The geological hazard؛ in Changjiang Count',' of Hainan Province are controlled by geological environment condition؛ and influenced by various eternal factors. According to the detailed investigation data of geohazards in the area, the controlling conditions and inducing factors of various geohazards are selected as evaluation indexes, and the information analysis model is built by establishing the influencing factor system of geohazards. Through the quantification and normalization for each factor, the analytic hierarchy process (AHP) is used to determine the weight coefficients of evaluation factors, and the ArcClS spatial overlay analysis to evaluate the geohazard susceptibility in Changjiang County. This stud-,' will hopefijlly provide basis for geohazard early warning-monitoring and avoidancerelocation in the area.
