| 摘 要： | 从有机物含量、营养物质含量等较重要的化学指标进行分析,降雨与各种不同下垫面径流水质污染程度差异较大,天然降雨、绿地径流与屋顶径流水质相对较好;但是雨水径流有明显的初期冲刷作用,污染物集中在初期的数毫米雨量中.

| Abstract: | Based on the analysis of important chemical indexes such as organic substances and nutrient contents, it is found that the pollution degree of the rainfalls and the runoff at different underline surfaces vary from one to another. The pollution by the rainfall and by the runoff from urban green land and roofs is comparatively light. But the rainfall and runoff has obvious effect of flushing at the initial stage and most of pollutants just concentrate in the first few millimeters of rainfall. |
