摘　　要：以云南省瑞丽市为研究区,基于GIS空间分析功能,选取高程、坡度、坡向、距断裂带距离、降雨等评价指标,用信息量模型和确定性系数模型进行地质灾害易发性评价,通过ROC检验评价模型精度,确定瑞丽市地质灾害易发性分区。Takeing the Ruili in Yunnan Province as the study sample,based on GIS spatial analysis function,eight evaluation indexes,such as elevation,slope,slope aspect,distance from fault zone and rainfallare selected to evaluate the susceptibility of geological hazards with information model and certainty factor model respectively.The accuracy of the model is evaluated by ROC test to determine the results of the susceptibility zones of geological hazards in Ruili City.
