Third places serve as a manifestation of culture, identity, and civilization, providing an ideal platform for achieving a comprehensive perspective on the quality of urban environments and the quality of life of citizens. The aim of this research is to clarify the role of urban third places in improving the environmental quality of Ahvaz city. This study was conducted in 1402 in Ahvaz city using a quantitative approach, a survey method, and relying on library-documentary studies and the targeted Delphi method to identify conceptual indicators. The first statistical population consists of all Ahvaz citizens, totaling 885,000 people in 1395, of which 390 individuals were evaluated as the sample size using the Cochran formula and randomly selected through a researcher-made questionnaire. ANOVA tests, regression analysis, one-sample t-test, cross-effects analysis, and other statistical methods were used for data analysis. The second statistical population consists of 100 specialists and experts among city managers and urban management activists, of which 30 individuals were selected as the sample size using a targeted questionnaire and the snowball sampling method. The present study used the cross-impact analysis technique and the MICMAC program to analyze the components of third places and the environmental quality of Ahvaz city. Using the Delphi method, 55 components were extracted as indicators of third places and environmental quality in 10 dimensions. After examining the how and the extent of the influence of these 55 factors, 11 key factors that had the greatest role in the future state of the environmental quality of Ahvaz city were selected. The findings indicate that all 10 examined indicators were above the baseline average (3). Furthermore, in the regression model, it was revealed that the predictor variables explain approximately 74.1% of the variance of the criterion variable (environmental quality(. Region 6 with an )average of 0.84( had a higher superiority in terms of environmental quality compared to the other 8 regions of Ahvaz. The environmental quality and the level of satisfaction of Ahvaz citizens with urban third places have a strong relationship with the state of these third places in the city (with a factor loading of 0/722)
 

The population growth and physical development in Iranian cities, especially Ahvaz, has an increasing trend. The pattern of urban expansion in Ahvaz city has also moved in a new direction due to the rapid urbanization in Iran in the past several years under the influence of the urbanization process, population expansion and increase in immigration, so that the master plan has not been able to provide a suitable model for the expansion of this city to give. Therefore, one of the most important issues facing the development of this city is the location of its future development, and in this regard, natural parameters are considered to be the main factors that determine the directions of the physical development of Ahvaz city. Therefore, the purpose of this research is to identify and prioritize the natural criteria for zoning areas prone to physical development in Ahvaz city. The findings of the research showed that among the main criteria of the research, based on the fuzzy hierarchical analysis model, from the perspective of the research experts, the geomorphological criterion and then the natural hazards criterion are ranked first and second, and the research experts "Geomorphological" and "natural hazards" have been chosen as two of the main effective natural criteria in the future physical development of Ahvaz city. According to experts, hydrological, ecological and accessibility criteria are the third to fifth priority respectively

This study was conducted with the aim of analyzing the distribution pattern of land uses in the district 3 of Ahvaz. Land uses were evaluated at the regional, district and neighborhood levels by calculating indices of Compactness, Herfindahl-Hirschman, Fragmentation, Simpson’s Diversity, Entropy, Built-up Land Density, and analytical tools available in ArcGIS software, including ANN, DD and GWR analyzes. Therefore, this research was done with a practical purpose and a descriptive method, and the data was collected by a library method. It should be mentioned that so far a few articles have been written on the evaluation of the pattern of land use distribution by these methods and also on the case of the district 3 of Ahvaz. The study showed that in the district 3 of Ahvaz city, the existing per capita land uses wer 12 m2 higher than the standard per capita. Zone 2 had the highest density and compactness and zone 3 had the highest dispersion. Despite this, the pattern of distribution of land uses in the zone 3 showed more mixture, diversity, concentration and continuity. Spatial distribution of 46% of land uses was highly clustered and the land use direction towards the center of the district was favorable. This orientation attracted the population in the center of the district. As a result, Land uses in three Ahvaz regions do not have proper distribution and it is necessary to prepare a plan to organize land use.

