| 摘 要： | 利用人工模拟降雨试验,在不同植被格局的坡面上,研究了坡面不同植被格局对入渗、产流产沙的影响,结果表明:在小雨强下,不同植被格局的稳渗率大小差别较大;随着雨强的增大,不同植被格局的稳渗率差别逐渐减小。五种不同植被格局在不同雨强下的坡面上都在五分钟内达到稳渗。五种植被格局坡面累积产沙量的差异随着雨强的增大而增大,说明不同植被格局的确能够影响坡面植被的减沙减蚀作用。

| Abstract: | According to the artificial simulation of rainfall experiment on different vegetation patterns slope face,this paper studied the effects of vegetation patterns to infiltration,runoff and sediment production.The results have shown that under light rain intensity,the stable infiltration rate were great difference with different vegetation,but with the increase of rain intensity,the difference of stable infiltration rate were gradually decresed.The five kinds of different vegetation slope face under different intensity total achieved stable infiltration in five minutes.The variations of accumulated sediment production on the slope with five different vegetation patterns will be added with the rainfall intensity increasing,which indicated that the different vegetation patterns will be remarkably effected the function of the sediment reduction on the slop. |
