of technology and social developments in Iran. The special position of this city has led to its rapid and unbridled growth. The economic and industrial position of this city has always welcomed a wide range of rural and urban immigrants from different parts of Iran. Immigration of this city has led to insufficient urban services, formation of informal neighborhoods, occurrence of social anomalies, urban traffic, air pollution, social inequality, inefficiency of urban management and so on. Therefore, the city of Tabriz, due to its population in recent decades, has faced the problem of injustice in the distribution of municipal services. Considering the importance of studying this issue, it can be said that the main purpose of this study is to find a scientific answer to the question of what is the quality of citizens' access to public uses in the city of Tabriz? What is the situation of different areas of the city in terms of the studied indicators? And finally, what are the practical suggestions for improving the current situation of Tabriz in the field of improving social justice?

This research is based on the applied purpose and based on the descriptive-analytical nature, the required information has been obtained in the form of library and field. The reference for collecting the information required for this research through a comprehensive and detailed plan of the city of Tabriz, was the preparation of a special questionnaire to collect information from relevant institutions (municipality, cultural heritage, health network, education, etc.). In order to grade the levels of spatial justice, 9 variables of cultural-artistic, educational, administrative-disciplinary, medical, park and green space, religious, urban equipment and urban facilities have been used. To do this, the weight of each criterion has been determined using Shannon entropy method and to analyze the data, multi-criteria decision making method of Vicor, TOPSIS, Prometheus and integration model (Copeland) has been used. Also, GIS v10.5 software has been used to draw a spatial map related to the prioritization of urban areas of Tabriz in terms of the studied indicators.

As the results of the research showed using the three models of Vicor, Topsis and Prometheus, the prioritization of the ten districts of Tabriz in terms of the nine criteria of social justice, had different priorities. Therefore, in order to integrate the results and provide the final prioritization, the Copeland integration model was used. In the Copeland method to classify the areas of Tabriz city, the numerical range of 9 and 9 (6 to 9 is highly enjoyed, 3 to 6 is enjoyed, 3 to 3- is relatively enjoyed, 3- to 6- is relatively deprived and 6- to 6- is deprived) is used. It becomes. The results of Copeland method, which is obtained by combining the results of three models of Vicor, Topsis and Prometheus, show that areas 6 and 8 of Tabriz metropolis are in a very good position in terms of spatial justice. Zone 3 is in a privileged state, Zones 2, 7, 10 and 1 are in a relatively prosperous state, Zone 5 is in a relatively deprived state and Zone 9 is in a deprived state.

In general, it can be said that in terms of priority of Tabriz urban areas in terms of social justice criteria, economic and commercial factors are more effective and have a greater role than other components. And the more financial institutions, the higher the score compared to other regions.It should be noted that in this study and other similar studies, access to urban public services and social justice has been examined from a quantitative approach without regard to its quality, while in the field of social justice, the quality of uses as well as The quality of access to public services is more important than its quantity, so it is suggested that in future research, the issue of social justice be considered from a quality approach.

Sustainable livelihood approach is one of the new approaches in sustainable rural development that has been considered to reduce poverty and rural development. This approach focuses on the diversity and increase of various rural activities and emphasizes the diversity and increase of various rural activities. Sustaining the sustainable livelihood of the villagers in today's world is one of the priorities that should use the various assets (natural, human, financial, physical and social) of the villagers to improve and enhance their livelihood. The general purpose of this study is to evaluate the living conditions of rural communities in Darrehshahr city using SLF approach and CIPP model. Took. The total size of the statistical population was 16.140 households and the sample size was determined using Cochran's formula of 380 people.To analyze the data, descriptive and inferential statistical methods were used using SPSS software. The obtained results show that there is a significant difference between the studied villages in terms of livelihood assets. Friedman test also shows that the share of natural assets is higher in the studied villages and the share of human, social, natural, physical and financial assets is 3.39, 3.30, 3.59, 1.33, 3.39, respectively.

The present research is non-experimental in terms of application type, non-experimental in terms of data collection and survey type. The statistical population of the study includes 16140 rural households living in Darhshahr city, which has a population of about 58429. The sample size was obtained based on Cochran's formula of 380 households. The data collection tool in this study is a structured and researcher-made questionnaire. SPSS software was used to analyze the data. The collection tools in this research include library and field methods. The validity of the questionnaire was confirmed using a panel of experts, and for the reliability of Cronbach's alpha used, its total value (0.73) was obtained. The independent variables of this research include five variables (human, physical, social, natural and financial) and the dependent variable is sustainable livelihood. The following hypotheses have been used in this study.

The results show that among 380 respondents, 60.86% were men and 90.12% were women, of which 2.14% were literate, 17.4% were middle school students, 9.33% were diploma students, and 6.6% were graduates. , 14.2% were associates and 6.6% were bachelors and above. Also, 3.70% were self-employed, 3.19% were government employees, 8.5% were retired, 1.8% were unemployed and 9.2% were students.

