The Study of predispositor of landslides and grading extent of risk is essencial for future extensional activities.

Recognizing unstable regions or potential unstable slopes is the first step in managing earth activities with objects of smalling bionatural effects (socters and van wasten, 1996).Earth slip as one of most important geomorphic risks in north sloops of Binalood and studied domain that is from north slopes of Binalood (Zoshk- Sarasiab) is not excepted from this matter. In this research with object of determining effential factors in occurance of earth slips by using experintial model, Anbalagan, first prepared clear effort units, then, by determining wiegh of factors that are repersentative of level of informational role and domain operations, prepared the map of grading extent of risk of accurance of earthslip. Obtained results are representative of that 32.9% of region area placed in risky and intersly high risky extents, in aspect of accurance of earth slip.Recognizing and introducing these regions in aspect of slope movements. Can be important for domain's designers and managers, in local and regional levels.