One of the most basic principles of urban planning and management is to pay attention to the changes and transformations of the population and to know enough about its population structure. Considering that the effect of historical developments and social, political and economic factors on the balance of the population structure is not the same in all parts of the city, the city will face spatial changes in the population structure of urban areas. This issue has led to the formation of different needs among urban areas and the change of urban land use. The aim of the current research is to evaluate the role of population structures on urban land use changes in Ahvaz metropolis. In terms of practical purpose, in terms of descriptive-analytical nature and in terms of method, the present research is a combination of library and survey methods and is based on future research approach. The scope of the research was the city of Ahvaz. The statistical population of this research is 40 people of population and urban land use experts. For data analysis, the Delphi method, the cross-effects matrix (MICMAC) was used. The findings of the research showed that among the 39 main factors affecting the role of population structures on urban land use changes, 14 variables are known as key and influential. that these variables have the most influence and the least influence on the future development of the role of population structures and urban land use changes in Ahvaz city. Also, the results showed that in terms of the direct influence of variables such as immigration with a score of 71, social welfare and population density with scores of 63 and 61, and the variables that have an indirect effect on the population structure and urban land use change are immigration, population density and social welfare, respectively. They are located in the first to third positions.

The variables that have the most influence on the environmental future of high-rise development in Ahvaz city are population factors, attention to the economic values of recycling, access to sunlight, bicycles, lack of urban parks and open spaces, temperature, humidity, wind, touch, compliance of environmental laws with the landscape, ecological elements, land and soil conditions, pedestrian crossing, topography and geology, development of environmental diplomacy plans, smell, public transportation, and socio-cultural issues. Due to the high influence of the micro-climatic and socio-cultural factors regarding environmental sustainability on the high-rise building process by Ahvaz city officials, considering the issues can determine the success or failure of the sustainable environmental indicators of Ahvaz city high-rise development. Finally, solutions are suggested to improve the current situation, which require the serious attention of managers and urban planners.

Every year, a large number of tourists travel to other countries for treatment, and while using medical services, they visit the sightseeing spots of the countries. This method of tourism has become common in most countries of the world and as one of the dimensions of tourism, it helps the sustainable development and dynamism of the country's economy. Due to the low cost and high income of this industry, many developing countries focus their attention on this part of the industry and plan for it. Ahvaz city was done in terms of tourists. T-test was used to analyze the data and test the research hypothesis. Statistical analysis was done using SPSS software. The findings of the research show that the answers to the questions of medical, service and welfare infrastructures in Ahvaz city are equal to 3.41, which shows that the concentration of the answers is far from the average value (3). which indicates a large difference between the sample mean and the test value (3), so the hypothesis is confirmed. The results indicate that medical tourism as one of the pillars of tourism in general and medical tourism in particular has received the attention of many countries in recent decades and many of these countries consider medical tourism as one of the axes of creating employment. They have paid attention to earning foreign currency and so on and have taken significant measures in this regard. In Iran, in this phenomenon, in the fourth and fifth development plans, experts in the field of health and treatment and cultural heritage and tourism organization have received attention.

