重力侵蚀分类研究

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。

Analysis on Characteristics and Stability of the Palongzangbu Landslide Erosion

The Palongzangbu landslide with a big size, appeared some distortion in 1950’s, and began sliding in 1991. This paper dealt with the analysis of the formation and evolution of the Palongzangbu landslide, the characteristics and cause of formation of the landslide erosion, the characteristics of rock-soil body in landslide areas, and the analysis, calculation and evaluation of stability, and the evaluation on the possible catastrophe and the degree of erosion after landslide sliding.