Regarding physical capital, the findings showed that the situation of marketing of agricultural products and products and the infrastructure of agricultural activities is very weak, while the main livelihood of the villages under study is provided by agriculture.Regarding the natural factors, the findings showed that the recent droughts have had the greatest impact on the living conditions of the studied villages, which is consistent with the results of Bazrafshan et al. 1397 and Darban Astana et al., 1397.Regarding financial factors, the findings showed that fluctuations related to agricultural products have a great impact on people's lives. Also, the findings showed that investment to create employment by the government and the willingness of the private sector to invest in the villages studied is very low It is very high, which is consistent with the results of research by Weiss et al., 2017 Regarding humanities, the findings showed that the level of access to educational services on livelihood and employment issues, unemployment rate at different ages and the status of courses and educational programs related to livelihood is very low. Which is in accordance with the results of Jamehpour and Ahmadi research, 2011. Also, the spirit of cooperation and cooperation and family relations among the residents of the studied villages is high in terms of livelihood activities, which is consistent with the results of Bazrafshan et al. 1397.Regarding social factors, the findings showed that the tendency of villagers to urban life and the departure of labor and youth migration to urban areas is very high, which contradicts the results of research by Jomehpour and Ahmadi, 2011. Also, the level of use of media and social networks is very low.

 The trend of urban change and subsequent changes in the ecological structure of Behshahr city during the last 34 years has caused many environmental problems. So that the horizontal expansion of the city to the four directions and consequently the increase of ecological footprint in this city has led to many changes in use, especially from agriculture and gardens within the city limits to residential and commercial, etc., which causes The destruction of the ecological foundations of the urban environment, the reduction of the capacity to absorb pollution and the intensification of pollution, the lack of green spaces compared to the built-up urban spaces, and finally the reduction of environmental resilience in this city. Accordingly, the purpose of this study is to investigate the trend of changes in the extent and structural pattern of urban land cover based on Explanation of urban ecology structure during the last 34 years using remote sensing techniques and landscape metrics.

 The research method in the present study is analytical-descriptive. The data and information required for the research have been collected and processed through library and field studies. In order to identify and create land use maps and with the aim of examining the structural elements of Behshahr city, the images of TM and OLI sensors of Landsat 5 and 8 satellites related to June in two time periods (1986 and 2020) from the US Geological Survey ( USGS) was used. Also for combining bands, processing and classification of satellite images from ENVI 5.3 software, for measuring landscape metrics from Fragstats4.2.1 software, for preparing maps and data of other software, from Arc Gis10.7 software And Arcview3.2 and Excel software has been used to sort the data and prepare the charts.Finally, using appropriate landscape metrics at two levels (class and landscape) including metrics, MNN, LSI, MSI, MPS, ED, LPI, NP, PLAND, CA Cohesion, changes in the ecological structure of Behshahr were evaluated.

 In this study, after processing the Landsat satellite images of the studied years (1986 and 2020), land use was classified into four classes: built-up lands, barren and gardens, and green spaces and agricultural lands.According to the results obtained from land use changes, in 1986, lands built have the highest percentage of area, ie 470 hectares (38.5%) among land uses, and respectively agricultural lands, green space and barren in the next ranks. In 2020, the built-up land has grown significantly compared to 1986 and has reached 788 hectares (65%), and other uses, agriculture, green space and wasteland are in the next categories.Also, the analysis of Behshahr Landscape metrics during the last 34 years shows that the metric value of the number of patches (NP) has increased from 599 in 1986 to 863 in 2020. In fact, the decrease in their number indicates fragmentation and The fragmentation of large agricultural spots, green spaces and gardens in the study area is due to the increase in urban construction. This reduces their sustainability and ecological performance. The average patches size (MPS) also shows a decreasing trend and has been reduced from 1.96 in 1986 to 1.43. In general, metric changes in the average patches size indicate an increase in degradation and thus a decrease in ecological resources in the study area.The results of the research also show the fact that the metric value of the average distance of the nearest neighbor (MNN) of Behshahr landscape has increased in the last 34 years and has increased from 79.01 meters in 1986 to 84.69 meters in 2020. This justifies the reduction of connection and continuity of land use patches, especially agricultural lands, gardens and green space.

