对白花三叶草、沙棘、柽柳3种植被不同配置方式缓冲带对径流水中固体颗粒悬浮物的净化效果进行了研究。结果表明草本缓冲带对SS的净化效果明显,可净化约82.81%的SS。3块样地沿程截流污染物效果为:草本带>灌木带≈小乔木带。通过土壤抗侵蚀能力的评估,草本可提高0～20cm土层的抗剪切能力。灌木可提高20～40cm土层的抗剪切能力,乔木可提高20～55cm土层的抗剪切能力
The purification effect of solid particle suspended solids in runoff water was studied by using different configuration buffer zones of three kinds of vegetation, including white clover, seabuckthorn and tamarisk. The results showed that the herbicidal buffer had an obvious purifying effect on SS and could purify about 82.81% SS. Three samples along the river interception pollutants effect: Herb zone> Shrub zone ≈ small tree belt. Through the evaluation of soil anti-erosion ability, the herb can improve the shear resistance of 0 ~ 20cm soil layer. Shrubs can improve the shear resistance of 20 ~ 40cm soil layer, and arbor can improve the shear resistance of soil layers of 20 ~ 55cm
