摘要
根据2013年6—7月在黄、渤海进行的大面调查,本文研究了以大型浮游生物网采集的浮游动物的种类组成、丰度、优势种、生物多样性,以及浮游动物丰度与环境因子的关系。本次调查共鉴定浮游动物87种,其中南黄海80种、北黄海33种、渤海49种。桡足类和浮游幼虫均为三个海区主要的优势类群。浮游动物平均丰度表现为渤海(1737.8 ind·m^(-3))>北黄海(1079.5 ind·m^(-3))>南黄海(699.0 ind·m^(-3))。浮游动物优势种共7种,其中三个海区所共有的优势种为小拟哲水蚤(Paracalanus parvus)、中华哲水蚤(Calanus sinicus)和强壮箭虫(Sagitta crassa)。根据Spearman相关性分析结果,底层海水温度为影响各优势种丰度分布的最重要环境因子。研究结果可为进一步探究中国近海浮游动物分布特征及其与海洋环境变化的关系提供基础数据。
Based on a large-scale survey conducted in Yellow Sea and Bohai Sea from June to July,2013,we studied the composition,abundance,dominant species and biodiversity of zooplankton,as well as the relationship between zooplankton abundance and environmental factors.A total of 87 zooplankton taxa were identified,80 in southern Yellow Sea,33 in northern Yellow Sea and 49 in Bohai Sea.Copepods and pelagic larvae were the dominant components in the surveyed sea areas.The average zooplankton abundance was the highest in Bohai Sea(1,737.8 ind·m^(-3)),which was followed by that in northern Yellow Sea(1,079.5 ind·m^(-3))and southern Yellow Sea(699.0 ind·m^(-3)).There were 7 dominant zooplankton species in the sea area.Among thethe dominant species,the shared in three sea areas were Paracalanus parvus,Calanus sinicus and Sagitta crassa.According to Spearman correlation analysis,the bottom seawater temperature was the most important environmental factor affecting the abundance distribution of all dominant species.Our results will provide basic data for further characterization of zooplankton distribution and its response to marine environmental changes in the costal seawaters of China.
