摘　　要：为了探讨不同草本植被对坡面产流产沙的影响,在人工模拟降雨条件下,选择福禄考、佛甲草、蓝羊茅,设计坡度为10°;早熟禾、黑麦草、高羊茅,设计坡度分别为5°、10°、15°,进行试验研究。研究结果表明:不同草本植物均能有效降低土壤的产沙量与产流量,起到保持水土、修复生态的作用。相同草本,不同坡度下,坡度越大,产流、产沙、土壤侵蚀量越大,作用系数也越大。In order to explore the effects of different herbal vegetation on runoff and sediment yield on slope,under artificial simulation rainfall condition,the Annual phlox,Sedum lineare,Festuca glauca are selected to carry out experimental study with a design slope of 10°,and the Bluegrass,Ryegrass,Tall fescue are selected to carry out experimental study with a design slope of 5°,10°,15°,respectively.The results showed that different herbal plants could effectively reduce the runoff and sediment yield of soil sediment,and play a role in soil and water conservation and ecological restoration.For the same herb,under different slopes,the greater the slope,the greater the runoff yield,sediment yield and soil erosion,and the greater the action coefficient.
