基于GIS和本底因素贡献权重模型的区域滑坡危险性评价—以重庆市万州区为例
Regional landslide danger assessments based on GIS and the root factor contributing weight model: a case study of the Wanzhou District, Chongqing.

摘要: 滑坡危险性评价是滑坡风险管理的重要内容和基础，其结果的好坏直接影响到管理的成效。在目前全国还没有统一评价方法和体系的情况下，以重庆市万州区为研究区域，利用一种物理意义明确并且易于操作的评价模型——本底因素贡献权重模型，在GIS软件中进行滑坡危险性评价。经过检验符合实际情况：高危险度区占全区面积的22.3%；中危险度区占全区面积的40.7%；低危险度区占全区面积的37.0%；高、中危险度区所包含的滑坡个数占到全区滑坡总数的77.6%。

Abstract: Landslide danger assessment is the important content and basis of landslide risk management and its results will impact the effect of management directly. There is no unifying method or system of assessments of landslide hazards in China till now. In this paper, by taking the Wanzhou District, Chongqing Municipality, as the research target, the authors introduced the “root factor contributing weight model” to assess the landslide danger level, which has a definite physical meaning and is easy to operate, and accomplished the landslide danger assessment in the GIS software. The results accord with the actual conditions by test. The highly dangerous places cover 22.3% of the area of the whole district; the moderately dangerous places, 40.7%; and the low dangerous places, 37.0%. The number of landslides contained in highly and moderately dangerous places makes up 77.6% of the total number of landslides in the whole district. -
