英文摘要	Regional slope stability is to study the possibility of slope deformation and instability from the view of regional scale. The paper took the Maerqu watershed from Makehe to Moba County in the upper reaches of Dadu River as the study area. Gradient, fault, slope type, elevation difference, earthquake intensity, lithology, rainfall and land use were chosen as the main factors to affect slope stability. These 8 factors were classified, quantified and scored firstly. Then the original maps of the 8 factors were overlapped by using the factor overlapping method. Consequently, the regional slope stability of the study area was divided into three types of regions: the stable region, the middle-stable region and the unstable region. The area of the unstable region is 810 km(2) which occupies 51.9% of the total study area. It is indicated that the possibility of slope deformation and instability of the study area is high.
