摘　　要：重点对2002—2006年湛江港湾水域的环境因子进行分析，讨论港湾水质状况，表层和底层无机氮、无机磷质量浓度的年际变化趋势，以及水体富营养化的形成与赤潮的关系。分析湛江港湾水体富营养化的成因。结果表明：湛江港湾水质状况较好，但氮、磷浓度都较高，且有逐年升高的趋势；赤潮产生除与水体富营养化、赤潮生物有关外，还包含诸多因素的综合作用。最后提出了控制水体富营养化和防止赤潮发生的具体措施。Through investigation of the environmental indices of coastal waters in the Port of Zhanjiang from 2002 to 2006, the water quality status, the annual variations of inorganic nitrogen and inorganic phosphorus concentrations in shallow and deep water, and the relationship between eutrophication and red tide are discussed. The causes of the eutrophication are also described. The results indicate that the water quality condition was good except for the high and increasing concentration of nitrogen and phosphorus, and the red tide is related not only with eutrophication and red tide organisms, but also with other factors. Finally, methods are presented for avoiding eutrophication and red tide.