In general, one of the obvious results of examining the changes in land use maps of the two periods is as follows: Land use made in this period due to increasing population and demand for land and, consequently, urban growth in recent decades, with the most Area changes have increased and increased by (68%). But other land uses have been declining, so that ecological and green lands, agricultural lands (-52%) and gardens and green spaces (-31%). ) And barren lands have also decreased by about -41%.The analysis of land landscape metrics also clearly shows the effects of human activities and urbanization on the environment, and the results indicate that the landscape of Behshahr city has become more complex, more geometrically complex andgeometrically irregular, and with decreasing continuity, It has become more fragmented. In fact, the results of Cohesion, MNN, LSI, MSI, MPS, ED, LPI, NP, PLAND, CA metric analysis show that the studied land uses, especially agricultural lands, gardens and green space in Behshahr in terms of composition and distribution. The space does not have favorable conditions and during the period under study in terms of extent, continuity and nature of the composition and distribution of ecological patches, especially agricultural patches, has undergone a process of severe destruction. So that, changes in the amount of NP (number of patches) and MPS (average patches size) have been indicators of the formation of a downward trend and ultimately the destruction of the system, indicating that reducing the average size of patches, the destruction process in The system shows and in fact a genuine integrated patch has become a number of small patches and has lost its cohesion.Also, the results of the study of land use continuity metrics (MNN and Choesion) show that in the mosaic network of urban ecological patches, especially agricultural lands, gardens and green space, while eliminating a large part of these patches and changing its use. On the one hand, the average distance between similar patches has increased over the last 34 years, and on the other hand, they do not have the necessary area.continuity and integration to provide ecological services to improve the environmental quality of Behshahr.

Due to the need to provide housing in different countries, governments have taken comprehensive measures and planning to provide housing for different groups, especially the low-income classes. But the reality is that the methods of planning and intervention in housing production, land supply, and established urban standards have been inefficient and have not benefited the lowest-income groups. On the other hand, policies that emphasize the construction of housing for the low-income classes have paid little attention to its environmental effects. It is also important to note that the challenge of providing housing for low-income urban groups in developing countries is not limited to housing alone. Lack of living space and interior spaces of the house and inefficiency of heating and cooling facilities, insecurity against natural hazards, are among the most important issues that are not considered and studied when providing housing policies for these groups. To take. On the other hand, according to experts, housing programs for low-income groups have been the only housing for swollen housing wounds among these income groups; A large number of households in the conditions of homelessness, housing shortage and poor housing, show a lack of macro vision of this sector and the ineffectiveness of policies implemented in the housing sector and solving its problem in the country. For a variety of reasons, these policies have always faced serious challenges from the public and critics, as managers and planners in the field are now convinced that many policies and Investments in the housing sector may improve temporarily in this sector, but it will not be a way to achieve safe and sustainable conditions. What is needed is a rethinking of macro-management approaches and the use of new tools in planning, tools that make sense of the third wave of management (change to adapt to the future environment). In this regard, this study intends to identify and investigate the most important factors affecting the provision of adequate housing for low-income urban groups in the city of Tabriz.

The present study, with a futures research approach, identifies the most important factors affecting the housing of low-income groups in the city of Tabriz and examines the extent and how these factors affect. This research is applied in terms of purpose and according to the components under study, the approach is the descriptive-analytical method. Environmental and Delphi scanning techniques have been used to identify variables and indicators. In this regard, in the first stage, to collect variables from online articles, a review of published articles on the factors affecting the provision of housing for low-income groups was used; Then, a semi-structured questionnaire was distributed between experts in the field of urban issues and they were asked to score points in the matrix of intersecting effects on variables, based on effectiveness and influence with numbers in the range 0 to 3. In this rating, "zero" means no effect, "one" means weak effect, "two" means medium effect and "three" means high effect. The scores were then entered in a cross-matrix to measure the direct and indirect impact of each factor and to obtain key drivers according to the scores of the factors. In scenario-based studies, the expertise and knowledge of experts take precedence over the overall quantity and the sample size should not be less than 25 people. In this study, in order to consciously select the participants, purposive sampling method has been used. The basis for using purposive sampling method is to select a group of experts who have an in-depth study or general understanding of the nature of the research questionnaire. Based on the above explanations, the statistical population of this study is 50 experts in the field of urban issues, including experts of Tabriz metropolitan municipality, consulting engineers and some university professors specializing in the field of study.

Based on the rank obtained from key factors, 16 factors were identified as drivers in low-income housing planning in Tabriz. These drivers are in order of importance: per capita construction credits (government development credits in the housing sector), security against earthquakes and natural disasters, housing prices, the quality of urban space, the level of security against urban crime, how to access Educational centers, access to cultural and recreational centers, access to health centers, urban green space, quality of design and construction, access to public transportation, cost of urban infrastructure, access to water, electricity, gas, telephone, sewage, residential density and Construction cost.

Given the obtained key drivers, it can be acknowledged that success in achieving comprehensive goals in this field depends on continuous interaction between key factors and careful planning for these drivers. In other words, sufficient attention by planners and city managers to the influential factors and drivers and considering these key factors and the relationships between them will provide the necessary conditions for providing housing for low-income groups in the city of Tabriz.

