摘要
泥石流灾害是清水河流域最具破坏性的地质灾害类型。在自然状态下,地质地貌是该区泥石流形成的基本因素,降雨是泥石流暴发的激发因素,而人类各种不合理经济活动是泥石流促发因素.本文采用灰色理论方法进行泥石流与各种相关因素的关联度分析,并对该区未来泥石流发展的趋势及危害目标的危害度作了预测。
ud-rock flow is the most destructive type of geological disasters in the drainage area of the Qingshui River.In natural condition,the basic factor of mud-rock flow generation is the geological morphostructure;the excitation factor of mud-rock flow explosion is precipitation;and the facility factor of mud-rock flow is various human unreasonable economicactivities.Using the grey theory,the association analysis between the mud-rock flow and various correlation factors has been done,and a prediction of the development trend of mud-rock flows and the dangerous degree of the dangerous objectives are carried on.
