| 摘 要： | 打虎沟泥石流位于越西县城，发育于越西县城以西，由西向东长约3km，流域面积约1．3km^2。由于汇水面积较小，固体碎屑物源储量不大，最大一次堆积量仅1万m^3，属于小型泥石流。但因其出口就在县城东边，居民密集，危害严重。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，综合打虎沟泥石流危险度评价（H单=0．388）和灾害的易损度评价（V单=0．98），运用自然灾害风险度模型，得出了打虎沟泥石流的风险度为0．38，为高风险泥石流沟。

| Abstract: | the debris flow in Dahu gully is on the east part of Yuexi County, it is 3 km long and the drainage area is only 1.3 km^2 , and the reserve of the deposit is less than 104 m^3 , which attributes to minitype. Nevertheless,the gully abut against the residential area, and threaten the community in the area. The risk assessment of the debris flow is analyzed on the base of assessment of hazard and vulnerability, and it is concludes that the risk degree of the debris flow is 0.38, which attributes to high risk degree. |
