我国的水土流失面积大,范围广,各地的立地条件差异很大,水土流失的形式更是复杂多样,重力侵蚀十分严重,其在流域产沙中所占的比例很大,进行重力侵蚀研究具有重要的理论意义与现实价值。该文在回顾前人研究的基础上,将重力侵蚀分成崩塌、滑塌、滑坡、溜坍、泥石流侵蚀5种类型,其中崩塌侵蚀又分为9种型,滑塌侵蚀3种型,滑坡侵蚀9种型,溜坍侵蚀5种型,泥石流侵蚀3种型,即重力侵蚀共分为5种类型、29种型;并在此基础上给出了重力侵蚀5种类型的定义。
Due to the large area and wide range of soil and water loss in our country, there are great differences in site conditions across the country. The forms of soil and water loss are more complicated and diversified. Gravity erosion is very serious. The proportion of soil erosion in the basin is very large. Important theoretical and practical value. On the basis of reviewing the previous studies, the paper divides the gravity erosion into five types: collapse, slump, landslide, slump and debris flow erosion. The collapse erosion is divided into 9 types and 3 types of slump erosion. Landslide erosion 9 kinds of types, 5 types of slip erosion and 3 types of debris flow erosion, that is, gravity erosion is divided into 5 types and 29 types. Based on this, five types of definitions of gravity erosion are given.
