小黑山岛海域网采大型浮游动物群落特征季节变化及其与环境因素关系研究

海岛生态系统是一类特殊的海洋生态系统，本研究关注了小黑山岛海域网采大型浮游动物群落特征季节变化及其与环境因子之间的相互关系。小黑山岛位于山东省的庙岛群岛之中，处于黄渤海分界线之上，本研究基于小黑山岛海域2013~2015年8个航次的现场调查数据，鉴定出浮游动物36种，其中桡足类13种，浮游动物丰度变化范围为1.5~287.5 ind/m3，平均68.4 ind/m3，生物量变化范围为0.3~346.9 mg/m3，平均51.9 mg/m3，Shannon多样性指数变化范围为0.64~2.15，平均1.22，Pielou均匀度指数变化范围为0.41~1.00，平均0.76。主要优势种有中华哲水蚤、强壮滨箭虫等，典范对应分析（CCA）结果显示环境因子中水温（WT）、透明度（Tra）和盐度（Sal）等对浮游动物群落分布影响较大，冬季强壮滨箭虫对桡足类群落特征可能有重要影响。

Seasonal variations of net macrozooplankton community characteristics and its relationship with environmental factors of the sea area around Xiaoheishan island in China

Seasonal variations of net macrozooplankton community characteristics and its relationship with environmental factors of the sea area around Xiaoheishan island were investigated in the present study.Xiaoheishan island lies in the middle of the Miaodao Archipelago.It lies on the dividing line of the Yellow Sea and the Bohai Sea in China.From 2013 to 2015, 8 periods were included in this survey.A total of 36 species of zooplankton were identified.Among these species 13 species belong to copepods.The abundance of zooplankton ranged from 1.5 to 287.5 ind/m3, with an average of 68.4 ind/m3; the biomass ranged from 0.3 to 346.9 mg/m3, with an average of 51.9 mg/m3.the Shannon diversity index (H') ranged from 0.64 to 2.15, with an average of 1.22; the Pielou evenness index (J') ranged from 0.41 to 1.00, with an average of 0.76.The main dominant species in the sea area around Xiaoheishan island were Calanus sinicus and Aidanosagitta crassa etc.The results of the canonical correspondence analysis(CCA) applied to the environmental factors indicated that water temperature(WT), transparency (Tra) and salinity(Sal) significantly influenced the zooplankton community.And we also find out that Aidanosagitta crassa may has an important effect on the copepod in winter.
