摘　　要：选取淮南城区6种不同下垫面,研究了自然降雨和径流雨水随降雨历时和径流历时的水质变化,并探讨了降雨强度对初期径流水质的影响和径流污染物之间的相关性。研究表明:初期自然降雨和初期径流污染较为严重,随着降雨历时和径流历时的延长,自然降雨和径流雨水污染程度均逐渐降低并趋于稳定,且径流雨水中SS与其他污染物之间具有良好的正相关性;不同下垫面径流雨水水质具有一定差异,屋面径流雨水明显好于路面径流雨水;降雨强度对初期径流水质具有较大影响,降雨强度越大,初期径流雨水污染越严重。The paper studied water quality change of natural rainfall and rainwater runoff with rainfall and runoff duration respectively and discussed the influence of rainfall intensity on early runoff water quality and the relationship between the runoff pollutants by selecting six different underlying surface in urban area of Huainan. The result showed that the early natural rainfall and runoff pollution were both relatively serious,the pollution levels of natural rainfall and rainwater runoff were gradually reduced and tended to be stable with rainfall and runoff duration. SS and other pollutants in runoff had a good positive correlation,and the water quality of rainwater runoff from different underlying surface had a certain difference. The water quality of roof runoff was better than the road surface runoff,and rainfall intensity had great influence to the early runoff water quality and the early rain runoff pollution was more serious with greater rainfall intensity.
