摘要
花岗岩风化壳的崩岗侵蚀,是华南地区土壤侵蚀最严重的类型,侵蚀严重阶段年平均侵蚀模数可达20～30万tkm^2。本文介绍了有助于崩岗地形发育的两个特性,论述了崩岗地形形成与土壤侵蚀过程、沟形沟系与侵蚀类型的关系,将崩岗侵蚀过程分为深切期、崩塌期、夷平期三个阶段,并阐明了各侵蚀阶段的特征。
The erosion subject to benggang (gully-slope collapse) in efflorescent shell, the most severe pattern of soil erosion in South China, suffers an annual erosion module for 200×10 3-300 × 10 3t/km2 in the most severe stage. It is presented two factors relative to the process of land form development, -and also discussed in this paper the relationships between landform subject to benggang and soil erosion, as well as gully systems and erosion patternsThe erosion process of benggang is devided into the deep-cutting period, the avalanche period and the degradation
period with the characteristics of each.
