| 摘 要： | 对高羊茅、紫穗槐、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(SS)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83.81%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。通过对土壤抗侵蚀能力的评估可知,草本可提高5～20 cm土层的抗侵蚀能力,灌木可提高15～30 cm土层的抗侵蚀能力,乔木可提高25～40 cm土层的抗侵蚀能力。 |
| 关 键 词： | 滨岸缓冲带 面源污染 抗侵蚀性 悬浮物 |

| Abstract: | A series of pilot experiments of runoff pollution were conducted to study the effect of suspended solids（SS） on riparian buffer strips covered with Festuca arundinacea,Amorpha fruticosa L,Tamarix chinensis.The results show that the purification effect of herbs in buffer zone to SS is obvious and approximately 83.81% of the SS purity could be achieved.The effect of cut-off pollutant was that： Festuca arundinaceaAmorpha fruticosa L≈Tamarix chinensis.Through the appraisal to the soil anti-erosion power,it is concluded that the herb might enhance 5～20 cm soil layer anti-erosion ability,the bush 15～30 cm,and the tree 25～40 cm. |
| Keywords: | buffer strips non-point pollution erosion resistance suspended solids(SS) |
