Abstract Urban decayed texture is the most important potential for using urban land, for housing, providing open spaces and services, and improving the environmental qualities. On the other hand, these contexts are a practical solution to prevent the physical expansion of the city from underdeveloped lands around the city and the development of empty and abandoned lands within the urban area that can help revitalize  the city. In this regard, the main aim of this study is to identify the capacity of decayed texture to construct housing. Research method is descriptive-analytical in terms of nature, and applied in terms of purpose and aim. In order to achieve the goals of the research, spatial data and performing relevant analyzes in GIS and multi-criteria decision model AHP, VIKOR, SAW has been used. The statistical population were urban planning experts of Isfahan, and the sample size is 30 experts, based on theoretical saturation, and snowball sampling is used to choose the experts. The results of the two methods of VIKOR and linear weight combination showed that out of the total area of ​​Sarcheshmeh neighborhood, in VIKOR model 336354.29 square meters and in linear weight combination model, 15213.59 square meters have high capacity for housing production. Since the number of pixels on the utility threshold is higher in the VIKOR model, the output of the VIKOR model is preferred to use the decayed texture to provide future housing.

Abstract The accelerating rate of urbanization and population growth in the past three decades in developing countries, especially in Iran, has brought many issues in social, economic and political aspects, and made it necessary to urban managers to prepare a comprehensive plan in the housing market. For such a program, assessing the housing indicators is a necessary tool to estimate the needs of housing sector in the country. Aim of this study is accomplish the spatial analysis of quantitative and qualitative indicators of housing in city of Izeh. Research method is theoretical-applied, based on the goals, and descriptive-analytical, based on data gathering. To measure the difference between the five regions of the city , 9 quantitative and qualitative indicators of housing have been applied. Then, after collecting information and statistical data, the fuzzy TOPSIS decision-making technique and GIS were used. In the fuzzy TOPSIS decision model, zones 2 and 3 with weights of 0.582 and 0.588 estimated as rich, zones 4 with weights of 0.392 and was semi rich, and zones 1 and 5 with weights 0.368 and 0.364 were poor. In general, the final result of this study shows the mismatch between the distribution of quantitative and qualitative indicators of housing in the regions of city of Izeh .

Abstract Today, the widespread presence of vehicles, as well as the growing share of Passenger rides in the structure of cities, has created problems and caused sidewalks to be reserved only for places of passage. However sidewalks can play a complementary role in connection with other transportation networks and improve civic life in urban centers. In this study, the aim is to assess the desirability of urban sidewalks based on qualitative components in Naderi sidewalks in Ahvaz. The present research is theoretical-applied in nature and descriptive-analytical in terms of study method. Data collection has been Librarian and from the field. The statistical population of the study includes pedestrians and residents of Ahvaz commercial center. 320 pedestrians and residents were randomly selected as a sample size during one week. Data reliability was calculated by Cronbach's test to be 0.813. SPSS statistical tests were used to analyze the data. The results of the analysis show that the rare sidewalk in Ahvaz is far from the characteristics of a desirable sidewalk. Among the studied indices, the attractiveness and vitality index with an average of 2.96 and accessibility with 2.82 have a more suitable situation than other indices. It should be noted that safety, furniture and mixed uses on the sidewalk should be given serious attention. So that citizens can walk and have fun freely and with complete safety and comfort.

Abstract The main objective of research is the spatial modeling of the land use map of Hamadan city to produce the noise pollution map. This research is applied in terms of purpose and descriptive-analytical in nature. Theoretical data were collected through library and research projects, statistics, existing books and articles, urban plans. Field information was also collected by observation method. In order to analyze the data, we first used the multi-variable model (FAHP) to evaluate the weight of the indicators, then the principles and criteria of neighboring criteria were extracted and identified and using the ARCGIS Tool Euclidean Distance was exploited. Generated maps do not have homogeneous units, In order to standardize is used to standardize and homogenize and also increase their flexibility from Fuzzy Membership fuzzy logic. After valuing and determining the weights, The results exert its influences in the GIS environment were affected by the Raster Calculator option in the layers, and finally using the Fuzzy overly tool with a 0.9% gamma The maps of layers in question have been integrated and spatially analyzed. The analysis of the results shows that in the area with very low risk of 7.34 percent of the total selected uses, the zone with a low risk of 6.02, a zone with a mean risk of 7.49 percent, in the zone with a high risk area of 38.67 percent of the number of 1354367035 existing uses is included.

