The aim of this study is to synoptic analyze of the number of frost days in a year of Khuzestan province. For this purpose, using the minimum daily temperature data of 12 stations during the statistical period of 1992 to 2017, the Meteorological Organization of the country, 54 days of frost was identified. Sea level pressure, Geopotential Height, Zonal and meridian wind and temperature of 500 hPa data with size of 2/5 * 2/5 degree arc from the National Oceanic and Atmospheric United States of America were extracted. On the matrix of the variance of sea level pressure data in 54 days, the analysis of the basic components was performed and 10 components which identified 83% variance of the sea level pressure. Then, by applying the hierarchical cluster analysis method, the integration method was applied to the scores of the 10 components and 5 patterns of sea level pressure were identified. The results showed that frost phenomenon in Khuzestan province occurs from November to march and its trend is decreasing during the statistical period. Also northern and western parts of the province have allocated the most frequency of frost. Also the synoptic condition analysis of troposphere showed that 5 sea level pressure pattern with different make ups lead to pervasive frosts of Khuzestan province. Weak and moderate frosts formed by the influence of Siberian and European cold high pressure systems. But severe frosts occur with spread of Iceland low pressure to Iran, along with strong cold pressures. Meanwhile, the powerful Siberian high pressure is present in most of the patterns, which its interaction with sub polar and Icelandic low pressure, plays the most role in the most severe frost in the province of Khuzestan. Also in the middle level of troposphere penetration of deep troughs from northern latitudes and east European huge blockings has the most role, which has advection of cold air from the side west of troughs on the country and during the intensity of the frost added to its continuity.

Considering the unfavorable environmental conditions of cities, the shortage and defects of open and green spaces in metropolitan cities, the need to pay attention to parks and green spaces of the city in terms of ecological and social functions of these spaces has been discussed more than before. For this purpose, this research has been investigated. And ecological analysis of regional parks in Tabriz city. The present research is analytical-descriptive in terms of its purpose. The information was collected in both documentary and field and analyzed using the GIS.

Spatial Analysis of Crimes at Different Hours of the Day, the Days of the Week, Month, and Seasons is an Effective Way to Control and Prevent Urban Crime. These analyzes give city management and other city safety officials, including law enforcement officials, the possibility to take preventive measures to eliminate or mitigate the effects of these factors in the city. The purpose of this study was to investigate the spatial analysis of theft crimes on a daily, weekly, monthly and seasonal basis in the 12th metropolitan area of Tehran. The research method in this article is descriptive-analytic. The comprehensive statistical data included the statistical blocks of 1390 in the neighborhoods of the 12th district of Tehran and the crimes related to theft in 2010. The most important statistical tests used are the Center-Medium and Oval-standard deviation tests, and from among the clustering tests, the nearest neighbor index is used to identify massive cores. The results of this study indicate that 446 crimes related to theft, Ferdowsi and Lalehzar neighborhoods, and Sachr('39')di Baharestani have the most crimes and minorities in Kosar and Mokhtari. The pattern of distribution of crimes in the 12th region is clustered and the most important crustal focal points are formed at the intervals of the Shemiran, Iran, Baharestan - Saadi, Ferdowsi -Laleh Zar, Arg Pamenar, Imamzadeh Yahya and the Cascade. The spatial analysis of stealing crimes also suggests that the direction and extent of theft is different at different times of the day, weekdays, and on a monthly basis.

The border regions (periphery) are far away from the center due to remoteness, geographical isolation, lack of development, and ... great differences in terms of prosperity and development with central centers. Creating and operating a border market can modify the one-way central- Around and improve regional prosperity. The purpose of this study was to investigate the role of the border market in Henijan province in Khuzestan province in the socio-economic development of the region. The population of the population is Hendijan city which consists of 26292 people according to the census of 2011. Using Cochran formula, 380 people were selected and the questionnaire was distributed among them. The questionnaire has five components: economic, social, transportation, urban services and infrastructure, and 27 sub-criteria. For data analysis, the Fuzzy Network Analysis (ANP) and inferential statistics of Chi-Square have been used.Based on the fuzzy ANP model, the construction of the bazaar has had the greatest impact in reducing smuggling, increasing the stores and shops, hotel and restaurant construction, attracting tourists, increasing passenger terminals, increasing service occupations, boosting banks and insurers, earning income, employing indigenous people and reducing immigration. had. Based on the results, the market has the most impact on the economic component and the least on the underlying component.  The fuzzy network analysis model indicates that the market has been most effective in improving. the conditions of which of the components and sub-criteria has the most effect in helping users and planners in the region to use the cost to improve other components