Geo-marketing is a tool that uses geographic, or location-based, information to help companies put together marketing strategies and campaigns. Using digital mapping to organize and display data enables marketers to analyze data by region or a particular physical location. Geo-marketing can be used to choose a website for a new business or branch, determining key locations for advertising, displaying website content that is distinct to a user’s origin, and offering online advertising based on a user’s location. Other applications include showing how a customer segment might be distributed in particular. Geo-marketing is a new way of knowledge-based marketing, which is supported by digital maps and specialized GIS software. Knowledge-based marketing use packaged information such as marketing information systems, such as model building, data mining, etc., to determine customer profiles, deviation analysis, and trend analysis.   Location Intelligence is a technical way to organize spatial data with business and human data in a geographically correct way in order to reveal hidden relationships that may lead to benefitting a business and/or avoiding spatially wrong located investments. Digital urban environments and e-cities in the rapidly evolving world have created many opportunities for people's living, working and entertaining environments. Therefore, the purpose of this study was to provide a model based on e-city management for the development of e-cities with the data theory approach which was particularly applied for Tabriz city as a case study. This research was in the framework of a qualitative approach and by applying the data research method of the foundation. The data collection approach was semi-structured interviews and 28 experts were selected using purposive sampling method to collect information. Data analysis was performed in three stages: open coding, axial coding, and selective coding in GIS environment. Based on that, a qualitative research model was applied.

The research methodology was developed based on the GIScience approaches. This technology is the spearhead of geospatial research in a) the connection between technology and thinking, b) training and, c) professional upgrade.  All of the above tools are essential for the improvement of a business because they are real time data, they can collect, visualize and analyze their client’s assets in real-time in combination with the real world of a satellite image or any other aerial imagery (i.e. image from a drone) and the process of the data in real-time. This allows an almost instant updating of the maps used by the business. This can be done when the business uses web mapping software in order to update its database. All web mapping software is on the cloud and gives the opportunity to be used from any place any time by any employee of the company who has the right to do so. Also, the database is on the cloud and can be retrieved accordingly.

The results of the present study show the identification of 367 open sources, 22 subcategories or concepts, and 6 categories of extraction and their characteristics. In this regard, the extractive categories were categorized as follows: Causal conditions: lifestyle change, smart governance (participation), reduction of environmental damage and the development of new technology and social networks, pivotal conditions: individual and social requirements, achieving sustainable economic development and information technology, ruling context: Infrastructure platforms, electronic infrastructure, financial and legal indicators of the country and the status of communication networks, intervention conditions: managerial, educational and cultural anomalies, strategies: upgrading infrastructure, using the experiences of other countries and localizing them, establishment Electronic unit window, using IT managers, culture and education, consequences: improving the quality of services and welfare and satisfaction of citizens, comprehensive development of the country and reducing pollution, traffic and environmental damage. The results of the present study are of great importance in the development of concrete electronic city management on data processing techniques and can pave the way for future research for the implementation of electronic cities. Results also indicated that  the Janbo store is well located spatially and has a chance to build up a  successful business. Results of this research are of great importance for developing a GIS by bridging GIS and marketing and presenting a new approach for GIScience.

Today, the issue of development is a concern of many countries. And many local authorities around the world have already begun long-term development for the community and have perfected international best practices for comprehensive development planning and analysis. The central district of Jiroft township has been selected as the scope of the present study; Which in various fields affecting development, has a considerable distance from national and international standards; In terms of development indicators, it is one of the deprived areas of Iran and in this regard, it is a considerable distance from international standards. Different areas affecting poverty, lack of educational facilities, lack of infrastructure and infrastructure are some of the factors that have made it inevitable to address the issue of development in this region. Distribution of selected indicators in the sustainable development of rural areas in the central district of Jiroft.

In line with the purpose and the question; The nature of this research is descriptive-analytical and applied in terms of purpose and based on library studies. The statistical population of this research is the five rural districts of the central district of Jiroft township and the sample size has been omitted. Selected indicators have been collected through the statistical yearbook of the Statistics Center of Iran in 2016. It should be noted that in the first stage, about 80 indicators were selected and in the final selection process, considering the discussion of access to statistical and spatial data, the number of indicators was classified and adjusted to seven general indicators. After extracting the indicators, the weight of the indicators was obtained using the TOPSIS model. At this stage, the rank of rural areas in the central district of Jiroft township was obtained with emphasis on selected indicators; Then, for spatial analysis of the weights obtained from the Shannon entropy stage of the TOPSIS model, and in the next stage, spatial maps were drawn using cluster and non-cluster analysis.

Accordingly, the present study has extracted and studied seven development indicators according to the selected sub-indicators to measure the development of rural areas in the central district of Jiroft township. According to the distribution of the mentioned indicators; It can be concluded that the scope of research is very different from the standards of development and the indicators of development are not normal and balanced. On the other hand, measuring the development indicators of the research area shows; That the study area is not of equal value. The analysis of the findings shows that Halil village is developing in terms of sustainable development indicators. Esfahan, Islamabad, are in a semi-privileged state and Dolatabad and Khatunabad are in a deprived situation; This indicates an unfavorable situation and far from the desired standards of development at the global and national levels in the study area.The results of this study on the level of development with the results of United Nations research (1991); Andriant (2001); Ghanbari et al. (2010); Aliaei and Azizi (1397); Mohammad Manan and Reisi (2015), which were mentioned in the background section of the research, are consistent. Accordingly, all of the above research confirms the lack of equitable distribution of services and facilities, as well as the lack of careful planning for regional development, regional inequality, and the lack of integrated development.

