崩岗侵蚀是我国南方山区最重要的水土流失形式,崩岗侵蚀的治理是水土流失治理的关键。本文以广东省韩江上游五华县新一村为例,论述了我国南方山区花岗岩风化壳崩岗侵蚀的特点,分析了花岗岩风化壳崩岗侵蚀特别发育与花岗岩风化壳——土壤性质的关系。并探讨了采用生物措施和工程措施相结合的方法治理花岗岩崩岗侵蚀的效果。
Collapse erosion is the most important form of soil and water loss in southern mountainous areas in China. The management of collapsing erosion is the key to soil and water loss control. In this paper, taking Xin Yi Village, Wuhua County, upstream of Hanjiang River in Guangdong Province as an example, this paper discusses the characteristics of the collapse of granite weathering crusts in southern mountainous areas of China, and analyzes the relationship between granite weathering crust collapse erosion and granite weathering crust - soil properties . And explored the effect of using the combination of biological measures and engineering measures to control the collapse of granite.
