| 摘 要： | 运用原型模拟径流冲刷实验，研究了黄土坡面侵蚀过程水流阻力的变化规律。坡度的这种作用在很大程度上是通过径流刷形成的侵蚀形态特征不同来体现的。

| Abstract: | Elow resistance change law of rill erosion process on lOess slope is studied in the paper through prototype experiment ofstimulation of runoff erosion. Not only flow resistance change extension in rill erosion on loess slopes is obtained but also thechange law Of resistance coefficient along with flow conditions studied on the basis of the experiment result. It should bestressed that slope gradient has dominant impact on the development trend of flow resistance. The role of slope is genealperformed to a great extent tluDugh the erosion landform features formed by mnoff scour. |
