Evaluation of Environmental Indicator of Perimeters of the Land Suitability for the Development of the Sarvabad City by Combining Two Models of Network Analysis and Fuzzy Logi

Explosive, non-programmed growth of population and non-stop migration to the cities followed by rapid physical development in recent years caused many problems for cities and their inhabitants. The present study investigated the geomorphological status of the city of Sarvabad and assessed its capabilities for the purposes of urban physical development. In order to achieve the research objectives, reviewing the related literature and using experts' opinions were necessary and influential. Geomorphologic, geology, human parameters, including slope, direction of gradient, height, geology, land use, the distance from the fault, its distance from the river, distance from communicative way and distance from the urban boundary were determined. Then their communicative layers were prepared. For this purpose, two methods including fuzzy logic model and ANP were utilized. Firstly, the required layers were gathered and converted into fuzzy method. Then in the ANP model, the value of each layer calculated and network maps were integrated using fuzzy logic and finally presented as a map of the areas susceptible to development. The results confirm that about 25 % of the studied area which is located in South, East and Southeast section of the boundary need to be developed.
