| 摘 要： | 为了解LID措施在实际应用中对雨水径流的控制效应，选取广州市天河智慧城透水铺装和绿地开展现场监测，在透水铺装和绿地上分别选取20场次和11场次降雨径流资料分析径流削减情况，在透水铺装和绿地上均选取2场次降雨水质资料分析污染物去除情况。结果表明:透水铺装和绿地的径流量削减率均随着雨前干旱期增加而上升，随着降雨历时、降水量和最大雨强的增加而下降；在降水量较小时，绿地的径流量削减率比透水铺装的大，在降水量较大时反之。雨前干旱期越久，地表累积的污染物越多，冲刷到雨水径流中的污染物越多，雨前干旱期越长的场次降雨的透水铺装和绿地雨水径流污染物质量浓度亦越高。

| Abstract: | In order to understand the control effect of low impact development(LID)measures on rainwater runoff in practical application, the permeable pavement and green land in the Tianhe Smart City of Guangzhou City are selected to carry out field monitoring. Twenty and eleven rainfall runoff data are separately selected to analyze runoff reduction in permeable pavement and green land, respectively, and two rainfall water quality data are selected to analyze pollution removal in permeable pavement and green land. It is showed that the runoff reduction rate of permeable pavement and green land is increased with the increase of antecedent dry period(ADP), while it decreases with the increase of rainfall duration, rainfall and maximum rainfall intensity. If the rainfall is small, the runoff reduction rate of green land is larger than that of permeable pavement, while the rainfall is large, the opposite is true. The ADP is the longer, the pollutants accumulated on the surface and washed into the rainwater runoff is the more, and the pollutant concentration of permeable pavement and green land rainwater runoff is the higher. |
