Based on filed investigation and previous research, eleven elements including relief amplitude, slope, aspect, lithology, precipitation, NDVI, land use and so on that contribute to the occurrence of landslide were selected as the risk evaluation factors. Finally, 15 active landslides with sliding displacement were utilized to validate the accuracy of the model. According to susceptibility map, the study area was classified into five categories, i.e., very high dangerous zone, high dangerous zone, moderate dangerous zone, low dangerous zone and very low dangerous zone, taking an area proportion of 21%, 26%, 37%, 11%, and 5%, respectively.