Abstract Today, the challenges of modern urban life and environmental and social problems have led to a futuristic approach to urban planning and the use of various tools to build a desirable future. The present study uses the technique of cross-impact analysis, which is one of the common methods in futures research, and using Mick Mac software, has analyzed the components of urban development in the metropolis of Ahvaz. Then, 37 components were extracted as indicators of urban development using the Delphi method. The results indicate that six categories (influential factors, risk factors, purpose, influential factors, and independent factors, regulators) can be identified in the scatter page. Finally, among the 37 key factors, after examining the impact of these factors on each other and the future situation of the metropolis of Ahvaz by direct and indirect methods, 13 effective and key drivers were identified, including; (Population, equitable distribution of urban services, development of tourism industry, organization of special tourism axes, organization of suburban areas, control of air pollution and promotion of environmental health, expansion of public open space and creation of leisure centers, providing the appropriate level of economic growth, improving quality of life in dilapidated urban fabric, organization, and improvement of worn-out fabric, expansion of small and high-yield workshops, empowerment of non-governmental organizations, development of recreation and tourism centers) which have the most role in the future state of urban development in Ahvaz, were selected as factors and drivers Affecting the urban development of Ahvaz. The results further show that the factors of "development of the tourism industry, organizing the suburbs" are at risk. Population factors, fair distribution of urban services, development of the tourism industry, will have the greatest impact on the urban development process of Ahvaz metropolis.

Abstract Recognition of spatial inequality and regional imbalances in the context of different geographical areas and policy-making to eliminate and reduce item is one of the most important categories of regional planning. The dimensions of spatial inequality in various economic, social, medical, and other fields are debatable. Therefore, achieving comprehensive progress and development in the future requires recognizing the position of regions and areas in different dimensions. In this regard, the present study has been conducted to measure the spatial inequality of the metropolitan area of Ahvaz in terms of possessing a combination of development indicators. According to the studied components, the article approach of this study is "descriptive-analytical". This study tries to determine rating and measuring of inequalities amone the regions of Ahvaz city using 54 variables and applying the ELECTRE model. The results of this study show that the distribution of development is unbalanced and there are inequality and gap between regions in terms of development, and this inequality appears to be in different sectors of social, economic, service, health, and physical. According to the results of the electrical technique, region 2 is at the level of enjoyment, region 1 and 3 are at the level of semi-enjoyment, region 4 is at the level of low enjoyment, and regions 6, 7, and 8 are in the category of deprived or lack of enjoyment; Therefore, to reduce the level of development inequalities in Ahvaz؛based on the research findings, it is suggested that the distribution of development indicators Should be directed towards balanced growth.

Abstract Today, planners believe that environmental quality is a key concept for regional and social planning and is associated with concepts such as quality of life, diversity of social space, physical characteristics, activities, spatial dependencies, and urban identity. Therefore, improving the quality of the environment has become one of the main goals of policy makers and urban planners. The purpose of this study is to investigate the importance of environmental quality components from the perspective of tourists in Isfahan metropolis. The research method in this study is descriptive-analytical and the data are prepared by survey method. The statistical population of this study includes tourists of Isfahan metropolis, which using a Cochran''s formula, a sample of 384 people was randomly selected and studied. This number was questioned through a questionnaire whose validity was tested using Cronbach''s alpha method. In this study, in order to analyze the data, the statistical approach of structural equation modeling (SEM) and the second-order five-factor confirmatory factor analysis test were used. The final results obtained from the elimination of the effects of measurement errors in the structural equation modeling approach, indicate the effectiveness of the evaluation of the tourist community of environmental quality, respectively, environmental, aesthetic and formal, semantic and perceptual dimensions, and finally functional and activity.

Abstract Urbanism, urban growth and its undesirable expansion as global phenomena, affect all countries throughout the world. In recent decades, the growth and extension of urban areas has come to be considered as a kind of issue or problem and Ahvaz appears to possess such problem. The aim of this study is practical and its methodology is descriptive-analytical. the present study seeks to investigate the physical development of Ahvaz Extension pattern of Ahvaz in the 2021 horizons. First the process of physical extension is investigated during the period from 1981-2017 (35 years) and 14 indicators has been extracted for the study of the appropriate extension of Ahvaz development in 2021 horizon. By using of FUZZY logic, these indicators have turned out to be standard and by the use of analytical-combinatory model of ANPDEMATEL for the optimized model, 3 levels have been determined for the extension of this city, which has been consequently extracted in the combination of OVERLAYFUZZY and 0/9 GAMA in the GIS environment of output maps also using ENVI and arc GIS software. The results showed that at the level of predictive models of agricultural land with weights of 0.101 and 0.118, the most important and important factor has been the physical development of the city of Ahvaz. Also, the output of physical expansion on the horizon of 1400 showed that the best location in the immediate area of the 8th district of the city and not being located on the site of agricultural land in this city.
