摘　　要：通过对乐清湾春、夏、秋、冬（2007～2008年）4个航次的调查，分析研究了乐清湾养殖区富营养化现状和变化趋势。研究结果表明，乐清湾水域营养盐含量十分丰富，全年无机磷、无机氮均超四类海水水质标准。基于8个监测站点的有机污染指数（A值）和富营养化指数（E值）的计算结果，发现整个乐清湾水体污染已达到严重污染程度。According to the investigation data obtained from four cruises in spring, summer, autumn and winter from 2007 to 2008 in Yneqing Bay, the eutrophication status and the variable trend were studied. The results showed that there was abundant nutrient in the area. Both inorganic nitrogen and phosphorus were beyond the fourth sea water quality standard throughout the year. Based on the organic pollution index （A） and eutrophication index （E） at eight monitoring sites, it was found that the whole waters in Yueqing Bay was in the serious pollution condition.
