摘　　要：根据2008年对广西北仑河口海域16个站位的海水铜、铅、锌、镉、砷、总铬、总汞、pH值、无机氮、活性磷酸盐和油类等11项污染因子的调查,采用单因子指数法和内梅罗指数法对研究区海水水质进行评价。结果表明,北仑河口海域海水水质污染较为严重,主要发生在春季和夏季,Pb和Hg为该海区的主要污染物,且海水存在富营养化问题(主要是氮),同时还有油类的污染威胁。According to the investigation of 11 sea water pollution factors （Cu, Pb, Zn, Cd, As, Cr, Hg, pH, inorganic nitrogen, active phosphate, and oils） in Beilun River Estuary （Guangxi province） in 2008, the single factor index method and the Nemerow index method were used to assess the sea water quality. The results showed that sea water quality pollu-tion in Beilun River Estuary were seriously. Pollution occurred mainly in spring and sum- mer. Pb and Hg were the major pollutants in study area, water eutrophication problem （mainly nitrogen） and threat of oil pollution existed.
