摘要
花岗岩风化壳的侵蚀是华南地区最严重的水土流失类型,而崩岗侵蚀则是其中最重要的侵蚀过程。本文主要通过调查、分析,论述了崩岗形成与演变的基本特点,剖析了崩岗侵蚀的内在机理及外部营力,从而揭示了广东省崩岗侵蚀的基本规律,并提出了相应的防治途径。
The erosion of granite weathering crust is the most serious type of loss of water and soil erosion inthe south of China,of which the erosion of slope disintegration is the essential process.In this paper,by means of investigation and analysis,the basic characters of forming and development are expoundedand the inherent mechanism and external force of erosion of slope disintegration are analyzed.Mean-while the erosion law of slope disintegration in Guangdong province is revealed.Further more the pre-vention approach is suggested.
