通过现场调查与分析，采用GIS技术，提取了南窖沟小流域泥石流风险评价的因子，选取其中较为重要的10项评价指标，划分了各评价因子的危险性分区，利用ArcGIS平台及可拓学评价方法对南窖沟小流域进行了泥石流风险性评价。参考已有研究成果，对单因子的危险性及易损性进行赋值，通过栅格化数值运算及关联度的加权综合计算，获得各单沟泥石流危险度及流域内危险性和易损性分区图，得到了小流域风险性分区结果，为该小流域泥石流预警及防治提供了参考依据。

By means of the ifeld research and GIS analysis, the inlfuence factors of the debris lfow in Nanjiao were obtained, and ten of them were selected to evaluate the risk. The risk of debris flow was evaluated by ArcGIS and extension theory. The values of risk and vulnerability of each factor in this area were given based on the former research, through the computerization of ArcGIS raster and weighted correlation function, the risk degree by extension theory and risk distribution characteristics was obtained. The risk distribution was given by the superimposed calculating vulnerability and hazard degree, which can be a reference for early warning and prevention of this debris lfow.
