摘    要:本文根据2000~2002年6个航次的调查资料,对长江口及邻近水域的渔业环境质量进行全面研究及变动趋势分析。研究结果表明,长江口及邻近水域营养盐含量十分丰富,约90%无机氮是以硝酸盐形态存在。该水域主要受营养盐、重金属及有机物的污染。其中杭州湾水域受污染程度最为严重。长江口及邻近水域浮游植物初级生产主要受磷营养盐的限制。总的来说,长江口及邻近水域渔业环境质量正呈逐步下降趋势。

关 键 词:长江口  渔业环境  浮游植物  初级生产  磷营养盐  污染

Abstract:Based on the monitoring result of fisheries environmental quality in the Changjiang River estuary and adjacent East China Sea, the results showed that the concentration of nutrients was very high and about ninety percent of inorganic nitrogen were nitrate nitrogen in the water area. The water area was mainly polluted by nutrient salts, heavy metals and organic matters. Hangzhou Gulf was the most polluted water area among three water areas such as Changjiang River estuary, Hangzhou Gulf and Zhoushan archipelago. The primary production of phytoplankton may be limited by the concentration of phosphate. In general, fisheries environmental quality of the Changjiang River estuary and adjacent East China Sea has been declining gradually.
Keywords:Changjiang River estuary and adjacent East China Sea  fisheries environment  exceeding standard rate
