With the increasing development of cities, villages, industrial areas, roads, etc. the study of slope stability and determine of the risk value are essential. Among the methods for determining the relative risk of landslide and its zoning, quantitative and semi-quantitative methods gives better results. One of the semi-quantitative methods is Analytical Hierarchy Process (AHP) that uses the method of paired comparisons to analyze the multiple criteria. In this study, to remove ambiguity in the opinions of human, the combination of AHP and fuzzy system for landslide hazard zoning in Kamyaran County that is located in the south of the Kurdistan province, was used. In this research, in addition to usual factors in landslide risk zoning, two factors of slope shape, i.e. plan curvature and profile curvature, were used. The results show that the 52.03 percentage of area had a low and very low risk and the remaining area had medium to very high risk. Among the studied factors, slope, litho logy and land use have had maximum effect respectively, and slope shape had minimum effect on the instability of slopes in the studied region.
