Identification hazardous areas for Physical Development - Physical rural settlements with GIS (Case study: rurals of Suburban of Sanandaj city)

Assessing the ecological and land use planning for regulating the relationship between man, land and human activities in order to improve the material and intellectual conditions of community at the present time will prevent waste of natural resources and the environment as well as human poverty via introduction of the best natural land use based on the quality and quantity of the land and available socio economic needs. Therefore, this descriptive - analytical study has attempted to investigate to Using GIS and fuzzy logic evaluate ecological villages around of Sanandaj City with emphasis on factors endangering of physical development - physical in the future . In this regard, the ecological assessment, using the information in municipalities of Sanandaj city GIS database, data several layers were generated such as: distance from agriculture lands, gradient layer, the layer altitude, distance from the river, distance from green spaces and recreational space layer and layer fault . Finally, based on the value and importance of appropriated physical data layer in order to identify and rural settlements in ARCGIS10 were applied practical functions and algorithms. The results of combining standard layers based on used techniques, lands in the study area prioritized with emphasis on the natural factors then compared with land-use map. It founds that high ecological capability lands have been located away from faults, rivers and in the proper height and slope that were component of low risk areas. Therefore are offered for the future physical development of the rural.
