Abstract以横断山区的崩滑流山地灾害为研究对象,选取坡度、坡向、曲率、相对高差、岩性、断裂带密度和河网密度作为该区域山地灾害静态危险性的评价因子,采用频率比法计算了横断山区山地灾害静态危险度。在此基础上,重点考虑降雨因子对山地灾害危险性动态变化的影响,并基于灰色关联度法确定静态危险度和降雨因子对山地灾害动态危险性影响的相对权重,最后采用因子叠加法实现了横断山区山地灾害的动态危险性评价。相关研究成果对于横断山区的发展规划和山地灾害的防灾减灾工作具有重要指导意义。
Other AbstractThe mountain hazards such as collapses,landslides and debris flows in Hengduan mountain area are taken as research subjects,and slope,aspect,curvature,relative relief,lithology,fault density and drainage network density are taken as static evaluation factors of mountain hazards,using frequency ratio method to assess the static hazard of mountain hazards. On the basis,considering the dynamic influence of rainfall factor,the relativity analysis method is used to determine the relative weights of static hazard and rainfall factor. Finally,factors superposition method is used to realize the dynamic hazard assessment of mountain hazards in Hengduan Mountain area. The relevant research results have important guiding significance for the development plan and the prevention and mitigation of mountain hazards in Hengduan Mountain area.