The analysis shows that Halil County is developing in terms of sustainable development indicators. Esfaandaghe, Islamabad, are in a semi-privileged state and Dolatabad and Khatunabad are in a deprived situation; This indicates an unfavourable situation and far from the desired standards of development at the global and national levels in the study area.Also, in order to find regional inequalities and eliminate these inequalities, it is necessary to level the regions and regions in terms of development. By recognizing regional inequalities and ranking them at the district and regional level, better management of regions can be done and according to strategies such as creating planning areas at the provincial, city and district levels, implementing policies. And bottom-up programs Given that most decisions are made in Kerman province in Kerman city, such centralist policies should be reduced and special attention should be paid to the opportunities and limitations of each townships. These are some of the things that can help reduce inequality in the area under study.

In essence, creativity involves experiences, innovations, the capacity to rewrite the rules, unconventionality, a new attitude to the affairs, innovative illustration of possible scenarios in the future, distinguishing common points from different points, and adopting a resilient approach to life. A creative city is a conducive environment for human development that lays the ground for developing its residents’ creativity. These cities usually enjoy dynamic and healthy spaces. Thus, it is imperative to pay attention to the factors affecting a creative city to create urban interactive spaces. These factors include human capital, innovation, social capital, and life quality. These factors affect the citizens and overshadow their sense of attachment to such spaces, thus preventing social anomalies.

Despite similarities with their nature, various scientific research methodologies also have differences, requiring the researcher to use appropriate methodologies consistent with the research subjects and consider the limitations that may arise. This descriptive-analytical research used the survey method to examine ways to improve effective and creative innovations in the urban planning of new cities. This research stresses the effects of human capital, innovation, social capital, and life quality on the creative city. Later in the text, the research addresses each of these indicators and ranks different districts in the new city of Rudyan.This research falls under extensive research categories (e.g., the city of Rudyan) and is a cross-sectional study. Data were analyzed by SPSS software programs and multi-criteria decision-making technique (DEAMTEL-based ANP). In the descriptive section, the study uses one-dimensional tables, percentages ad frequency, while in the inferential section, T-Test tests, two-sample t-test (independent samples t-test), path analysis, Pearson, etc., were used to test the hypotheses. Also, the DANP model was used to rank the factors affecting the materialization of a creative city.

The new city of Rudyan has an average innovation index of 2.01, which is not desirable. This indicates that the new city stands at a lower rank than other cities across the nation regarding the application of technology, innovation, science, etc., and it is required to take more measures to become a creative city.The new city of Rudyan has an average social capital index of 2.74, which is not desirable. Speaking of social capital variables, the city acquired an average rate of 2.88 in the cooperation and collaboration in social relation network (the best situation), while it held an average rate of 2.34 in the variable of social trust (the worst situation). Considering the significance level of less than 0.05 (i.e., 0.003) for all social capital variables, the results from the indicator understudy can be generalized to the whole community.The new city of Rudyan has an average quality of life index of 2.74, which is not desirable. Speaking of quality-of-life variables, the city held an average rate of 2.94 in the variable of urban culture (the best situation), while it held an average rate of 2.10 in the variable of the environmental situation (the worst situation). Considering the significance level of less than 0.05 (i.e., 0.003) for all variables of quality of life, the results suggest that the city of Rudyan has, like other variables, an undesirable quality of life situation.

As social trust increases, human capital, innovation, social capital, and life quality will also improve. This is also true of the city of Rudyan. A significant relationship was found between interpersonal trust and human capital with quality of life. There was also a significant relationship between social capital and the creative city, i.e., with the development of social capital components, creative city indicators will also develop (as in the city of Rudyan). The research findings revealed that social capital was a good predictor to explain the city of Rudyan’s creativity.

 Public health and sanitation as an important and vital issue has always been considered by academicians and urban planners and managers. It has led to adopt policies and actions by governments and related organizations. Though, creating healthy cities is a long-standing idea that has been around for decades, but in recent months, as the Covid 19 epidemic, which usually spreads faster in crowded cities, has plagued every country in the world, it has received more attention again. One of the concerns of city planners and managers in the current situation is how to protect the living environment and create resilient cities against such diseases. One of the approaches that has been proposed in order to enhance health in human habitats is healthy city idea. The purpose of this study is to analyze the status of healthy city indicators and the spatial distribution of these indicators in the new city of Sahand.

 The study area of this research is the new city of Sahand, in the northwest of Iran, at a distance of 20 km from the city of Tabriz. The city has an area of 498 ha and a population of 80795 people. In the research, 38 indicators were selected as indicators of a healthy city and were classified into 4 dimensions. Part of the data was extracted from the GIS file of the 2016 Iranian Population and Housing Public Census and the other part was gathered through a survey using a questionnaire. Sample people including 378 household heads. The data was entered into the GIS to form a uniform shapefile. Then, by producing spatial distribution maps, spatial analysis was performed. Then, by transferring the data to SPSS software, a one-sample t-test was performed.

