为确定径流条件下坡耕地的侵蚀规律，采用不同流量对10°及15°坡的坡耕地进行径流冲刷试验。试验结果表明：坡面土壤的产流量、产沙量随流量、坡度的增大而增加，但增加幅度不同，流量及坡度越小，坡面的减流减沙效应越显著；相同流量、相同坡度下，产流量呈先增加后趋于平稳的趋势，产沙量呈先增加后减少最后趋于稳定的趋势。

In order to explore the erosion regularity of downhill farmland in the condition of runoff, it took different flow rate for 10 ° and 15 ° slope of cropland for runoff scouring experiment, to analyze the amount of runoff and sediment from each slope, the conclusion shows: Slope soil runoff and sediment yield were increased with the flow and slope, but the increments are different. Smaller flow and slope reduced the runoff and sediment of the slope more obvious. Under the same flow and slope, runoff, as time changes, was in-creased first, then leveled off, and the sediment yield was increased first, reduced later, then leveled off in the end.
