摘　　要：以贺州市平桂区为例,按地质灾害危险系数法进行定量计算,根据定量计算结果,综合考虑各影响因素,进行了贺州市平桂区地质灾害危险性分区,并通过GIS软件实现可视化。贺州市平桂区地质灾害危险性分区结果显示,高危险区总面积为712.92 km^(2),约占全区总面积的35.26%;中危险区总面积为960.44 km^(2)约占全区总面积的47.50%;低危险区总面积为348.63 km^(2),约占全区总面积的17.24%。Taking Pinggui District in Hezhou City as an example,quantitative calculation was carried out with the method of geological disaster risk coefficient.According to the results of quantitative calculation,the geological disaster risk zoning of Pinggui District in Hezhou City was conducted and visualized by GIS software.The zoning results in Pinggui District of Hezhou City showed that the total high risk area is 712.92 km^(2),accounting for 35.26%of the total area.The total medium risk area is 960.44 km^(2),accounting for 47.50%of the total area.The total low risk area is 348.63 km^(2),accounting for 17.24%of the total area.
