摘　　要：本文运用模糊层次分析法对四川省汶川县锄头沟泥石流进行了危险性评价,选取流域面积、相对高差、主沟长度、流域切割密度、最大冲出方量、流域内主要岩性、24 h最大降雨量等7个影响因子为指标,对锄头沟泥石流进行危险性评价。结果表明,锄头沟泥石流危险等级为高度危险,为当地泥石流灾害防治工作提供理论参考依据。In this paper,Fuzzy Analytic Hierarchy Process(AHP)was used to evaluate the risk of mudslide in Zhutougou Valley,Wenchuan County,Sichuan Province.7 influencing factors such as basin area,relative height difference,length of main ditch,watershed cutting density,maximum outflow volume,main lithology in the basin,and maximum rainfall in 24 hours were selected as indicators to evaluate the risk of mudslide in Zhutougou Valley.The results show that the danger level of debris flow in Zhutougou is highly dangerous,which provides theoretical reference for the local debris flow disaster prevention.
