| 摘 要： | 通过复合坡面人工模拟降雨径流冲刷试验,研究了2种雨强下4种下垫面模式的坡面径流调控效应,从产流时间、侵蚀量、径流量以及泥沙含量等方面分析了径流调控的机理。结果表明:帕特草+PAM是一种理想的措施,其坡面径流量和侵蚀量均最小,较裸地对照(CK)分别提高了93.02%和98.13%,其次是帕特草+地孔,PAM+地孔;单纯在裸地上打地孔的坡面径流调控效果较裸地对照效果不明显。坡度对不同下垫面复合措施的影响甚微,而降雨强度对其影响却极为显著。坡面雨水的集蓄利用复合措施与水土保持综合治理模式改变了坡面的小地形状况,增加了植物(作物)覆盖度,加大了降水的入渗速率和数量,对黄土高原的水资源有效利用具有理论指导作用。

| Abstract: | Some tests have been done to simulate manual rainfall runoff washout on slope compound,and to study on runoff adjustment effect under the condition of 2 kinds of rainwater intensity and 4 pieces of measures,to analysis runoff principal from runoff time,erosion and sediment amount.The preliminary experimental research results are shown as: Pater and PAM is a ideal measure due to minimal runoff and erosion comparison with the same slope antitheses,increased 93.02%,98.13%,repectively,the following measures are... |
