| 摘 要： | 2016年10月11日在西藏波密县白龙沟地区发生一次大型泥石流灾害，经济损失严重，对居民生命财产造成了巨大威胁，有必要对该区进行泥石流灾害的易发性评价。基于白龙沟泥石流的流域特征和形成条件，共选取18个评价因子，采用模糊数学和权的最小平方法进行泥石流易发性评价研究。结果表明，白龙沟泥石流处于易发的状态，评价结果与实地调查结果比较吻合。

| Abstract: | A large scale debris flow broke out in Bailong Gully area on Oct. 11, 2016 causing severe economic loss and threat of lives and property. It is necessary to evaluate debris flow susceptibility of the area in the future. Based on the characteristics of the drainage area and formation condition of the debris flow we select 18 factors, fuzzy math and weighted least-square methods to evaluate the susceptibility. Result of the methods shows that debris flow in the area remains susceptible and is coincided with the field evidence. |
