摘　　要：通过对上海理工大学校园区的不同材质屋面径流水质监测,以及对污染主要影响因素与污染程度的分析表明,屋面材料、降雨历时、降雨强度及降雨量等是雨水初期径流水质的重要影响因素。屋面径流水质的主要污染指标COD、SS、浊度随径流历时呈指数变化,并最终趋于稳定。稳定水质的SS、浊度不受铺面材料和降雨特性的影响,而COD则随铺面材料和雨强大小的不同而变化。By monitoring water quality and analyzing its influential factors and pollution lever of the runoff from different material roof of buildings in residence of University of Shanghai for science and technology,it indicated that the important influential factors were the roof materials,rainfall duration,rainfall intensity and volume etc.The main pollutant index COD,SS and turbidity changed with runoff duration for index equations and tending to steadily at last.The steady SS and turbidity were not affected by roof materials and rainfall properties,but the steady COD changed with the different roof material and rainfall intensity.
