摘要
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.
