摘要
[目的]监测山东省近岸海域浮游动物的生物特征.[方法]2015年春季在山东省近岸海域开展了浮游动物多样性监测,探讨其群落结构与水质理化因子的关系.[结果]共鉴定出浮游动物26种,种类组成以近岸低盐类群和广温广盐类群为主,兼有少量低温广盐类群,中华哲水蚤、腹针胸刺水蚤、双毛纺锤水蚤、强壮箭虫为优势种.[结论]群落结构各类指数站位间变幅较大,结合同步调查的水质理化因子相关性分析表明,硝酸盐和亚硝酸盐是影响浮游动物群落结构最重要的环境因子,而叶绿素a含量是影响浮游动物生物量最重要的环境因子.
Abstract
[Objective] To monitor the zooplankton species diversity in offshore marine areas of Shandong Province in the spring of 2015,and to discuss the relationship between community structure and physicochemical factors of water quality.[Result] A total of 26 species were collected,including coastal brackish water group,eurythermal euryhaline group and a small number of hypothermal euryhaline group.Calanus sinicus,Centropages mcmurrichi,Acartia bifilosa and Sagitta crassa were the primary dominant species.[Conclusion]The amplitude of the index varied significantly among sites.Analysis showed that nitrate and nitrite were the most important environmental factors affecting the community structure of zooplankton; while chlorophylla a was the most important environmental factor affecting the biomass of zooplankton.
