摘要
多宗隆哇泥石流沟位于青海省兴海县中铁乡,距茨哈峡水电站仅1km,流域面积为144.3km2,由于汇水面积大且物源较多,将对下游的茨哈峡电站造成威胁。运用泥石流风险评价理论,结合泥石流的危险度评价和易损度评价,综合多宗隆哇沟泥石流危险度评价(H单=0.50044)和灾害的易损度评价(V单=0.49),运用自然灾害风险度模型,得出了多宗隆哇沟泥石流的风险度为0.24,为中度风险泥石流沟。
The Duozonglongwa mud-rock flow gully with a drainage area of 144.3km~ is located at Zhongtie Township, Xinghai, Qinghai, about lkm from the Cihaxia dam. The risk degree of the debris flow is 0.24, belonging to middle risk degree. The prevention suggestions are made.
