鄂西清江流域滑坡崩塌致灾背景及成灾模式
Formation Background and Regular Pattern of Avalanches and Landslides of Qingjiang River Basin in Western Hubei Province
摘要
Abstract
The mountain area in western Hubei Province,mainly in Qingjing river basin,is one of landslide and avalanche prone regions in China.Based on the results of the geological disaster investigation in 1 1 counties of this area,including 2,276 landslides and 567 avalanches,the characteristics of development and distribution of these landslides and avalanches are summarized in this paper by the method of statistics,induction and analo-gy.At the same time the control effect of different hazard-cause factors was respectively analyzed,including geological structures,lithology combination,river evolution,human activities and rainfalls.According to the key controlling factor,the formation patterns of landslides can be sorted into 4 types of regular ones,i.e.rain-fall controlled type,box-shape (close-narrow shape)anticline controlled type,wide and gentle shape syncline controlled type,and reservoir water-level controlled type,and those of avalanches can be classified into 2 types of regular ones,i.e.wide and gentle shape syncline controlled type,and karst-pillar controlled type.At last it was inferred that the risk of 3 types of landslides and avalanches must be focused on and prevented in the study area.关键词
