| 摘 要： | 选取了一次泥石流（可能）最大冲出量,泥石流发生频率,流域面积,主沟长度,流域相对高差,流域切割密度,24h最大降雨量,松散固体物质储量8个因素作为泥石流危险性的影响因子.运用灰色关联分析法,选取云南蒋家沟泥石流作为参考系列,通过比较泥石流沟之间的相似性来预测其危险性.最后,用于西藏八宿泥石流危险度评价,结果表明此方法是可行的.

| Abstract: | In this paper, eight factors including the maximum expulsion amount of debris flow once, occurrence frequency, drainage area, length of the main gully, relative altitude, cutting density, maximum quantity of rainfall in 24 hours and amount of loss solid matter, are chosen as the influence factors of debris flow hazard, by means of the gray correlation method, taking Jiangjiagou debris flow, Yunnan Province as an example, through the similarity of debris flow gullies to forecast their dangerous degree, lastly Basu debris flow in Tibet verified the feasibility of this method. |
