摘要
根据评价区域的危险性评价和易损性评价矢量图层进行属性运算,得到了贺州市富川瑶族自治县重点调查区地质灾害风险性分区,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和易损性评价结果,将地质灾害风险性分为极高、高、中、低4个等级。
According to the vector layer of the regional risk assessment and vulnerability evaluation,the paper obtained the risk zones of geological disasters in key investigation area in Fuchuan Yao Autonomous County in Hezhou City,while the visualization was achieved by GIS software.According to geological disaster risk assessment results and the vulnerability assessment results under different rainfall conditions(a decade rainfall condition,twenty years rainfall conditions,once every 50 years rainfall condition,a once-in-a-century rainfall conditions),the risks were divided into four grades(extremely high,high,medium and low).
