选取地形地貌、地质、气候、水文、植被和人为活动6个致灾指标,人口密度、工程设施和土地利用3个承灾因素,将二级模糊综合评判模型用于单体滑坡风险的评估.先在同类因素间进行初级评判,再利用初判的结果进行类间的二级评判.以青川窝前滑坡为例进行了二级模糊综合评判的实现,得出危险度为0.49,易损性度为0.067,危害度为0.033. 更多还原

【Abstract】 The two-level model of the fuzzy comprehensive evaluation is used to assess single landslide risk,selecting six hazard indexes:topography,geology,climate,hydrology,vegetation,human activities.and three vulnerability factors:population density,engineering facilities,land use information.Preliminary evaluations are proceeded in the same type.Then the senior evaluation is proceeded with the results of preliminary evaluations between the all types.Taking QingChuan Woqian landslide as an example,disc... 更多还原
