中文摘要：

为了解春季浒苔暴发区浮游动物的生态特征，于2009年3月在南黄海浒苔暴发区14个站位采集浮游动物样品，探讨了该水域浮游动物的种类组成、丰度和优势种，并结合环境因子对浮游动物的生物多样性及群落结构进行了分析。本航次共鉴定各类浮游动物34种，桡足类和水螅水母为最主要浮游动物类群，分别占浮游动物成体种类数的41．2％和14．7％；中华哲水蚤、小拟哲水蚤、羽长腹剑水蚤和强壮箭虫以及浮游幼虫中的海蛇尾长腕幼虫和海胆长腕幼虫数量上占据优势。浮游动物的平均丰度为428．6ind／m3，与同期历史数据相比有所降低。根据各站位间浮游动物组成的相似程度和地理分布，将研究海区浮游动物划分为山东沿岸低盐组群、苏北沿岸低盐组群和黄海中部高盐组群。

英文摘要：

Based on the survey of former green tides Outbreak area of the South Yellow Sea in March, 2009 （spring）, this survey was carried out to examine the species composition, abundance, biomass and biodiversity of the zooplankton community. 54 taxa were identified totally, including 20 pelagic larvae. Copepod was the most dominant component of the crustacean. The species number of pelagic copepod and medusa represented 41.2% and 14.7% of total species richness, respectively. The average abundance of zooplankton was 428.6ind/m3. Comparing with that of the same period （spring） in 2001 in this area, the present average abundance was lower. Six dominant zooplankton taxa were recorded in this survey： Calanus sinicus , Paracalanus parvus , Oithona plurni f era , Sagitta crassa , Ophiopluteus larvae, Echinopluteus larvae. Based on the species composition and the abundance of the zooplankton, the 14 stations can be divided into three groups： Shandong neritic community, Subei neritic community and the South Yellow Sea central community.
