Abstract	Slope failure hazard usually causes great damages in mountain area. So, the regional slope stability study is very important and essential to engineering construction, regional planning, disaster mitigation and economic development in mountain area. This paper takes Daqu watershed from Donggu to Ranchong of the first stage of the west line of water Diversion Project from South to North of China as a study area. It chooses gradient, slope type, slope aspect, elevation difference, lithology, earthquake, fault and land use as factors to analyze the stability of regional slope. The factors are classified, quantified and overlapped by using GIS method. After analysis, the regional slope stability of the study area is divided into stable area, middle-stable area and unstable area, and the areas liable to slope failure hazards are delimited based on the possibility of happening slope failure hazards. At last, through the field investigation of slope failure hazards in the study area, the rationality of analyzing results is tested.
