“5.12”汶川地震导致震区泥石流沟的活动性增强,使得泥石流的危险性发生了变化。泥石流是由多种因素综合作用的结果,是一个复杂的“模糊”系统,选取7个因子作为泥石流危险性评判因子,运用模糊综合评判法,对龙池的8条泥石流沟进行危险度评价。评价结果与实际情况基本相符,表明将模糊综合评判法应用于泥石流危险度评价是科学的和可靠的。
“5.12 ” Wenchuan earthquake caused the activity of the debris flow ditch in the earthquake area to increase, making the risk of debris flow changed. Debris flow is a result of a combination of many factors. It is a complex “fuzzy ” system. Seven factors are selected as risk factors of debris flow. By using fuzzy comprehensive evaluation method, Evaluation. The evaluation results are basically in line with the actual situation, indicating that it is scientific and reliable to apply the fuzzy comprehensive evaluation method to the risk assessment of debris flow.
