浙江舟山港近岸海域富营养化现状分析

Analysis of Eutrophication along the Coastal Waters in Zhoushan Harbor

文章于2011年2月~2012年1月对浙江舟山港（6个码头）近岸海水中COD、无机氮（DIN）和磷酸盐（DIP）污染现状进行了1年的监测（每月一次）,以此分析和评价舟山港近岸海域富营养化水平。结果表明：在被调查的6个码头中,水体营养等级基本为极度富营养化,这说明舟山港近岸海域处于严重的富营养化状态;富营养化状态指数中COD占优势,其次为DIN,这两者起到了绝对性作用,而且该海域的藻类生长基本上是受氮限制的。

Based on the investigation data of COD, inorganic nitrogen （DIN） and phosphorus （DIP） from February 2011 to January 2012, the paper dealt with the situation of the water eutrophication in the coastal waters of Zhoushan harbor （including 6 docks） in Zhejiang province. The coastal waters of Zhoushan harbor were in the serious eutrophication condition, and COD and DIN were the dominant compositions of eutrophication index. Furthermore, the coast was classified as N-limiting eutrophication level.
