摘　　要：以披碱草、高羊茅、紫穗槐、柽柳为试验材料,研究这4种植物不同配比方式构造的缓冲带对地表径流中的固体颗粒污染物、全氮、全磷的去除效果。结果表明,缓冲带前段栽植草本,中段栽植灌木,末段栽植小乔木,并在小乔木林下栽植草本的缓冲带类型(缓冲带3型)对径流中面源污染物的去除效果较佳,建议在实践中推广应用。The Elymus dahuricus, Festuca arundinacea, A morpha fruticosa, Tamarix as experimental materials, the apper studied the four plant different ratio methods to construct the buffer zone on the surface runoff in the SS, TN and TP removal effect. The results showed that buffer zone with planting herbaceous and planting shrubs in the middle and planting trees of the period, and under the small tree planting herbaceous （buffer zone type 3） on runoff non-point source pollutants removal effect was better, it was recommended for promotion in practice.
