通过对大巴山泥石流形成和发育过程的研究,从侵蚀机制的角度,将其分为坡面侵蚀、沟谷侵蚀、复合侵蚀三种基本的侵蚀类型,并进一步分析了不同影响因素在各类泥石流发育中所起的作用,认为:坡面侵蚀型泥石流的发育与植被关系最密切;沟谷侵蚀型泥石流的发育对暴雨的依赖性最大;复合侵蚀型泥石流的发育与沟岸的不稳定有很大关系。最后,针对性地提出了大巴山区各类泥石流的防治重点。
Through the research on the formation and development of debris flow in Daba Mountain, from the perspective of erosion mechanism, it is divided into three basic erosion types: slope erosion, valleys erosion and compound erosion. Furthermore, the influences of different factors on the development of various debris flows , It is considered that the development of erosion-type debris flow is the most closely related to vegetation; the development of erosion-type debris flow is most dependent on rainstorm; the development of composite erosion-type debris flow has a great relationship with the instability of ditches . Finally, put forward the prevention and control of all kinds of debris flow in Dabashan area.
