Taking Wumeng mountainous area in Guizhou province as the study area, by collecting landslide data and on-the-spot investigation records, a spatial database of 939 landslides and related influencing factors on GIS platform are established. The influence of altitude, relative height difference, slope angle, slope aspect, the shortest distance from landslide to rivers is studied. The results show that the number of landslides decreases exponentially with the shortest distance to the rivers. The most important factor affecting landslides distribution is topography and morphological, especially slope. The research can help human beings get along better with the surrounding nature environment and provide a basis and reference for environmental governance, landslide prevention and mitigation work.
