| 摘 要： | 本文从系统理论出发,基于可拓层次分析法(EAHP),利用可拓工程方法,在物元模型理论的基础上建立了泥石流危险性评价的物元模型,并采用层次分析法计算物元模型中各评价指标的权系数。然后对美姑河流域牛牛坝公路泥石流沟进行了评价,得到牛牛坝公路泥石流的危险性为中度危险。结果表明该方法为泥石流危险性研究提供了一条新的思路和手段。

| Abstract: | By applying matter-element theory,extension engineering method,the matter element model of the debris flow hazard was established in this paper.The stratification analysis method used to calculate weight aggregation of evaluating factors was proposed.Then the debris flow hazard of the Niuniuba along highways in the Meigu river basin was evaluated,and the debris flow degree of the Niuniuba was moderate risk.The results showd that the method for debris flow risk study could provide a new way and means for debris flow risk study. |
