摘　　要：以湖南省为例 ,分析了滥伐森林 ,坡地复垦 ,缺乏环境意识的工程建设等人类活动方式与土壤侵蚀的关系 ,以及水土保持效益。认为局部地区土壤侵蚀面积增加且强度增大 ,水土侵蚀方式改变 ,重力侵蚀加剧等土壤侵蚀特性的改变 ,完全是人类活动方式对土壤侵蚀所产生的负面效应。而加强水土保持环境建设 ,增强良好的环境意识则可控制土壤侵蚀 ,保护水土保持成果。The relation between human activity way and soil erosion is analyzed where Hunan is taken as an example. Deforestation and reclamation of steep slopes have resulted in serious environment problems. In some regions the area affected by soil erosion is enlarging, and the erosion is being intensified. To enhance peoplYe′s environment consciousness is very important to the control of soil erosion, and the consolidation of the results of water and soil conservation.