Assessment of the landchr('39')s capacity for urban development in the sense of objectifying the potential of the land is among the expected and executable applications. On the other hand, increasing urban population, followed by the growth of cities, due to the expansion of urban development makes moving toward the principles of sustainable development an indispensable act. Kerman as one of Iranchr('39')s major cities encountering with limited natural and human development, is not an exception. Thus, it is essential to take into account its development structure. This study aims to identify the fertile lands for future development of the city of Kerman. This study is functional in nature and purpose and descriptive-analytic in methodology. In order to achieve the purpose of the study, the method of fuzzy Analytic Hierarchy Process (AHP) and Boolean was employed, and finally by combination of maps, appropriate lands for future development of Kerman were identified. The results of this study showed that the lands located in South, Southwest, and North and northwest of the city of Kerman are in a better position for future development compared to other parts of the city.

Reducing the vulnerability of urban users in order to reduce the amount of damages using non-factor defense approaches that can be effective in creating a safe environment in cities. The most important goals is todaychr('39')s planners and urban managers are planning to implement it in cities. The aim of this study was to investigate the safety of urban spaces against earthquakes due to the principles of non-factor defense and identification of safety mitigation factors in District 5 of Shahre Ray. The research method is descriptive-analytic to explain the current situation and the response to research questions. Data collection method was based on the field of Venice Library (questionnaire) and analysis of data obtained using frequency test and factor analysis. Then, the fundamental variables of influence were analyzed by Pir-son correlation test for the effect or rejection of assumptions. Finally, the findings show that what is considered as the basis for the work must determine the different stages of an earthquake planning process in Tehran and It is a shahre ray that must be used when preparing any comprehensive or detailed plan and case. The results of the study showed that physical, economic and environmental factors (can influence the reduction of urban space Vulnerability (in area 5 Shahre Ray). At the end, offers and guidelines for the preventive observance of the principles of non-operating defense in Shahre Ray has been presented.

In many developing countries, including Iran, urban development is one of the most important factors in land use change. Most cities, in their turn, have caused the destruction of agricultural land and have been covered by urban expansion. This is a matter of economic and agricultural activity, especially in province like Gilan, due to temperate climate and fertile soil, which is one of the things that demands that appropriate planning prevent the uncontrolled expansion of these cities. In this regard, we aimed to study the land suitability analysis as a tool for planning and predicting an optimal urban development model in cities under the multi criteria decision making (WLC and TOPSIS models) in the GIS and based on various indicators at Foman and Shafts in western Gilan. The results showed that the output classification of the two models used was different, but suitable areas for urban development were overlapping in two methods. The most suitable areas for urban development are found in northern and eastern parts. Also, land use has the highest importance in zoning. Based on the results, the inner development of the cities is recommended as the first priority.

The attachment to the place is the emotional relationship of the individual to the place, which is rooted in the personchr('39')s past qualities and experiences that the place should be able to meet the needs and expectations of the individual, and also the place must meet the capacity to meet those needs and expectations. The attachment to the location is based on the cognitive, emotional, and functional interaction between individuals, groups, and physical-social location over time. The purpose of this study was to use the meta-analysis method to analyze the results of research on attachment to the place. In order to perform a meta-analysis, 75 researches were conducted in this regard. Among the 18 studies conducted during the years 2006-2019, in the field of attachment to the place were selected. In the first step, the evaluation of selected research, homogeneous assumptions and publication error was studied; accordingly, the findings indicated the heterogeneity of the size of the effect and the non-dominance of the published studies. In the second step, the coefficient of effect size was evaluated using the second version of CMA software. The results showed that the size of the effect or coefficient of influence of the identified factors is 0/376, which is evaluated according to the Cohenchr('39')s interpretation system. Overall, the results indicate that the identified factors have a moderate effect on attachment to the location.

