| Abstract: | [中文摘要]：介绍了近10年来植物根系提高土壤抗侵蚀性机理研究进展。植物根系稳定表土层结构、提高土壤入渗性能和抗剪强度、增强土壤抗冲性的有效性机理是植被抵抗径流侵蚀动态过程及土壤侵蚀预报研究亟待加强的关键科学问题。
[英文摘要]： This paper reviewed the research progress of plant roots on improving the resistance of soil to concentrated flow erosion over the last decade. The importance of plant roots in stabilizing soil structure, increasing soil permeability, and intensifying the resistance of soil to concentrated flow water is increasingly being recognized. However, few studies have been conducted according to the effectiveness of root systems of different of woody, shrubs and grasses species in reducing concentrated flow erosion on the larger scales. The further research in this respect is urgently needed for prediction and control of concentrated flow erosion associated with safely, economic, and environmental management strategies. |
