摘要
根据定量计算结果,进行了贺州市富川瑶族自治县重点调查区地质灾害危险性分区,并通过GIS软件实现可视化.根据不同降雨工况下(十年一遇降雨工况、二十年一遇降雨工况、五十年一遇降雨工况、百年一遇降雨工况)地质灾害危险性评价结果,将危险性按极高、高、中、低四个等级.
Abstract
According to the quantitative calculation results,the geo-logical hazard zoning of the key survey area in Fuchuan Yao Au-tonomous County in Hezhou City was carried out,and the visual-ization was achieved through GIS software.According to the evalu-ation results of geological hazard under different rainfall condi-tions(rainfall once every ten years,once every twenty years,once every fifty years,and once every hundred years),the risk is classi-fied into four levels:extremely high,high,medium,and low.