This study was conducted with the aim of providing a remotely sensed water quality index in Assaluyeh port using remote sensing technology. so, according to the region conditions, studying of scientific resources and access to satellite data, the parameters of heavy metals, dissolved ions, SST, chlorophyll-a and pH were selected. Then, by reviewing sources, the product MYD091km, MYD021km, MOD021km, MOD091km and level2 images of chlorophyll-a and SST of MODIS sensor were used after preprocessing operations. Also In-situ data were collected Simultaneously with the capture of satellite images in August 2014. Then, the relationships between the water quality parameters and MODIS data, with (R2) from 0.59 to 0.94 and (RMSE) from 0.07 to 0.1 were obtained. Next the images of the MODIS sensor from 2015 to 2017 were prepared and the models were applied to them, then the layers were standardized by fuzzy logic. Also time series of SST data from 2003 to 2017 were prepared and for each month the average pixel values were calculated and based on this, from 2015 to 2017, the variation of this parameter was standardized. Finally, an effective index for assessing the quality of coastal waters was provided by time series of satellite images and the waters of Assaluyeh port were zoned. The results showed that the water quality in 2015 and 2016 has shifted from poor to very poor status in 2017. Based on the results, with the development of a proposed index, in future studies a continuous assessment of environmental monitoring is possible.

Examining the effects of climate change on the oak spatial distribution, as the main species of Zagros forests and its ecological and economic values is of significant importance. Here, we used species distribution models for simulating current climatic suitability of oak and its potential changes in 2050 and 2070. For this purpose, five regression-based and machine learning approaches, four climatic variables related to temperature and precipitation and two optimistic (RCP 2.6) and pessimistic (RCP 8.5)  greenhouse-gas scenarios were used. The results of measuring the accuracy of models by AUC indicated the good performance of all algorithms and Random Forest achieved the highest accuracy (AUC = 0.95) among other methods. The results showed that in both time periods and under both scenarios, changes will occur in oak spatial distribution and the most severe one would be a 42.9 percent loss in the oak climatic suitability in 2070 under pessimistic scenario (RCP 8.5).

this study is designed to investigate the impact of micro climatic factors on optimizing energy consumption in Tehran urban buildings. The present study is of applied purpose and analytical method. Libraries and documents were used to collect the required data. Design Builder software was used to achieve the purpose of the research. The information given to the software is the thickness of the walls: exterior 20 cm - internal 15 cm, south windows (double shell balcony with 40% glass), northern windows 30%, brick exterior walls with natural ventilation were used. The results of this study showed that the orientation of the building on the site due to Tehran climate and the results obtained from Ecotect software was rotated about 25 degrees to the southwest to prevent direct sunlight from the east and west. And reduce the heat loads on the building. The volume of the building was designed in a stepped fashion, and while it could aesthetically enhance its strength, it could reduce the wind load on the upper floors. Green roofs were also designed on the exposed roofs, and according to the results of the analysis, the green roof can be very effective in reducing heating and cooling loads. The eastern and western fronts were also considered to be non-popping because of the results obtained in Design Builder software for daylight, which may result in dazzling workspaces such as kitchens sometimes day in the year.

In recent years, one of the main approaches to rural development and increasing the well-being of rural households is the development of rural tourism. Because tourism development can play an important role in the well-being of households as well as in rural livelihoods. The aim of this study was to investigate the effects of tourism on improving the welfare of coastal villages in Chabahar. The present research is a descriptive-analytical approach. The statistical population of rural households is Chabahar (N = 3720). Using Cochran formula and quota sampling method, 280 households in 6 coastal villages with tourist attractions are selected as samples. To analyze the data and to answer the research questions, unlimited exploratory co-univariate test, variance analysis and multivariate regression were used. The results showed that in terms of economic welfare indicators, tourism had the most effects on seasonal employment, income growth, housing development, and local economy mobility. In terms of social welfare indicators, tourism has the most impact on improving leisure time, changing lifestyle and lifestyle, developing health facilities, and increasing the sense of belonging to local people. Also, the results showed that tourism in the villages of the study area had significant effects on the economic and social well-being of rural households, but compared with social indicators, tourism had the most impact on economic well-being and its indicators. In line with the findings of the research, suggestions were made regarding the development of rural tourism and the welfare of rural households.

Geotourism is kind of responsible tourism with the aim of socio - economic development and strengthening of the scientific tourism destinations and tourism geological locations that emphasizes the protection of the heritage of the land and people of Sciences. Requires the development of a geo-tourism destination is recognizing its value and capability concept and planning barriers and providing favorable to its management. Tourism zone of Tangeh Vashi in the city of Firouzkoh, with different geological phenomena and scientific and complementary values, ​​is geotourism destination in local and sometimes national level. Therefore, in this study, using a variety of assessment methods geotourism area of ​​land that was presented in 2015 by Brill. In this, steps were taken. Therefore, the optimum user Tangeh Vashi Tourism, Economic User scientific approach - protective. The results shows that in generally, Tangeh Vashi has suitable condition in educational and tourism values. Also, Risk of collapse in Tangeh Vashi is relatively high. According to the results, the optimal management of geotourism Tange Vashi, the powers of access and the center of the provincechr('39')s population and strengthening of the complementary and diversity of geological and strengthen tourism and the preservation interpretation capability along with the application the physical protection and promotion of scientific partnership rural and legal controls.

