摘要
本文根据2004～2006年闽东沿岸（26°30′00″～27°10′00″N，119°59′40″～120°33′00″E）暖水季节6个航次的浮游动物调查资料，比较分析研究了调查区暖水季节的浮游动物种类组成、数量分布和优势种变化．3年调查结果表明，该海域出现的浮游动物种类数分别为151、127和144种，种类组成变化不大，强额孔雀哲水蚤（Pavocalanus crassirostri）、小拟哲水蚤（Paracalanus parvus）等在各航次中都占据明显优势地位；调查期间该海域的浮游动物群落面貌以近岸暖水种和外海热带种为主，这两类生态类群的浮游动物构成本海区的主要优势类群；生物量分布不均匀，总体平面分布趋势是：北高南低，从沿岸到近海，浮游动物生物量随盐度上升而下降；优势种分布极不均匀，聚块现象明显．
Based on the zooplankton samples from 6 cruises in Mindong coastal waters,East China Sea （26°30′00″ - 27°10′00″N, 119°59′40″ - 120°33′00″E） in May and August 2004, July and August 2005, May and August 2006,this study analyzed the species composition, the distribution of biomass, as well as the changes of dominant species. The data show little changes of species composition among 2004,2005 and 2006 with Pavocalanus erassirostris and Paracalanus parvus as the main dominant species in each cruise. The total numbers of species in 2004,2005 and 2006 were 151,127 and 144, respectively. The distribution of biomass was not homogeneous which was higher in the north than in the south with a tendency of decrease from the coast to the open sea. The distribution of dominant species was not even either, with significant assembling phenomenon. Water temperature and salinity were still the main factors affecting the biomass and distribution of zooplankton.
