Abstract Taking the Wushan County in Chongqing Municipality as object, the paper analyzes the characteristics of geohazards and influencing factors which include the topographic conditions, engineering geological rock formation, geological structure, slope structure, water level of the Three Gorges Dam and other human engineering activities. Based on information method, the ArcGIS software is used to extract and calculate the spatial information of each factor to get their contribution values to geohazards, and divide the susceptibility into ultra-high-risk, high-risk, middle-risk and low-risk areas. The occurrences of geohazards in different areas are counted respectively. It is found that the higher the susceptibility is, the more the geological disaster points there are, which is basically consistent with the actual situation, with good fitting degree. The result can be used to evaluate the susceptibility of geohazards in the same type of areas.

Key words： geohazard geological environment susceptibility information method Chongqing Municipality
