| 摘 要： | 本文从系统理论出发,运用层次分析法(AHP)对影响泥石流危险性的相关因子进行分析,从泥石流的物源条件、地形地貌条件、和诱发因素中选取10个指标作为评价泥石流危险性的评价因子,构建了泥石流危险性评价的层次指标体系,并对各参与评价因子的权重作了计算,建立起泥石流危险性评价模型.最后通过实例验证,评价结果与实际情况有较好的一致性,因此,运用层次分析法进行泥石流危险性评价是实用和有效的.

| Abstract: | From the view of system theory,this paper uses the analytic hierarchy process(AHP) to analyze the factors which affect debris flow then ten factors from conditions of debris flow material source,terrain conditions and predisposing factors are quantified to establishe hierarchy indicators system of debris flow risk assessment,and gives weight each factor.Finally,the evaluation results has a high relativity to the fact is verified by example test.Therefore,the use of AHP for debris flow risk assessment is pra... |
