| 摘 要： | 为揭示南方红壤丘陵区水土流失地质成因规律和模式，促进水土流失精准治理，选择福建长汀县开展地质背景与水土流失关系研究。结果表明:岩性对水土流失侵蚀速度、侵蚀剧烈程度、水土流失发育阶段等具有控制作用；地形坡度和部位、节理裂隙对水土流失程度具有重要影响；区内不同岩性不同地形部位风化壳-土壤分布具明显的规律性。建议长汀县进一步依据地质背景优化水土流失治理布局，优选水保植物和种植方式，优化茶果园等坡地农业开发项目。

| Abstract: | In order to reveal the geological causes and patterns of soil erosion in the red soil and hills of the south, and promote the precise management of soil erosion, the relationship between geological background and soil erosion was selected in Changting County, Fujian Province. The results show that rock has a controlling effect on the rate of soil erosion, the degree of intense erosion and the stage of soil erosion development. Terrain slope and site, throsing fissures have an important impact on soil erosion, which is manifested in the weathering shell-soil distribution of different rocky and different terrain sites. It is suggested that Changting County further optimize the layout of soil erosion control according to geological background, preferably water-protected plants and planting methods, and optimize agricultural development projects such as tea orchards. |
