landslides are such as risk of mountainous areas that every year Imports a lot of damage on country economy. In recent years, natural and human factors Has caused Exacerbate the damages caused by landslides . One of the ways to reduce the damage caused by landslides is to avoid risk zones. For this purpose is necessary, risk maps for these areas be provided up any construction and development carried out by it. Main purpose this study is identify Effective factors of landslide occurrence in Darrud basin and Assessment areas with potential landslide for mapping using analytic hierarchy process and frequency relative method. In this regard, The first ten factors of landslides in the area were identified And using Arc GIS software raster was prepared and classification. Weights criteria using the Analytic Hierarchy Process and sub-criteria weights using frequency relative determination and landslide susceptibility map was prepared. Map produced using ROC curve was tested and it was determined that mapped by area under the curve 81/0 has the power to predict the landslide hazard assessment is very good. Slope 40 to 60 degrees, concave slopes, elevations less than 2,000 m, range between 300-330 mm rainfall, between 100-200 meters from the river, 0-100 meters from the road, 100-200 m of the fault, and northeast slopes and the gardens the greatest weight is given to them self. Also Factors aspect, land use and roads were identified as the most influential factors.

Keywords: landslides, zoning, frequency relative, AHP, Darrud basin.