The city of Ahvaz, as the seventh metropolis of Iran, is known as one of the important cities of Iran with its centrality of industries, political centrality, border and security position, ethnic and social cultural diversity, but attention to the issue of passive urban defense has been neglected in it. has been Sports complexes are also among the important uses during crises and damage in cities. The purpose of this research is to locate sports complexes with passive defense approach using geographic information system in Ahvaz city. Therefore, paying attention to the role of sports uses in creating mobility and reducing the psychological pressures of urbanization, a suitable framework should be provided in order to choose suitable sports places and distribute them in the whole city with the aim of reducing damages during a crisis.Therefore, paying attention to the role of sports uses in creating mobility and reducing the psychological pressures of urbanization, a suitable framework should be provided in order to choose suitable sports places and distribute them in the whole city with the aim of reducing damages during a crisis. Therefore, from the point of view of passive urban defense, the need to pay attention to the proper distribution and placement of vital uses, including sports complexes, is inevitable for the city of Ahvaz. In this research, it has been tried to determine appropriate criteria based on the available sources in order to identify and determine the optimal location of sports complexes based on the passive defense approach. This research is applied in terms of purpose and descriptive-analytical in terms of methodology. In order to achieve the goals of the research, it has been done by using spatial data and performing relevant analyzes in the geographic information system and multi-criteria decision-making model SAW. In the next step, the indicators were weighted using the AHP-FUZZY questionnaire. Thus, the statistical population of this research is the experts of the urban area of Ahvaz city and the sample size is 30 experts through theoretical saturation. The results of the research showed that 0.60% of the city area is completely unsuitable, 3.74% is unsuitable, 21.44% is average, 46.92% is suitable and 27.30% is completely unsuitable. The final results of the research showed that the central and northern parts of Ahvaz city are suitable areas for locating sports complexes and these parts can be used to build sports complexes.

The issue of land and how to use it has always been the main issue and platform of urban planning, and in fact, the final fate of the urban development plan is determined by how to intervene and monitor the way land is used, and it is always one of the social, economic and physical issues in urbanization. Contemporary is formed by this category. Experimental planning is a type of spatial planning, this planning includes all levels of urban, regional, national and international planning. Land use as one of the conceptual components of land use is land use according to the type of activity. The aim of the present research is to investigate the distribution of administrative-government uses in the city of Ahvaz with the approach of urban planning. The descriptive-analytical research method is based on library and documentary studies and field investigations in the city of Ahvaz. In the analysis phase, using Arc GIS and Geo DA software, a spatial analysis has been carried out and the distribution of the population and government-administrative uses in the city of Ahvaz has been investigated. The results of the research have shown that the existing government-administrative uses of Ahvaz city do not have a fair distribution among the urban areas, and except for the 2nd urban area, the rest of the areas have a small share of these types of uses. Therefore, it is expected that city managers will realize the importance of balanced distribution of these uses, so that with their future actions and plans, the balanced distribution and allocation of government-administrative use to each of the areas while maintaining the practical coherence of this use and in line with the fair enjoyment of the said use by urban areas take a step and become the foundation of environmental sustainability.

Management in general is the art and knowledge of efficient and optimal use of resources to achieve the goal, and waste management or waste management is in fact all the planning and activities in the field of waste and in order to reduce, move, convert, Decontamination or disposal of waste takes place. Waste management system consists of different parts. This system can be compared to a chain that in the absence of a loop, the chain will be broken, so the performance of each waste management will affect other parts. Although the waste problem has been solved in many cities of the country and may have become a source of prosperity for the city,In the metropolis of Ahvaz, due to the lack of a clear strategy and proper investment in recent years, it has not been able to bring prosperity to the city and always a lot of garbage in the people, has caused a huge amount of dissatisfaction of citizens. In Ghizaniyeh section of this city, since 1991, with the closure of the old landfill in the "Broumi" area, it has been set up Non-disposal of garbage in a principled manner and according to the rules in this garbage site, provides the conditions for garbage to burn in this site and the smoke from this fire will burn the residents of Sofireh village and most of the villages of Ghizaniyeh section of Ahvaz city and east of this city. Has encountered a problem. One thousand tons of city waste is transferred to the Ahvaz waste site daily. The per capita waste production in the country is 700 grams per person, this per capita in Ahvaz is more than the national average per person. According to the latest statistics, the amount of garbage collected in 24 hours is close to 800 tons, which has decreased despite the fact that garbage collectors and dry garbage collect by them.

