摘    要:在澳门半岛选取土地利用为公园绿地和商住混合的2个分流制城市小流域.于2005-08~2005-11借助自动采样器进行流域出口5场降雨地表径流水质水量监测.结果表明,商住混合分流制小流域TN、TP、COD多场降雨平均浓度值分别超出国家地表水环境V类标准4倍以上.公园绿地小流域TN、TP均超出V类水标准2倍多.从降雨-径流过程污染物浓度历时变化看,2个小流域TN和TP呈现一定的初始冲刷现象.TSS与TN、TP的判定系数R2都在0.95以上,地表径流中水土流失与总氮总磷输出显

Abstract:Characteristics of pollutants from urban surface runoff were investigated.Two catchments with a seperated system in Macau were selected for sampling on rainfall events during the period of August to November,2005.Water quality parameters such as pH,turbidity,TSS,COD,TOC,TN,TP,Zn,Pb,and Cu were analyzed.The results show that the commercial-residential urban catchment shows high level of COD,TN,TP,and the park urban catchment has high TN and TP concentration.From the pollutograph analysis,the peak of TSS,TN,TP concentration appears in the first and the third sample respectively in ELH and YLF catchments,and then the pollutants concentration tend to decrease.Regression analysis between TSS and TN & TP in two urban catchments resulted in a high value(R2>0.95) of the coefficient of determination R2 indicating a close relationship between soil losses and nitrogen & phosphorus discharged from surface runoff.The profile of TSS and COD discharged from surface runoff relates greatly to the surface flow change,whereas the surface flow change has little influence on the profile of TN and TP.The heavy metals such as Zn,Pb and Cu fluctuate with the continuous input of vehicles during rainfall events.Pollutants such as TSS,TN,COD discharged from surface runoff depend greatly on the dry periods and storms intensity in such two urban catchments.
Keywords:surface runoff  urban catchments  Macau
