摘　　要：根据2003年至2005年调查资料,以霓屿岛海域、三盘港海域以及竹屿岛海域为代表对浙江洞头列岛海域的水体富营养化及其与赤潮的关系进行分析研究。结果表明,丰水期水体中营养盐含量明显高于平水期,霓屿海域和三盘港海域富营养化最为严重,无机氮是水质富营养化的主要因素。富营养化和营养盐的结构是2004年5月在洞头列岛海域发生的具齿原甲藻赤潮的物质基础和首要条件。The seawater quality in Dongtou Islands, Zhejiang was classified and assessed according to monitor date of seawater from 2003 to 2005. The results showed that the contents of the nutrients are greater in high flow season than in low flow season. The nutrimental level in the Niyu Island and the Sanpan Island are the highest, because the inorganic nitrogen in the waters is too high. The resuits also showed that the eutrophication and nutrients species in the seawater are. the matter bases and major conditions for red tide produced by algae in Dongtou Islands in May, 2004. The relationship of the algae growth and the contents of inorganic nitrogen and phosphorus are negative.