According to the research topic, the research method is descriptive-analytical. In this regard, first, using GIS software, the situation of waste landfill in Ahvaz city has been studied, then the geographical distribution of suitable places for waste landfill in this city has been studied. For analytical work, maps that have been in the form of polygons have been turned into rasters, and maps that have been in the form of point and linear features have been determined using the Euclidean distance to determine their importance in relation to the landfill. In order to determine all the maps, the importance of classification has been applied to them. Finally, using the FAHP method, the weights obtained from this method are multiplied in the obtained layers, and the final map, which includes the current location of the Ahvaz landfill and the proposed locations, is obtained. In the next stage, using the opinions of experts living in Ahvaz, managerial, economic, environmental and social indicators have been studied. In order to analyze the data, statistical and graphical analyzes in GIS and SPSS were used.

The results of the study showed that in terms of location and environment, the ambassador landfill site is in a good condition and the problems of Ahvaz city in relation to waste disposal are due to its proper management . The studies of this study show that in the spatial survey of Safireh landfill, environmental criteria have been relatively observed. Among the landfills around the city of Ahvaz, from 5 very unsuitable to very suitable conditions, Safireh site is in a good condition, which can be said that the location of this site is suitable in terms of environmental characteristics.

 According to the studies and using the opinions of experts, it can be stated that the waste problems of Ahvaz city originate from the same source, ie its production and lack of management. Also, the studies of this study showed that the economic criterion has been the most important factor in the view of experts in locating landfills. The results for the study of proper waste management at the source indicate that the component of proper waste management at the source is significant and will have a direct impact by reducing environmental effects, and the component of proper waste management at the source as one of the main factors And is decisive in reducing the environmental impact of Ahvaz. Finally, based on the research findings, suggestions were made to control the pollution of the waste site in the metropolis of Ahvaz and in the study areas.

According to the approach of the World Health Organization, elderly-friendly cities include those urban spaces in which the distribution of public services is such that it is most appropriate to the needs and limitations of the elderly. According to the statistics, the city of Ahvaz, like the whole country, is moving towards the aging of the population and old age.

The present research is applied-theoretical in terms of purpose and descriptive-analytical in nature and method with a survey approach.

As a result, there is a difference between the indicators of the elderly-friendly city at the level of 95% confidence. In other words, the indicators of the elderly-friendly city from the participants’ perspective did not have the same priority. Accordingly, the social status index with an average rank of 1.81 has the highest score, and the health services index with a score of 1.06 has the lowest score. The regional results also show that the significance level obtained from the Friedman test is less than 0.05. There is a difference between the elderly-friendly city indicators in the eight districts of Ahvaz at the confidence level of 95%. In other words, the elderly-friendly city indicators have not had the same priority from the point of view of the respondents living in the regions. So, Zones 1 and 8, with the average rank of 2.88 and 2.79, have the highest rank, and Zone 6, with the score of 2.21, has the lowest. Analysis of structural equation model to investigate the effect of indicators of the elderly-friendly city of Ahvaz according to the coefficients of determination (R2) showed that the changes in the variable are significantly dependent on changes in independent variables of the research. Due to being positive Subscription index and redundancy index and three values of 0.01, 0.25, 0.36, which are introduced as low, intermediate, and high GOF values and obtaining 0.50 for GOF, the appropriate fit of the model was confirmed.

The model explained to investigate the factors affecting the realization of the elderly-friendly city of Ahvaz also showed that the changes of the dependent variable depend to a considerable extent on the changes of the independent variables of the research. In other words, independent research variables can explain up to 50% of the dependent variable, indicating the proposed model’s desirability.

