Effects of natural factors including lithology,soil,landform,rainfall and temperature on the hill collapse distribution were analysed based on the overall location survey and the establishment of GIS database.Characteristics of the hill collapse dispersion were first studied by means of GIS space analytic technology.It was found that the hill collapse principally occurs in the granite-red soil hill characterized by an average annual rainfall of 1 300-2 000 mm,an average annual temperature of 15-22℃ and a sea level below 500 m.The current research maybe instructive for the planning of the hill collapse and its prevention and control.
