摘    要:根据2009年11月份大潮、小潮时期对奉贤附近海域进行的浮游生物生态调查资料,对大、小潮时期浮游动物的种类组成、密度与生物量分布、生物多样性及优势种的生态特征进行了比较分析。结果表明,大潮时浮游动物密度比小潮大,而浮游动物的种类数、生物量、生物多样性比小潮时低,大潮时优势种真刺唇角水蚤(Labidocera euchaeta)和火腿许水蚤(Schmackeria poplesia)的优势度(Y≥0.02)及其所占的数量比例高于小潮,优势种虫肢歪水蚤(Tortanus vermiculus)的优势度及其所占数量比例明显低于小潮。海洋浮游动物对潮汐变化的生态响应强烈。

关 键 词:浮游动物群落  潮汐运动  生态响应  奉贤近海

Abstract:Based on the data collected in the offshore area of Fengxian during the spring tide and neap tide in November 2009, we analyzed the species composition, biological density, biomass distribution, biodiversity and ecological characteristics of dominate species of zooplankton. Results show that the zooplankton density during spring tide is higher than that during neap tide, while the number of zooplankton species, biomass and biodiversity during spring tide are less than those during neap tide. The dominance ( Y≥0. 02) of Labidocera euchaeta and Schmackeria poplesia and their proportion of species number during spring tide are higher than those during neap tide, while Tortanus vermiculus shows an opposite result. Marine zooplanktons have strong ecological response to tidal variation.
Keywords:zooplankton community  tidal movement  ecological response  offshore area of Fengxian
