According to the basic situation of the research region, six evaluation factors, including slope, aspect of slope, formation lithology, distance from the fault, rainfall and land use type were selected to evaluate the landslide susceptibility with GIS and AHP in Jiasa Town. The result showed five classes of landslide susceptibility, i.e., extremely high, high, moderate, low and extremely low. The results of landslide susceptibility evaluation will be useful for later watershed landslide risk assessment.
