摘要
泥石流活动性评价是进行泥石流危险性评价的重要内容之一。本文采用处理非线性问题的有力工具——灰色系统理论中的关联度分析法,建立了泥石流活动性评价的方法,并用此方法,以云南蒋家沟为参考序列,对云南的6条典型泥石流沟进行活动性评价,评价结果与实际的情况较吻合。并应用云南保山王官屯沟和云南怒江州六库的芭蕉河沟做了检验,结果表明本方法是正确性可行的。
Activity evaluation is important in carrying out risk evaluation of debris flow. In this paper, taking Jiangjiagou as a reference series, the method of grey correlation has been used for the quantitative analysis of 6 typical debris flows in Yunnan province. The result agrees with actual condition. Then, it is proved to be correct by using two samples, Wangguantun gully and Bajiaohe gully.