 T-test results showed that the mean of the 38 indicators is 2.99, which is slightly lower than the assumed mean (3). Among the four dimensions of the indicators, the physical one shows a better situation the others, so that the figure is 3.69, which is 0.69 higher than the assumed mean. As the city has constructed in recent decades in accordance to a pre-designed plan, the indicators have shown a better situation in this regard. After the physical dimension, the environmental one shows a higher value than the assumed mean and it was 3.33.In terms of environmental dimesion, relatively large distance from pollution resources, being enclosed in a valley and northwest winds, has removed air pollution from the city. The low density of cars on the roads has caused the residents to be satisfied with the lack of noise pollution. Connecting almost all the houses to the municipal sewage network, proper slope of lands, low density of population and the absence of worn buildings are some of the environmental advantages of the city. At the same time, poor waste management and non-observance of environmental cleanliness by citizens are low-scoring indicators in this dimension.The values of socio-cultural and economic dimensions are lower than the assumed mean.  Their values are 2.63 and 2.52 respectively. High value of the indicators of literacy, safety and security are the three indicators with higher values in this dimension. Onthe contrary, medical facilities, cultural services, leisure and sports facilities are indicators with a lower value in this dimension. In the economic dimension, except for employment, insurance coverage and job satisfaction, the other indicators show a very low value.In terms of spatial distribution, the indicators of a healthy city in Phase 1 of the city has a better situation. In this Phase, the average valueof the indicators is 3.08. In Phase 2, in the southern parts, it has a higher value, but the in phase 2, it is slightly lower than the assumed mean (2.97). At most areas of the Phases of 3 and 4, where construction is still ongoing and service coverage, infrastructure and facilities are not completed, the value of  indicators are low. In Phase 3, the average value of the indicators is 2.95 and in phase 4 it is 2.76.

Analyzing healthy city indicators indicated that Sahand represents a medium situation of a complete healthy city. In this city, for reasons that are mostly originated from national economy, there are many shortcomings in the economic indicators of a healthy city. However, due to the existence of a proper labor market near the city, unemployment rate is lower and insurance coverage is higher than most cities in Iran. But due to inflation, the incomes of the urban community, most of which are salaried, have not been able to provide them with the goods and services they need to live healthily. Due to the government's financial inability in recent years, it has not been made sufficient investment in urban services, facilities and infrastructure.The dormitory function of the city and the low financial capacity of its resident could not provide the municipality with the necessary financial resources to invest in  developing urban facilities and infrastructures . In terms of spatial distribution, in the zones and phases where the construction was done earlier (Phases 1, 2, 3 and 4, respectively), indicators values were higher than new constructed ones. In areas under construction or semi-residential, market conditions lead to less private sector activity.

One of the main problems in worn-out and dysfunctional fabrics in today's cities is not paying attention to the concept of social issues or factors as one of the important capacities in urban localities, since the traditional communication and interaction system has changed drastically in most big cities.  One of their worrying manifestations is the weakening of social relations among the citizens.  The evolution course of urban regeneration has shifted from paying attention to physical dimension to social, economic and cultural dimensions during about three decades of theorizing and implementing the urban regeneration approach, and it has led to the emergence of community-based urban regeneration.  This approach has sought social interaction and an emphasis on the role of social groups. Also, according to the results of urban regeneration measures in different parts of the world, the trust and participation of citizens, as an effective component in the success of regeneration projects, is not be spontaneous and requires the involvement of many factors and it is achieved by social issues by involving in the process of regeneration.

The methodology of this research is applied in terms of aim. It is also survey based on the research method, conducted by using a questionnaire. The analytical section of the research was conducted by survey method using a questionnaire. Accordingly, the opinions of 379 citizens of the three studied localities, who were selected using a convenience random method, were used. Also, to determine the validity of the questionnaire, the Delphi method was used by a number of experts and university professors, and by obtaining the opinions of the mentioned people, the necessary corrections were made in the questionnaire questions. Thus, it was ensured that the questionnaire measures the desired variables of the research.  Cronbach's alpha coefficient was used to calculate the reliability and its value was estimated at about 0.65. Descriptive and inferential statistics were used to analyze the collected data. Then, data were entered to SPSS software and a multi-criteria questionnaire based on a 5-point Likert scale, ranging from very high to very low, was developed to evaluate five indicators and 36 variables of the level of satisfaction of citizens living in the study areas. Then, to check the normality of data distribution, Kolmogorov-Smirnov test was used and to check the status of research variables, sign test was used. Also, the weighting of variables was done by entropy model and ranking of localities was done using MABAC technique.

