摘要
白龙江流域地处青藏高原、黄土高原、四川盆地交接处,我国东西南北向地震带从此交汇通过,此处构造复杂、山高坡陡、沟谷深切、软岩广布,且多暴雨,是我国四大滑坡、泥石流灾害高发区之一。基于实地调查研究、并结合现有资料和研究成果,总结分析了白龙江流域滑坡、泥石流的分布特征、形成条件、成因机理、监测预警、防治措施等多方面进展及不足,推进该流域地质灾害研究,支持当地防灾减灾建设。
The Bailong River catchment is located in the intersection of Tibetan Plateau,Loess Plateau and Sichuan Basin.It is also the cross point of the east-west and north-south seismic zones.Due to complex geological structures,the region is characterized by steep slopes,high relative reliefs and deep incised valleys.Weak rocks,which are widely distributed,and heavy rainfalls made the region one of the four areas in China most severely affected by landslide and debris flow disasters.Based on the data from field investigation and on-going research projects,this paper deals with the characteristics of landslides and debris flows,and their genetic mechanisms.The management of monitoring and early-warning systems and hazard prevention in this region are also discussed,with the purpose to encourage further researches on geohazards and mitigation measures in the region.
