摘要
以2021年2月(冬季)和8月(夏季)乐清湾海域的调查数据为基础,分析调查海域浮游动物群落结构的时空变化特征。结果表明:乐清湾海域浮游动物群落结构具有明显的季节变化,8月(夏季)浮游动物种类数、生物量、丰度和物种多样性指数均明显高于2月(冬季),2个季节群落结构的差异主要来源于水母类和浮游幼虫2个类群;在空间分布上,乐清湾内湾海域浮游动物群落结构与中湾、外湾海域显示出一定的差异性,外湾至内湾海域浮游动物生物量和丰度总体呈降低趋势,中湾海域和外湾海域的空间差异则较小,这表明乐清湾华能玉环电厂和浙能乐清电厂这2个电厂温排水未对整个乐清湾海域浮游动物群落结构产生较大影响,其影响可能主要集中在紧邻温排水口的海域。
The spatial and temporal variation characteristics of the zooplankton community structure in the surveyed waters were analyzed based on the survey data from Yueqing Bay waters in February(winter)and August(summer)2021.The result showed that the zooplankton community structure in the Yueqing Bay waters exhibited significant seasonal changes,with the number of zooplankton species,biomass,abundance and species diversity index being significantly higher in August(summer)than in February(winter).The differences in community structure between the two seasons were mainly attributed to two taxa(medusa and planktonic larva).In terms of spatial distribution,there were certain differences in the community structure of zooplankton in the inner bay area of Leqing Bay compared to the central bay and outer bay areas.The biomass and abundance of zooplankton in the outer bay to inner bay areas generally showed a decreasing trend,while the spatial differences between the central bay and outer bay areas were relatively small.This indicated that the thermal drainage of the two power plants(Huaneng Yuhuan Power Plant and Zheneng Leqing Power Plant)had not have a significant impact on the community structure of zooplankton in the entire Leqing Bay area,its impact may mainly be concentrated in the sea area adjacent to the warm discharge outlet.
