摘　　要：对成都市交通型、生活型、餐饮型和商业型四种不同功能区道路冲洗水径流的中pH值、COD、SS、TN、TP、NH_(3)^(-)N、动植物油和Pb等进行检测,通过对采样结果进行相关性分析和主成分分析,探究不同功能区道路冲洗水径流的污染特征,并进一步分析其污染源,为成都市道路冲洗水径流污染的控制提供科学依据。结果表明,交通型、生活型、餐饮型和商业型四种不同功能区道路冲洗水中COD、SS、TN、TP和NH_(3)^(-)N没有显著差异性,表明其污染源相似。交通型和生活型道路冲洗水总体污染程度较轻,但交通型道路冲洗水中的Pb污染最重;餐饮型和商业型道路冲洗水总体污染程度较重,主要受除机动车以外的人类活动干扰较大。The pH,COD,SS,TN,TP,NH_(3)^(-)N,animal and vegetable oils and Pb in the road flushing water runoff from four different functional areas in Chengdu City,namely,transportation,living,catering and commercial,were examined,and the correlation and principal component analyses were conducted to explore the pollution characteristics of the road flushing water runoff from the different functional areas and to further analyze the sources of pollution,so as to provide a scientific basis for the control of road flushing water pollution in Chengdu City.Through correlation analysis and principal component analysis,we investigated the pollution characteristics of road flushing water runoff in different functional areas,and further analyzed its pollution sources to provide scientific basis for the control of road flushing water runoff in Chengdu.The results showed that there were no significant differences in COD,SS,TN,TP and NH_(3)^(-)N in the road flushing water from the four different functional zones,namely,transportation,living,catering and commercial,indicating that the sources of pollution were similar.The overall pollution level of traffic-type and living-type road flushing water was less,but the Pb pollution in traffic-type road flushing water was the heaviest;the overall pollution level of restaurant-type and commercial-type road flushing water was heavier,which was mainly disturbed by human activities other than motor vehicles.
