Abstract :
Due to the development of cities, a number of issues emerge as crucial problems in every-day life of human beings. One the one hand, the urban development, which is one of the essential aspects for the life and survival of human beings, cannot be limited, and on the other hand, it should be arranged in harmony with the needs of human being in a way that it does not damage environment. In the present study, it was intended to identify the optimal sites and districts for urban development through determination of environmental features, especially geomorphological features and the analysis of these features. In order to analyze these features, 13 indices were used. Each of the layers was fuzzed in the environment of Geographic Information System (GIS) through integration of Fuzzy Logic and Analytic Hierarchy Process (AHP). In the next step, multiplication operator, fuzzy addition, and fuzzy gamma were operated through multiplication of weight of layers resulted from AHP in each of the layers. The optimal gamma in ArcGIS was categorized in 5 proportion classifications. The results indicated that 9 percent of the studied site is categorized in the low-proportion class and 16.5 percent in high-proportion class. The map of the presented model determined the districts with potentiality of spatial development with respect to the past trends as well as suitable districts for future developments. Accordingly, Northern, Eastern, and Northeastern districts of Shahrekord City are the best and most suitable ones for future development of the city.
