摘要
本文将可能遭受泥石流灾害的受灾体划分为 1 7类 ,总结了各类受灾体的受害方式 ,提出了破坏损失率的概念和计算方法 ,用以确定受灾体遭受泥石流灾害损害的强度 ,并以云南东川市尼拉姑沟为实例进行了泥石流堆积区灾害破坏损失评价。
The paper divides possible disaster parts of debris flow into 17 types, then it sums up affected ways. It also points out the concept and methods of damaged rate so as to define the strength of affected by debris flow, and it evaluates the losses in debris flow areas taking Ni La Gu gully ,Dong chuan city , Yun Nan province as example.
