| 摘 要： | 广东省境内的东江流域，土壤侵蚀呈不连续的块状分布，主要集中分布在风化壳高度发育的花岗岩低山丘陵区，同时土壤侵蚀分布受人类活动的影响较大。通过实地调查采样分析发现，土壤侵蚀多分布于阳坡，其中面蚀、沟蚀多集中分布于坡面中上部，侵蚀对坡面不同部位的土壤理化性状产生直接的影响。

The Characteristic of Spatial Distribution of Soil Erosion in Dongjiang Basin of Guangdong Province |
| |
| Abstract: | In Dongjiang Basin of Guangdong Province, soil erosion mainly exists in low mountains and rolling areas withserious weathered granite, and distributes discontinuously. The distribution of soil erosion is greatly impacted by human activities. Field investigation and sample analysis indicate that soil erosion mainly distributes on south slope, in which surface erosion and rill erosion concentrate at the middle and upper part of the slope. Erosion has direct influence on physical and chemical properties of soil in different parts of slope. |
