This study analyzes the spatial distribution of population among districts in Ahvaz by ranking them. The research way is descriptive analytical models and taxonomy, SAR, SAW, entropy , Kapland and borad index is used. The population is eight area of Ahwaz metropolitan. Ahvaz city, according to latest census of 1390 the population was 1112668 and intern of distribution and access to municipal services, population growth is not appropriate. The correlation coefficient obtained with a value of 0.619 indicates that the distribution and population density in the city of Ahwaz, there is a weak relationship. Combining the results of the model show in 1 area looks increase in population and in region 6,7 and 8 in order to increase the level of coordination between the needs of the population and service so we can say with a balance distribution of service across metropolitan areas in Ahwaz according to the needs of population can reach a balance in urban areas. Therefore, the relationship between the distribution of the population and services in eight districts in Ahwaz to achieve sustainability and social justice seems necessary.

The urban thermal island phenomenon has intensified in recent years, due to the changes in urban airspace along with the rise of urbanization. Spatial-temporal patterns of biophysical constituents, which include vegetation, impermeable surfaces and soil type in the city, have a significant impact on urban thermal islands. The purpose of this study is to investigate the role of effective urban parameters in the formation and clustering of Yazd urban thermal islands. In order to achieve the proposed goal, the thermal map was developed using the single-window algorithm on the thermal band of OLT sensor of Landsat ETM+ sensors for August, 2015 and 2017; Land surface temperature (LST) was calculated and using spatial correlation (LISA), hot and cold clusters of thermal islands of Yazd were extracted. In order to evaluate the surface temperature, with the intensity of LST, spatial heterogeneity of the clusters increases nonlinearly. The relationship between the thermal islands with NDVI and urban carrion layers were investigated: cold clusters are around the places with more green space and hot clusters are in the arid areas and in areas without vegetation cover. The result of the correlation between the surface temperature and the NDVI, NDBI, and NDBaI indicated that the relationship between NDVI and LST is negative, and the relationship between NDBaI and LST is also nonlinear and negative. But the relationship between NDBI and LST is nonlinear and positive. A spatial correlation with the local index has emphasized on the extent of thermal islands in the studied periods.

In recent years, the rapid growth of cities has caused many urban problems. These problems have affected all aspects of urbanization and may have disrupted urban life. One of the most significant problems in cities is the presence of worn-out textures, which is the source of many urban problems, , all of which have created instability in cities. Cities are a product of a process that enhances the efficiency and mobility of development agents to meet the needs of human communities. This means that the physical and physical construction of cities has economic roots. Therefore, economic indicators play a decisive role in the modernization of urban decaying textures and increasing public participation.The purpose of the present study is to study the extent of market participation in the rehabilitation and renovation of the worn-out urban fabric of Ahvaz. The library documents and original references related to the subject under study were used to collect the theoretical background and theoretical foundations of the study. A survey questionnaire was used to measure the opinions and opinions of the research experts. After the opinion polls were edited, various opinions were categorized and analyzed. To analyze the research data is a VISUAL PROMETHEE model to determine neighborhood rankings based on market participation. The results show that among Ahwaz's central worn-out texture neighborhoods, the thirty-meter neighborhood with 0.69 ph + highest weight and the Ameri neighborhood with 0.24 ph + highest weight had the lowest priority for the effective criteria of Ahwaz central tissue marketers

The purpose of this study was to evaluate the capabilities of Ahwaz city in attracting foreign therapeutic tourists. Based on its nature and methodology, this study is of descriptive and analytical type; and based on the purpose, it is of the applied type. The statistical population of this study is consisted of therapeutic tourists and specialists and experts in the field of medical treatment. In order to collect information, two researcher-made questionnaires were used. One-sample t-test was used to analyze the data. The AHP method was used to rank the factors affecting the development of therapeutic tourism in Ahvaz city. The results indicated that the health, services and welfare infrastructures in Ahwaz are sufficient to satisfy the needs of tourists and this shows their high satisfaction with these infrastructures, but from the medical centers specialists and experts’ view point, the infrastructures are not sufficient. To determine the decision options, factors affecting the development of therapeutic tourism, medical resources, traveling services and marketing were considered.
