| 摘 要： | 细沟侵蚀是土壤侵蚀的重要方式之一，但定量研究困难很大。本文设计并完成了一系列小规模细沟侵蚀冲刷试验，研究细沟侵蚀过程中的动力学规律。试验结果表明了一些细沟侵蚀的趋势性规律，也反映出其中存在较强的随机性。通过分析试验数据，得到了细沟宽度及过水断面湿周与流量和坡度的经验关系，并发现湿周与它们的关系更为密切。

| Abstract: | Rill erosion is one of important erosion manners on the slope, while it is difficult to study quantitatively. This paper designed and finished a serial of small scale scouring experiments to study the dynamics in this process. The results of these experiments show some tendency of the dynamic performance in the process, and there is also high randomness in it. Some empirical relations between the rill width or wet perimeter and discharge and slope are presented through the data analysis. The relation about wet perimeter is found more notable. |
