摘要
由于影响泥石流危险性的因素很多,定性和定量因素关系复杂,导致各因素的权重很难确定,且目前尚无完善的泥石流危险性评价体系。以新疆某泥石流为例,通过将影响泥石流因子的定性和定量因素有机结合,选取了10个影响因子作为评价指标,采用层次分析法确定了各评价指标的权重,并基于可拓学理论确定了泥石流沟危险性等级,评价结果与实际调查相符,表明本文所用方法具有可行性。
Because there are many factors influencing debris flow risk, and the relationship between qualitative and quantitative factors is complex, it is difficult to determine the weight of each factor. Moreover, the system of the debris flow risk assessment is not perfect. Taking risk evaluation of debris flow in Xinjiang as an example, combination of the qualitative and quantitative factors for influencing debris flow, this paper selects the 10 factors as evaluation indexes. The analytic hierarchy process （AHP） is used to determine the weight of each evaluation index, and risk level of the debris flow gully is obtained by using extension theory. The evaluation results are consistent with the actual survey, which indi- cates that the proposed method is feasible.
