摘　　要：选取三种不同透水路面,利用天然雨水进行模拟降雨实验,分析研究了其对雨水径流污染物的消减情况.当降雨强度为1.71,mm/min和0.70,mm/min,降雨历时分别为60,min和20,min时,对实验数据进行分析.分析表明:透水路面对雨水径流污染物的削减效果与透水路面结构、降雨强度、降雨历时、雨水径流水质有关,且透水砖和透水草皮砖路面对雨水径流污染物的消减效果最好;当降雨强度小时,三种透水路面对雨水径流污染物的削减效果较好.Simulated rainfall experiments are made by selecting 3 different permeable pavements, and the result of reducing pollutants in city rainwater runoff is analyzed. When the rainfall intensity is 1.71 mm/min and 0.70mm/min, it is shown that the reduction of stormwater runoff pollutants is related to the structure of permeable pavement, rainfall intensity and duration of rainfall, and water quality of stormwater runoff. The removal efficiency of pollutants by permeable brick and permeable turf brick is best. When the rainfall is small, the removal efficiency of pollutants by 3 different permeable pavements is quite good.
