摘要
康乐县地处甘肃东南部,位于洮河流域下游,为黄土高原向青藏高原的过渡地带,是我国泥石流灾害最为严重的地区之一。本文以康乐县境内的20条典型泥石流沟为例,选定10个主要影响因子作为泥石流危险度评价的指标,依据层次分析法确定各因子的权重,并利用模糊综合评判法对其做出危险性评价。研究表明处于高度危险状态的泥石流沟多达11条,占到总数的50%以上,建议对其进行重点监测和防治。
Kangle County is located in the southeastern part of Gansu Province,located in downstream of the Tao River Basin,which is one of the most serious areas of debris flow in the transition zone of the Loess Plateau to the Qinghai-Tibet Plateau. This paper takes 20 typical debris flow gullies in Kangle County as an example and 10 major factors are selected as indicators of debris flow risk assessment. The weight of each factor is determined according to the analytic hierarchy process and the risk assessment is made by fuzzy comprehensive evaluation method. The results show that in a highly dangerous state of debris flow up to 11,more than 50% of the total,it is recommended to focus on monitoring and prevention.