Religious tourism, as one of the ways of development, cultural exchange and social interaction between nations can have many benefits for any society today. Enjoying indigenous cultures and local religious ethics is an important factor in attracting tourists. The city of Khorramabad has special religious ethics, such as the celebration of gellmalli in the Ashura Day and the chehell manbarr in Tasoa day, which can have a profound effect on this. Therefore, the present article, using descriptive-analytical method, and questionnaire, interview and observation tools, and with the assumption that indigenous religious-cultural ethics increase the value and importance of tourist attractions at the destination, has attempted to survey the role of chehell manbarr in tourism development of  Khorramabad city. The results of one sample T-test at the significant level of 0.000 indicate the impact of all three indicators of abilities and potentials in the chehell manbarr, visual beauties and custodians of urban organizations such as Culture and Islamic Guidance, Municipalities and other related organizations Is above average; Also according to the results of one-way analysis of variance at the error level below 0.05% , it is vary the effect of the index of abilities and potentials in the chehell manbarr ceremonies, and the effect of metropolitan organizations such as culture and Islamic guidance and municipality according to the educational levels of the respondents. However, the results of one-way analysis of variance for the extent of visual beauties on tourism inclination are similar at the educational level of the respondents. The results of regression analysis at the significant level of 99% show that all three variables of keeping of urban organizations such as culture and Islamic guidance during the chehell manbarr ceremonies, the abilities and potentials in the chehell manbarr ceremonies and the creation of visual beauties have a direct and significant effect on the tendency to Tourism and motivation for future trips.

The present paper deals with the analysis and analysis of spatial justice and its relation with social capital using descriptive-analytical research method. To assess spatial justice, the distribution of urban facilities and their per capita amount (per capita of religious, educational, medical, green, cultural, etc.) are used at local level. Then, they have been ranked by the multi-criteria decision-making method of Vicar County. According to the rates obtained from the vikor method and considering the final points, Shams Tabrizi and PehrAbad neighborhoods are in a state of affairs and the property districts, Sheikh Taj and TapaliBagi and Ohadi have a favorable situation.  The low-grade journals are in the new textbook and informal settlements. In areas such as Jahangir, Daneshghah, Sahand, Valiasr, Azadegan, new structures have been built as residential settlements over the past two decades. In the second stage, in order to evaluate the social justice of social capital indicators, a questionnaire was used that 383 questionnaires were prepared in relation to the population of each neighborhood. Five key indicators (trust, partnership, engagement, membership and security) have been used to assess social capital. The results show that neighborhoods such as Shams Tabriz, Khaje Nasir, Khan, Seidlar and Daraie have the highest social capital. In the third step, Pearson correlation methods and weight geographic regression have been used to analyze the relationship between spatial justice and social capital. In this method, the correlation between variables is shown in the neighborhood level. Output layer The standardized residual geographic weighted regression analysis between spatial justice and citizenschr('39') satisfaction shows that in Shams Tabrizi, Azadegan, Khajeh Nasir 1 and 2, Sheikh Taj, Daraie, and Pasdaran, there was a positive spatial relationship. This means that the spatial development of these areas has a positive impact on improving the quality of life and social capital, the greater the spatial justice in these areas will increase social capital.

Increasing urbanization in the urbanized world has posed major challenges to the sustainability of metropolitan areas, especially in developing countries in various aspects of sustainable development, and has provided them with the prospect of unsustainable development. Excessive land use and its consequent land use changes and land cover are one of the environmental problems caused by the high concentration of population and activity in metropolitan areas. This study is an applied one in order to monitor the environmental changes caused by spatial expansion of Tehran metropolitan area by descriptive-analytical method and by using remote sensing and GIS techniques land use changes and land cover caused by spatial expansion of Tehran metropolis. Has evaluated and analyzed Tehran. The results indicate that the area of ​​land increased from 34316.1 hectares in 1365 to 68252 67.95 in 1595/6117 hectares related to changes in agricultural lands, orchards and water area. Be it. The results of the Markov Chain Model prediction of the probability of land use changes and land cover up to 1405 also indicate that land use and land cover changes will continue in favor of constructed lands. It is concluded that Tehranchr('39')s metropolitan area has expanded beyond the demographic and ecological thresholds and has led to a significant structural disruption to the environment by moving toward the natural environment. Accordingly, the need to pay attention to new approaches to urban development as well as to provide decentralization scenarios can be a major step towards resolving environmental problems caused by over-spatial expansion.

