摘　　要：根据2002和2003年年水质监测数据和历史资料,着重分析和评价了上海市金山三岛海洋生态自然保护区海域营养盐含量水平及其变化趋势。结果表明:营养盐(DIN和PO4 P)含量均超Ⅳ类海水水质标准,超标率达100%。与1990年建区前相比,营养盐污染更为严重,海域富营养化程度加剧。最后对金山三岛自然保护区的海域环境现状成因进行了探讨,并对其科学保护管理提出了几点建议。Based on the monitoring datum of sea water quality in the Jinshan Three-Islands Marine Ecological and Natural Conservation Area in 2002 and 2003, the emphasis on analyzing and assessing in the present condition and change tendency of the environmental quality was done. The results showed that the overall environment quality was at the level of heavy pollution, in especially, the nutrients seriously exceed the standard. Inorganic nitrogen and phosphate meanly exceed grade 4 seawater quality standard. Contrasting with historical datum in 1990, the pollution degree of nutrients became more and more seriously, and the eutrophication was severeous. Lastly the causes of present marine pollution are discussed, and some suggestions are proposed for the scientific protection and management.
