| 摘 要： | 简要介绍了土壤侵蚀的基本特征,将土壤侵蚀过程概括为3个基本的动力学过程,即降雨导致的坡面产流过程、表面流对土壤颗粒的剥蚀过程,以及表面流的汇集和输沙过程。进一步对3个基本过程的基本内容和涉及的科学问题进行了分析和概括,并由此讨论了土壤侵蚀动力学研究的发展趋势。

| Abstract: | This paper simply introduced the basic characteristics of soil erosion on hillslopes, and summarized the three basic dynamics processes of soil erosion, including the process of runoff generation caused by rainfall, the process of sediment yield on hillslope by overland flow, and the process of runoff concentration and sediment transport on watersheds. Furthermore, the basic issues and key academic problems related to the three basic dynamics processes are analyzed summarily, and also the future trends of soil erosion dynamics are briefly discussed. |