Collecting, managing and analyzing the required data is a basic precondition in the field of macro and integrated urban management. Today, this operation is feasible in the form of SDI, the evaluation and identification of its implementation platforms is one of its key issues. The purpose of this study is to identify the limiting factors for the creation and establishment of urban spatial information infrastructure in Ahvaz, based on the basic fuzzy model of the readiness index. The research data was collected in a survey and then analyzed in a spatial information infrastructure readiness model. Therefore, Ahwaz urban spatial information infrastructure has been evaluated in five organizational factors, human resources, information, technology and finance, and in the form of 16 decision criteria. In the first step of the research, the required data were extracted from questionnaires completed by experts and specialists familiar with SDI and GIS, from government centers and the private sector in Ahvaz. In the next step and after data collection, the values of general indicators and five factors were calculated based on the model used in the research. The general findings of the study showed that the readiness index of Ahwaz urban spatial information infrastructure is equal to 0.47. Evaluation of the studied factors of the model showed that the organizational factor is the most important limiting factor in the development of SDI infrastructure in Ahvaz and among the criteria, the highest and lowest scores have access to location-based software and individual leadership, respectively. In total, according to the results of this study, 44% of the 16 decision-making criteria (including 7 criteria) were below the average (50%), which acted as the main limiting factor in the development of Ahwaz urban location information infrastructure. Also, based on the results of this study, it seems that in the development of urban SDI in Ahvaz, non-technical factors can be more effective as a limiting factor than technical issues.

The issue of the quality of the urban environment has gained significant importance in recent years within society. It is imperative to prioritize the consideration of third places in order to foster local communities and enhance the well-being of urban life. The primary objective of this study is to identify the factors that influence third places and the quality of the urban environment.

This research employed a quantitative approach, utilizing a survey method and drawing upon targeted library documentaries and Delphi studies to determine conceptual indicators in the year 1402 in Ahvaz city. The sample size consisted of experts and specialists in the field relevant to the research topic, totaling 30 individuals. Through the application of the cross-effects analysis technique and the Micmac program, this study examined the components of third places and the environmental quality of Ahvaz city. For the purpose of this study, the Delphi method was employed to identify 55 components and 10 dimensions as indicators of the third place and the quality of the environment. The data was then analyzed using path analysis test with the PLS Smart structural equation model.

The analysis of the 55 factors revealed 11 key factors that have the greatest impact on the future state of Ahvaz's environmental quality. These factors were identified by examining the direct and indirect effects of the factors on each other and the future state of Ahvaz's environmental quality.The findings of the prioritization of the effective dimensions in the third places and the quality of the environment in Ahvaz city indicate that activity and utility indicators, perception, and mental image and relaxation are ranked as the most important factors.

There is a comprehensive and multidimensional relationship between the quality of the environment and third places in Ahvaz City. This is due to the fact that the enhancement of environmental quality in this particular urban area is closely intertwined with the robust structural interdependence among these fundamental factors.

The present study focuses on the impact of natural environmental and ecosystem factors on the happiness of the citizens of Ahvāz, within the scope of geographical health. The city of Ahvāz faces environmental issues such as air and dust pollution, lack of green spaces, marginalization and inequality in service delivery, waste and sewage pollution, water quality, and flood crises in the Kārun River basin.

SPSS and GIS softwares, and the Cocoso method were used for data analysis. The findings indicated that natural environmental and ecosystem factors have an impact on the happiness of Ahvāz citizens. Factors such as air and dust pollution score -0.132, waste and sewage status score -0.109, and flood natural hazard score -0.077, negatively affect the level of citizens' happiness. Moreover, there are differences among the studied neighborhoods in terms of the susceptibility of happiness levels to natural environmental and ecosystem factors, particularly in Kooye Alavi and Manba'e Ᾱb neighborhoods. Finally, some recommendations provided including improving the quality of the environment, utilizing the potential of the Kārun River, and optimizing the use of abandoned and neglected spaces along this axis, transforming them into attractive areas for people's presence.

