Based on MAPGIS technology, the study used a composite index model, each factor calculated through the grey assemble theory and the Analytical Hierarchy Process (AHP), according to their weight. The factors were used for special algebraic addition. Geological hazards easy-happening areas can be divided into high-risk area, medium-risk area, low-risk area, covering 96.66, 113.37, and 23.96 km², respectively. The zoning was consistent with the practical situation.
