    • Abstract
  • Landslide erosion is one of the serious disasters in Tongchuan City, Saanxi Province, China. This research project investigated the environment of landslide erosion disaster in Tongchuan City and its regularities.Then, the contour of the landslide erosion disaster quantity is figured with the field investigation information. With the contour map, landslide erosion intensity in the research area is divided into five zones with the intensities of serious erosion, strong erosion, medium erosion, light erosion and weak erosion. The total land area is 82.5 km2, in which there are 127 landslides. The landslide erosion quantity is 11 542.6×104t, occupies 92.9% of total erosion quantity. In which, the area of above medium erosion zone is 58.25 km2, occupies 70.6% of total area. It is suggested that the landslide erosion intensity in Tongchuan City is serious. To protect the safety of people's life and property, the alarm system for anticipating the disasters should be implemented urgently.
