摘　　要：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。A series of pilot experiments of runoff pollution were conducted on riparian buffer strips covered with Agropyron cristatum （Linn.） Gaertn, Hippophae rhamnoides Linn, Tamarix chinensis. The results showed that the herb of purification buffer zone on the SS effect is obvious, can purify approximately 82.81% of the SS. The effect of cut-off pollutant was that Agropyron cristatum （Linn.） Gaertn Hippophae rhamnoides Linn ≈ Tamarix chinensis. Through the appraisal to the soil anti-etching power, the herb may enhance 0~20 cm soil layer anti-cutting ability, the bush 20~40 cm , the tree 20~55 cm.
