摘　　要： 泥石流沟谷是一个复杂的“模糊”系统,它是由多种因素构成,应用模糊综合评判法,选取了7个因子作为泥石流危险度划分的主要关联因子,并且运用了灰色系统关联度分析法确定了评价因子隶属度,对泥石流沟谷危险程度进行了判别,其评价结果显示了模糊评判法具有较高的判别准确度,为进行有效的灾害防治提供了可靠的科学依据。 The ditch valley of debris flow is a complicated fuzzy system, it is formed by many kinds of factors, fuzzy comprehensive evaluation method is used and seven factors were chosen as the dangerous degree of main related factors dividing the debris flow,the related degree of analytic approaches of the grey system is used to confirm and appraise the factor and is under the jurisdiction of degree and get a better way to judge dangerous degree of debris flow. The evaluation result show that fuzzy comprehensive evaluation method has higher discrimination accuracy and has offered reliable scientific basis for preventing and curing the calamity effectively.
