摘　　要：通过室外人工模拟降雨的方法,得出了在不同坡度、降雨量和降雨强度时,不同植被覆盖度的流失泥沙颗粒组成、黑土地表的径流量以及土壤含水量的相应变化。Based on the outdoor artificial rainfall methods it was reached that different vegetation coverage of the loss of sand particles corresponding, the black surface runoff, and soil moisture changes in different slope, rainfall and rainfall intensity.

关 键 词：黑土流失 人工模拟降雨 降雨量 降雨强度 坡度 东北
