【 摘 要 】

Geologic hazard mainly contain collapse, landslide, debris flow, ground fissure, surface collapse and subsidence. which had been influencing pepole's life and production greatly. The space distribution of geologic hazards of MianChi county were investigated by field survey. This paper both obtained the geologic hazard susceptibility and disaster risk partions map based on information value model. The article considered a total of 6 potential factors: slope gradient, slope altitude, slpoe style, structure of rock and soil, vegetation index and rainfall. The results conform to the actual outcomes and can be used for guiding practices.