"Governance" is one of the basic concepts that has attracted the attention of geo-political scientists, and there are contradictory views on this concept, which is one of the main and fundamentally important foundations of the science of geopolitics. The rule of law over higher power and superiority imply that no other legal authority is superior to it. Since the study of sovereignty in political geography is very important, therefore, it is necessary to examine its dimensions and spatial levels. Political geography focuses on the study of phenomena, processes and political currents, and emphasizes their geographic and spatial effects. One of the most important studies in political geography is the study of the country. Each country is made up of three elements of "nation, rule and land".. The linking factor of these three elements is "sovereignty". In political theories, they regard the sovereignty of that government and do not attribute it to any government or government agency alone. At the same time, in no political theory, the notion of sovereignty is not absolute, and it is believed that sovereignty must be exercised within the constitutional framework and in accordance with the law. Land is the space of the state, which, with the spatial scope of the territory, determines the sovereignty of the state, and as the physical container, it includes the body of the political organization. The present article seeks to elaborate on the fact that "sovereignty has different dimensions and levels". The present research is of fundamental type and has been done by descriptive-analytical method. Data collection method is library and computer. Also, data analysis is also qualitative.

Based on the notions and assumptions of the discourse of “new urban regionalism”, there is a close relationship between the "spatial morphological structure" and the "spatial division of labor" in a megalopolis region, and solving existing problems in one without another is not possible, because they can either act in the direction of positive reinforcement and support, or in order to weaken and become an obstacle to each other; therefore, what is meant by the problem of achieving equilibrium and integration in the spatial structure and the functional system in a megalopolis region, will not be possible without recognizing the nature and relationship between these two. The reviews done the research shows that "spatial morphological structure" and "spatial division of labor" in Tehran's megalopolis region during the recent decades has not been able to support each other and significantly reduce the spatial non-equilibrium in the region. Therefore, according to the results obtained in the framework of this study, the "spatial morphological structure" and "spatial division of labor" in Tehran's megalopolis region during the recent decades (1345-1390), has been accompanied by a significant reduction in the spatial non-equilibrium in the region, though, the trend of transformations is on the move. One of the strategic implications of this is that the future issue of the Tehran's megalopolis region is to be more focused on the peripheral population poles and the improvement of the level of performance of the city itself in order to accept transnational functions and create alternatives and opportunities for roles and the tasks that will be assigned to them in the future. Just as in the prior years the industry sector has gradually shifted to the service sector, in the future it also seems necessary to give up the services sector to itself periphery and oppose the acceptance of the fourth sector of the global economy (such as; Information, communication and cultural economy).

the aim of this study is to explain the impacts and impacts of organizations such as municipality on land use management in the tehran metropolitan area to determine and change land use patterns in documents and factors affecting them . because of the qualitative research approach and its type , the influence of organ and document content including land use projects in tehran was used . research findings show that land use management in tehran with conflicts in land use management , weakness in land use management , weakness in land use management system , weakness in land use management system , weakness in land use management system , weakness factor in land use management system , weakness factor in land use management system , informal and quasi - governmental agent and private agent are classified . finally , the change of land use change in tehran metropolitan area has been studied and challenges and opportunities are presented . the research method is analytical and by software soft ware and t - test .

The growth and expansion of the dispersed development pattern is one of the ways of settlement development that is shaped by a variety of factors, including urban management policies and approaches. Examine how the development of Tehran's metropolitan area has evolved over the last fifty years and what effective urban management policies and approaches have been and how it has influenced city development. This article deals with it. This research has been used because of the importance of the topic in a descriptive-analytical and practical purpose, based on library and documentary studies and in some cases field observations. In order to achieve the objectives of the study, three types of measurement models were used depending on the subject and variables of the study. In this regard, physical continuity in Tehran urban complex through Shannon entropy model, functional continuity through network analysis model (investigation of habitat and flow points and distribution and land use composition) and poor urban slope growth using Helder model The measurement is located. The findings show that: 1) dispersal phenomena have occurred in Tehran metropolitan area (Helderen and Shannon entropy model), 2) Tehran metropolitan area has been experiencing functional divergence (network analysis) and user distribution The services and services at the Tehran metropolitan level have not been uniform and balanced; and 3) the policies and approaches of urban management in successive years have had wide-ranging effects on spatial dispersal and unbalanced spatial development. Tehran's urban complex had.
