Assessment on Regional Debris Flow Hazardousness of Anning River Valley in Liangshan Prefecture,Sichuan
摘要
在对凉山州安宁河流域5个县市的泥石流灾害进行野外调查和资料收集的基础上
进行了以乡镇为单元的小区域泥石流危险性评价。评价结果表明:在研究区129个乡镇中
31个乡镇处于泥石流极高危险区
60个乡镇处于泥石流高度危险区
34个乡镇处于泥石流中度危险区
4个乡处于泥石流低度危险区;其中喜德县泥石流危险性最大
德昌县和西昌市次之
然后是冕宁县和会理县。
Abstract
Based on investigation in the field and data collection for debris flow hazard of Anning river valley in five counties of Liangshan prefecture
Sichuan.The paper has worked out dangerous degree assessment considering villages and towns as cells in the studied area.The results show that: in the total of 129 villages and towns
31 villages and towns belong to the area of extremely high hazardousness of debris flow;60 villages and towns belong to the area of high hazardousness of debris flow;34 villages and towns belong to the area of moderate hazardousness of debris flow;4 villages and towns belong to the area of low hazardousness of debris flow.Dangerous degree of debris flow hazards in Xide county is the highest;next Dechang county and Xichang city;then Mianning county and Huili Couty.
