Abstract本文所指的东北地区,包括辽宁省,吉林省,黑龙江省,内蒙古自治区昭乌达盟、哲里木盟和呼伦贝尔盟。本区随着山区开发、建设的蓬勃发展,山地生态环境遭到不同程度地破坏,因而泥石流活动也日益加剧和发展,给国民经济和人民生命财产带来了重大损失,从而引起人们的极大关注。本文就本区的泥石流作一分析,供研究和防治工作参考。 
Other Abstract The debris flows in this region are distributed in low mountain region of southeast Liaoning, Changbai Mountains, hills in west Liaoning, Daxinganling and Xiaoxinganling, in which the debris flows are quite active in low mountains and Changbai Mountains.In this region, the natural factors are the basic reasons causing debris flows and the artificial factors are the reasons accelerating the occurrence of debris flows.The characteristics of debris flows of Northeast in China are. the frequency of the occurrence is lower and the scale is fairly large; the loose solid matter is mainly supplied by the gully-bed accumulation; the debris flows take place in large numbers (in groups ) and their formative conditions are distinctively combined.Investigation shows that it is certain that this region is an old debris flow region; their types are mainly microviscous or viscous mud-rock flows, and also a small number of water-rock flows. The activity and damaging degrees of debris flow are not only related to the natural factors, but also to the destroyed degrees of mountain environment
