摘　　要：根据2010年椒江口海域3个季节的海洋调查资料,运用定量、定性方法,探讨该海域浮游植物、富营养化和赤潮之间的关系.自该海域共鉴定浮游植物81种,赤潮种35种,由于受椒江径流、浙江沿岸流、台湾暖流和上升流共同影响,浮游植物种类数、平面分布及优势种有明显的季节变化;最主要的赤潮优势种是旋链角毛藻(Chaetoceroscurvisetus)、中肋骨条藻(Skeletonema costatum)、具槽直链藻(Melosira sulcata)和琼氏圆筛藻(Coscinodiscusjonesianus);调查期间海域富营养化指标E值大于1,富营养化程度较为严重,但浮游植物群落结构较为稳定,多样性指数较高,并未发生赤潮.Phytoplankton,eutrophication and ride tide were investigated in three seasons of 2010 in the Jiaojiang Estuary,Zhejiang,China and the relationship between them was studied by qualitative and quantitative methods.There were a total of 81 species of phytoplankton,including 35 species of red tide algae in the estuary.There were apparent seasonal variations in numbers of species,horizontal distribution and dominant species due to comprehensive influences of Jiaojiang runoff,Zhejiang coastal upwelling and Taiwan warm current.The primary dominant red tide algae were Chaetoceros curvisetus,Skeletonema costatum,Melosira sulcata and Coscinodiscus jonesianus.During the investigation,serious eutrophication prevailed with eutrophication index（E） higher than 1,while community structure of phytoplankton was relatively stable with a high diversity index,and red tide did not occurred.
