Geomorphological Territorial Planning for Residential Development Based on Fuzzy and ANP Models Integration in South of Razavi Khorasan Province

Study and understanding of geomorphological factors limiting the formation of new settlements as well as natural disaster management is the essential and necessary. On this basis, in the present study the territoial planning geomorphological residential areas south of Razavi Khorasan province has been the development of residential areas. Methods such is, the first layer of information provided, and fuzzy and have been comparable then, using ANP model calculated the value of each of the layers. Finally, each of the layers in Arc GIS software using the command Raster calculator in weight obtained by ANP model multiplied and using fuzzy logic data layers are combined. Finally after the overlay, map of suitable areas for urban development in the study area based on combining the fuzzy model and ANP have been obtained. According to the final result of suitable areas for purposes of urban development is divided into five class. Reviews zoning map and the classes it represents unfavorable geomorphological conditions much of the area for construction activities and the creation of new settlements. Approximately 59 percent of the study area which has an area of about 17545 square kilometersm, the classes are very unsuitable and unsuitable located and approximately 19.5 percent the study area has an area of about 5786 square kilometers is The classes are very suitable and suitable are located, Which indicates the limitation of appropriate places according to the geomorphological conditions area for construction activities and construction of new residential areas. The studied area is geomorphologically potent with a lot of restrictions due to the presence of mountainous, hills and sand dunes that need to be considered by planners in development projects.
