摘　　要：根据2008～2012年海宁市地面水水质指标的监测数据，采用单因子评价法、综合污染指数法、有机污染综合评价法和R型聚类分析法，对海宁地表水现状进行了评价。结果表明，海宁地表水的主要污染因子为氨氯、总磷，其中氨氮为首要污染因子；近年来，海宁地表水水质一直处于中度污染状态，其中2008～2009年水质略有好转，然而近3年来却一直小幅波动。各监测指标中，NH3-N和CODMn、CODCr与CODMn、TP与CODMn、CODCr和NH3-N呈现明显的相关性。According to the monitoring data of water-quality indexes in Haining during 2008 - 2012, several methods （single factor evalua- tion, comprehensive pollution index and comprehensive evaluation of organic pollution） were used to evaluate the water quality in Haining. The results showed that the main pollution factors of Haining surface water were NH3-N and TP, while NH3-N was the primary one; although the water quality improved during 2008 -2009, but in the last three years it appeared to be a slight fluctuation. NH3-N and CODM. had a sig- nificantly positive correlation, so did CODer and CODMn , TP and CODMn, CODcT and NH3-N.
