Abstract
Urban development is one of the important issues raised in the field of planning, and in the world it means improving productivity and better use of land and space, and it is influenced by factors including natural factors, such that the development of cities with natural bedrock and geomorphological effects is facingDue to the increase in population and the need to use the land around us, it is necessary to make intelligent planning in the field of sustainable urban development in terms of geomorphological phenomena and hazards. The existence of geomorphic hazards and the dynamics of the natural environment sometimes make it difficult to evaluate all factors at the same time in order to determine the appropriate location, so the use of efficient methods is one of the planning measures for urban development.The purpose of this research is to locate the physical development of Sufian city based on geomorphic factors using the AHP-Fuzzy model. To do this, the desired layers, elevation classes, slope, slope direction, lithology, distance from the fault, distance from the waterway, drainage network , land use, distance from the road was prepared.Then weighting was done in Expert choice software. Criteria of distance from fault with coefficient (0.218), distance from waterway (0.191), land use (0.155), distance from road (0.130), drainage network (0.102), slope (0.075) ), lithology (0.063), elevation classes (0.055), slope direction (0.011) are respectively the most important influencing factors in the physical development of Sufian city.By combining the results of AHP-Fuzzy and GIS, the studied area is divided into 5 unsuitable floors with an area of 15/90, relatively unsuitable 16/18, relatively suitable 16/59, suitable 16/53, very suitable 67 / 31 square kilometers were prioritized, the northern and eastern parts are in unsuitable areas and the central and southern parts are in very suitable areas.
