长白山旅游区泥石流灾害研究

长白山旅游区为泥石流灾害频发地段，从地貌形态来看，其主要类型为山坡型泥充，其形成条件主要包括三个方面：区内广泛分布的倒石堆为泥石流的形成提供了主要物质来源，陡峭的地形提供了动力条件，丰富集中的降雨是诱发因素，这三个条件相互影响，缺一不可。分析表明，本区泥石流的空间分布规律与倒石堆的发育状况密切相关。

Research On the Debris Flows Hazard in the Tourist Area of Changbai Mountain

The tourist area of Changbai Montain is a place where debris flows happen frequently. According to the geomorphologic conditions of debris flow activity, the principal type is hillslope type of debris flows. Its forming conditions are mainly as follows: wide range distributing talus is the material source, and the steep topography and plenty of rainfall are respectively the dynamic and inductive factors. Not a single one of these conditions can be dispensed with. Finally, it can be concluded that the spatial distribution of debris flow is interrelated with the developing condition of talus.
