Abstract:[Objective] The susceptibility of geological disaster was evaluated, in order to provide a theoretical basis for geological disaster prevention in Luding County, Sichuan Province.[Methods] With the help of Google image interpretation, 279 potential geological disaster points such as collapse, landslides and debris flows were obtained. The evaluation index system was constructed from four aspects including topography, lithologic structure, meteorological hydrology, soil and land use(LULC). The weight of the factors is determined by the deterministic coefficient method, and the weighted information model was constructed by the information quantity method. Disaster vulnerability was assessed by the ArcGIS spatial analysis.[Results] The extremely high and high risk areas accounted for 13.54% and 26.49% of the total study area, respectively. A total of 225 geological disaster sites were located in the extremely high and high risk areas, accounting for 80.65% of the total sample disaster points. The test was performed by the offline area(AUC) of the receiver operating characteristic curve(ROC), and its value was 0.793, and the accuracy of the evaluation model was excellent.[Conclusion] The geological disasters in Luding County was classified, and the risk assessment results of the weighted information method were reliable.
