摘要
///Serious debris flows occurred in Qingping Country in Mianzhu, Sichuan Province. This disaster was caused by both the 2008-5-12 earthquake and strong rainfall. In terms of characteristics, 7 features were presented, such as group occurrence in space, complexity in initiation process, long duration in occurring process, transitional chain in damaging process, large magnitude and disaster concealment. As discharged materials were less (about 10% to 50%) compared to the total source materials, debris flows will further occur with a higher frequency in Qingping Country.