Ahvaz metropolis with an area of ​​31800 hectares, as the third largest city in the country, has several worn-out fabrics in its eight urban districts. In the metropolis of Ahvaz, 30 to 35% of the city limits are within the legal limits and are known as worn-out fabrics and non-allowed settlements. Out of 124 localities in Ahvaz metropolis, more than twelve localities are considered as worn-out urban fabrics. In the present study, to evaluate the performance of social issues in worn-out and dysfunctional fabrics of the three studied localities (Khazalieh, Ameri and Hasirabad), five indicators (social belonging, social cohesion, social cooperation, social security and social trust) and 36 variables according to the studies were selected. The present article revealed that based the results of urban regeneration measures in different parts of the world, the trust and participation of citizens as an effective component in the success of regeneration projects will not be spontaneous and require the involvement of many factors and it is achieved by social issues (sense of social belonging, social cohesion, social security) by involving in the process of regeneration.

Considering the 50-year history of government involvement in dysfunctional urban fabrics, new and diverse methods of intervention in urban fabrics are being carefully considered nowadays. Little attention has been paid to social factors. The general results of the sign test show that Ameri locality with a mean of 3.16 has a better status than the other two localities in terms of research variables. Also, the results of MABAC technique show that Ameri locality with Si value of 0.260 is ranked first, followed by Khazalieh and Hasirabad localities with Si values of 0.076 and -0.164 are ranked second and third, respectively, in terms of five selected indicators. The main issue of this study in comparison with previous studies is that any change in the improvement and modification of research variables in each of the studied localities, including social and individual behavior of residents, social relations of neighbors, locality social security, locality service facilities, cooperation among residents (residents’ participation), trust and belief of locality residents to each other and to the government, the interaction of service providers with the residents of the locality, etc. is very difficult due to the social conditions of these localities (different ethnicities, low literacy, low-income classes, inadequate security, improper education, high birth rates, etc.). The main reason can be the social and cultural characteristics of these localities and getting used to this lifestyle over the past few decades, which have shown resistance to any change.

Atmospheric mineral dust particles play a key role in the radiation budget of the atmosphere and the hydrological cycle, and have an important effect on public health by disrupting climate systems and air pollution. Due to Iran’s location in the arid and semi-arid belt of the world, Iran is constantly exposed to local and regional dust systems. Considering the importance of the negative effects of dust storms and their increasing trend in some dust sources, the study of these changes in the last two decades show the importance of the dust storms in recent years. Moreover, spatial-temporal identification and analysis of the properties of these dust particles is very important in order to manage this crisis and prevent the harmful effects of dust particles. In Iran, due to desert conditions, the presence of dust hotspots has always caused air pollution and reduced the quality of life of people. In recent years, some dust hotspots have been ambiguous about increasing the intensity of dust emission. In this study, using the AOD product of MODIS, which compute the dust intensity, and based on the annual frequency and averages of dusty days, the location of dust hotspots were identified and then the trend of dust intensity in each hotspots were examine. The results showed that despite the relatively similar climate, the trend of changes in these dust hotspots does not follow the same pattern and complex human activities and natural changes.

 In this study AOD product from MODIS with the resolution of 10 km was used to extract dust information then the frequencies of days with AOD greater than 0.6 per year were extracted. In addition to correctly calculating the average of AODs, calculating the number of days without data is also important in the results. The spatial and temporal distribution of the study period, were identified in three periods, 2000-2006, 2007-2012 and 2013-2018. The percentage of changes in each of the dust sources compared in different periods. The standard deviation was extracted to identify the areas most vulnerable to dust storms. Finally, to detect the quantitative distribution, the trend of AOD changes in the extracted dust hotspots was used to investigate the changes in the dust intensity trends.

The map of dust hotspots in the first period shows the main dust sources are in the north of Sistan and Baluchestan (Zabol) and south of Sistan and Baluchestan (Chahbahar), in the southeast of Semnan (Dasht Kavir), Damghan, Garmsar, Jazmourian, southwest of Hormozgan, (Bandar Lengeh area), south and southwest of Khuzestan, southwest of Yazd (Nayer), as well as parts of Qom, Ilam (Mehran), Isfahan, and south of Fars provinces. In the second period of study, many dust centers have become more intense and extensive. According to the map of dust centers in the third period of studies, compared to the first and second periods, the area of dust centers has decreased.According to the results, about half of the areas without emission has been turned into areas with dust with different frequencies in second period, and also about half of the area of ​​very high-frequency hotspots has been turned into other dust sources with less intensity in the third period. Also, the most fluctuations in dust intensity have occurred in Sistan, Jazmorian, southeast of Semnan, East Azerbaijan, Zanjan and Khuzestan provinces. The results of trend analysis of dust intensity in different dust hotspots show that despite the relatively uniform climate, the dust sources trends in different dust sources do not follow the same pattern.

