摘要
泥石流危险度评价的准确性不仅是影响未来灾害学整体综合评价的要素之一,也是社会经济发展的要求之一。本文对甘肃省莲麓水电站评估区内8条泥石流沟,采用模糊层次分析法建立了泥石流危险度评价模型,从分析形成泥石流的物质、地形地貌、气候、土地使用情况和地质构造等方面,选取12个评价因子,定量的进行泥石流危险度评价。评价结果与实际吻合,表明模糊层次分析法用于泥石流沟危险度评价是科学可行的。
Veracity of debris flow dangerous degree assessment is one of essential in comprehensive assessment of disaster science, and is one of the desires in socio-economic development. This paper establishes the model of debris flow dangerous degree assessment with fuzzy analytic hierarchy process method from five aspects: substance, landform, climate, geological condition and soil use, and twelve estimate factors, to evaluate eight debris flow ravines in Lianlu Hydroelectric Station assessment section of Gansu Province. The result is consistent with chy process method to evaluate debris flow dangerous the actual, and it shows scientific and feasible with fuzzy analytic hierardegree.
