摘　　要：根据 1 998年 1 1月到 2 0 0 1年 5月对湛江港湾海域 6期的监测结果 ,初步探讨了该海域环境因子的变化特征和营养水平。结果表明 ,该海域水质处于高氮状态 ,pH、SS、DO和CODcr的含量符合GB30 97- 1 997第二类海水水质标准 ;DIN和油类超过第二类海水水质标准 ;DRP含量的逐年增高 ,湛江港湾海域目前已处于中度富营养化水平阶段。According to six surveying results in the seawater of Zhangjiang Port bay from November,1998 to May ,2001 the variation feature of environmental factors and eutrophication level of the seawater is discussed.The results show water quality of the area is rich in nitrogen. The contents of pH?SS?DO and CODcr are coincident with the second kind of seawater quality standard of GB3097-1997,and the contents of DIN and Oil are above the second kind of the standard.The contents of DRP is raised year by year.The water area of Zhanjiang Port bay is at the stage of medium eutrophication level.