Due to the geographical location of Iran and the existence of vast deserts, the wethear has always affected by dust sources of inside and outside of the country. In this study, using satellite data with appropriate resolution, the location of dust sources in three time periods were extracted. The changes of each dust intensity class in the second and third periods were compared with the first period so that regardless of location, changes in dust intensity can be evaluated in general. Then, using the standard deviation method, the dust hotspots with the highest percentage of changes were identified. Finally, the trend of changes was calculated by examining the trends of changes in 24 main dust centers. According to the results of the present study, many changes have been observed in some dust sources and the intensity of dust in many dust sources has decreased. While some sources such as Isfahan, and Khuzestan province due to the role of human factors such as agricultural activities as well as the reduction of surface and ground water and as a result of drought and changes in soil texture have an increasing in trend of dust intensity. Since a decreasing trend is observed in most of dust sources, eastern and southern parts of Iran, the results of this study indicate the key role of climatic factors in changes and fluctuations in dust emission in Iran. Because climatic factor can be the only factor which has a relatively uniform effect on the dust emission on a large scale of Iran.

Over the past few decades, the social sustainability of urban areas has become an important planning model in developed countries. The present study aims to assess the social sustainability of urban neighborhoods in District 15 of Tehran with an emphasis on the land-use mix index. The land-use mix and distribution of activities are among the factors affecting the social sustainability of urban neighborhoods. These two factors are examined with items such as accessibility of land-uses, distribution of land-uses, diversity and equality of land-uses, age and compatibility of land-uses, design considerations in land-use planning are examined. And social sustainability, as a dependent variable, is investigated at the urban neighborhood level with items such as involvement and empowerment of local communities, sense of belonging to neighborhoods, security and health, capital and social solidarity, the cultural identity of neighborhoods, vitality of neighborhoods, social accountability and sense of neighborhood.

The present study is applied, descriptive-survey research in which data are collected using both library and field studies. Using a library study, the required indices are extracted by reviewing relevant studies and theories on land-use mix and sustainability. First, the land-use mix measure of each neighborhood is calculated using Shannon entropy and the studied indices in the neighborhoods are ranked using the COPRAS method. Due to the lack of a standard questionnaire on the research subject, a researcher-made questionnaire is used. The statistical population includes urban managers and experts as well as the residents of the study areas. The sample size is estimated to be 385 using Cochran's formula. The questionnaires are distributed according to the population of the neighborhoods. The reliability of the questionnaire is estimated to be above 0.8 using Cochran's alpha, indicating that the items or questions are fully related to each other. To analyze the relationships between variables. Spearman's correlation coefficient, descriptive and inferential statistical methods such as one-sample t-test and Kruskal-Wallis test, are used in SPSS software.

 In total, 81.2% of the respondents are men and 17.9% are women. Most of the respondents are in the 38-52 age group. The results of Shannon entropy show the weights of each land-use mix index, with the greatest weight (0.9943) for the component of accessibility to land-uses and the least weight (0.7542) for the component of design considerations in land-use planning. The studied neighborhoods are at different levels in terms of social sustainability; so the neighborhoods of North Afsariyeh (NJ= 98.23), South Afsariyeh (NJ= 96.83), and North Kianshahr (NJ=84.23) have the best situation in the land-use mix indices while the neighborhoods of Hashemabad (NJ = 27.043), and Minayi (NJ = 22.43) are in the worst condition.

The results of the research show that in the studied neighborhoods, "accessibility to land-uses" (β = 0.485), "the density of land-uses" (β = 0.482), and "the distribution of land-uses" (β = 0.479) are the most important indices of social sustainability, respectively. The social sustainability of urban neighborhoods is affected by several factors, one of which is the land-use mix index. The present study is conducted to investigate the social sustainability of urban neighborhoods in District 15 of Tehran with an emphasis on the effectiveness of the land-use mix index. To investigate the social sustainability of neighborhoods, the following indicators are studied: involvement of local communities, sense of belonging, security, social capital, cultural identity, vitality, and social accountability. Moreover, to investigate the impact of the land-use mix index on social sustainability, the following indicators are investigated: accessibility of land-uses, land-use density, distribution of land-uses, land-use diversity, age, and compatibility of land-uses, are design considerations in land-use planning. Weighting land-use mix indices using Shannon entropy shows that the greatest weight (0.9943) belongs to the "accessibility of land-uses" component. In the next step, in order to measure the social sustainability of urban neighborhoods, the VIKOR method is used.

Access to open spaces in urban areas is one of the important principles of passive defense. This is because of the large number of post-crisis casualties, mostly due to the inability to access outdoor space as well as the ability to escape the danger zone.

 The aim of this study is to investigate and accessibility of open spaces of urban areas in case of emergency from the perspective of passive defense of region 1 of Tabriz. For this purpose, in this research, related software such as 10 ARC GIS, Auto cad and Excel software have been used to zoning different spaces based on vulnerability and also to analyze information.

The results and findings of the study indicate that 67.3% of Tabriz Region 1 is in a good position in terms of access to open space in terms of passive defense against crises. But to increase the quality and quantity of these conditions to the desired level, improve the functional condition of open spaces (green and enclosed space) and increase the width of streets and alleys leading to the open space.

so that quick and easy access to the organ is possible. Provides things like volcanism, etc. in times of crisis, is of particular importance.
