摘　　要：传输型植被浅沟作为低影响开发(LID)技术中分散型源头污染物控制措施得到了越来越广泛的应用。以深圳光明新区牛山公园内的植被浅沟为例,考察了暴雨条件下植被浅沟对污染物的去除效果及稳定性,并分析了其对径流峰值的削减效果。结果表明,传输型植被浅沟对峰值强度不同的暴雨表现出了不同的污染负荷削减效果,可有效去除径流雨水中的SS、COD、TP和NH+4-N,其去除率稳定性为NO-3-N>SS>COD>NH+4-N>TP。As one of the distributed source pollution control measures of LID technology, the conveyance swale has been more and more widely used. Taking the grassed swale in the Niushan Park of Shenzhen Guangming New District as an example, the removal efficiency of pollutants in the grassed swale and its stability under heavy rain were investigated, and the reduction effect of the peak runoff was also analyzed. The results indicated that conveyance swale had different pollution load reduction effect under heavy rains with different peak intensities, and the SS, COD, TP and NH^-_4 - N in the runoff could be effectively removed. The stability of the removal rate was ： NO^-_3 - N 〉 SS 〉 COD 〉NH^-_4 - N 〉 TP.