Community-oriented development is an approach based on which urban management supports the participation of community members in decision-making and management, to use local knowledge and resources to implement more effective projects that play an effective role in urban development and citizen satisfaction, as well as the positive performance of managers. Therefore, it is considered one of the important categories of urban management. In this regard, the current research tries to provide a model of community-oriented urban management in Ahvaz City. For this purpose, the basic and standard dimensions of the community-oriented development approach, which includes social-oriented development based on capacity, cultural identity, social justice, empowerment, strengthening social participation, and social responsibility; It has been analyzed using the structural equation model and PLS software. The research method is applied in terms of purpose and descriptive-analytical in terms of method. The statistical population is experts and senior and middle managers of Ahvaz municipality. Using Cochran's formula, 383 people were selected as the sample size. The results of the pls analysis showed social participation index with a coefficient of 0.857, social responsibility index with a path coefficient of 0.675, social justice index with a path coefficient of 0.542, community-oriented development with a path coefficient of 0.448, empowerment with a path coefficient of 0.427 and cultural identity with a path coefficient of 0.412 respectively have the greatest impact on community-oriented urban management. Using this index in practice, although they differ in terms of importance, they should be taken into consideration in an integrated manner and together, and the greater importance of an index should not lead to ignoring other principles

The purpose of this study was to investigate the factors affecting urban sprawl and its impact on livelihoods in Ahwaz metropolis. This research is applied-theoretical in terms of purpose and descriptive-analytical in terms of method. The trend of land use changes showed that the amount of built-up area increased, and the area of ​​green and agricultural land uses and so on decreased. The results of Delphi method shows that economic, political-managerial, technological, social-cultural and natural- environmental factors have the most effect on the dispersal of Ahvaz city, respectively. Also, the results of the evaluation of the spillover effects on the biodiversity indices showed that spillover of the urban spill on the increase of the cost of public utilities and consequently the reduction of the quality of services, the weakness of urban service quality monitoring, environmental problems, security decline, public utilities, identity degradation and fragmentation. The landscape has been impressive. According to the results, zones 2 and 3 are very poor in terms of monitoring the quality of urban services and other areas of Ahvaz are in a very poor condition. Zones 2 and 3 of Ahvaz have been in moderate environmental condition, Zones 1 and 4 are low and other zones are very low in terms of livability. In terms of the scattered impact of urban overcrowding on reducing security to four levels of very low viability (areas 5, 6 and 7), low viability (areas 4 and 8), moderate viability (area 1) and high viability (areas 2 and 3) are divided. According to general urban uses, Ahvaz is divided into two categories of low and very low biodiversity, and areas 1, 2 and 3 are better than other areas. In terms of weakening urban identity and landscape, zones 2 and 3 are in the middle range of biodiversity, zone 1 is in the low range of biodiversity and other areas are in the low range of life.In the present study, for the first time, the factors affecting dispersal of the city and its impact on biodiversity are investigated.

Today's cities, especially in developing countries, have rapidly developed after the industrial revolution due to continuous population growth and urbanization, and this growth and development has had many consequences. One of these consequences or crises in human societies is rooted in social inequalities and the lack of social and economic justice, and has become one of the serious issues for urban planners and managers. The aim of this research is to evaluate the spatial justice in Ahvaz city based on its population distribution. The research method is descriptive-analytical and is based on the land use map of Ahvaz municipality and statistical blocks in 2016. In this study, 12 information layers were used as the physical layers of Ahvaz city. These layers were analyzed using the fuzzy gamma method, and the map of spatial justice status was obtained. Based on the analysis of the 12 information layers in Ahvaz city and their distribution, it was determined that most of the facilities and services are concentrated in the center of Ahvaz city, and approximately 46% of the city's area is in a very unfavorable situation. Only 5% of the total area of Ahvaz city has a very favorable status. In general, we have 15% of the city's area in favorable and very favorable situations in Ahvaz. Also, according to the analysis, about 33% of the population of Ahvaz city are in a situation of lack of access to services and facilities. Based on the findings, it can be concluded that spatial justice does not exist well for all citizens in Ahvaz city, and the centralization of the city has deprived many of the city's residents of suitable and accessible services and facilities. Population analysis and land use distribution indicate a mismatch in the distribution of services and facilities based on population distribution.
