摘要
根据2006年7月至2007年11月在大亚湾四个季节的浮游动物调查资料,分析了大亚湾浮游动物的种类组成、优势种、群落结构、丰度和生物量的时空变化以及环境对其影响。经鉴定共有终生浮游动物105种和阶段性浮游幼虫17个类群。与以往调查资料相比,部分优势种的优势程度顺序发生了改变。由于受到季风、环流和人类活动等的影响,大亚湾浮游动物有一定的分布特征,在大亚湾核电站和澳头养殖区附近桡足类和枝角类偏低,水母类丰度增加。
Based on the data obtained from the four cruises carried out from Jun.2006 to Nov.2007,the species composition,dominant species,abundance and biomass of zooplankton in the Daya Bay were analyzed.Furthermore,the relationships between its characteristics and variation of environmental were discussed.A total of 105 species of holoplankton and 17 groups of planktonic larva were identified.Compared with the data in the last two decades,some dominant species and the dominant sequence have changed.The zooplankton structure was separated in relation to monsoon,current and anthropological activities.The species of copepods and cladocera around the nuclear station and aqua-farm were low,and the abundance of medusa was high.
