摘要
根据2015-2017年每年5-11月对莱州湾招远海域扇贝养殖区进行的水质调查数据,分析了该海域浮游藻类的空间分布、群落结构及年际变化特征。共鉴定浮游藻类7门138种,其中硅藻门最多(86种),在数量与物种组成上均占主要地位;浮游藻类密度、生物多样性指数和均匀度指数呈现明显的季节特征:藻类密度在5-6月和9-10月出现2次峰值,生物多样性指数为1.92~3.57,均匀度指数为0.44~0.87;浮游藻类生态类型以温带近岸种为主,其群落结构呈现出温带海域区系特征,物种较多且分布较均匀,群落结构较稳定。
According to the water quality survey data collected from the scallop culture area in Zhaoyuan coastal waters of Laizhou Bay from May to November during 2015-2017, we analyzed the spatial distribution, community structure and interannual variation characteristics of phytoplankton. The study identified 138 species of phytoplankton, among which 86 species were Bacillariophyta, that was dominant in respects of both quantity and species composition. The phytoplankton density, biodiversity index and evenness index showed obvious seasonal characteristics. Phytoplankton density were the highest in May-June and September-October. The biodiversity index ranged from 1.92-3.57, and the evenness index variation ranged from 0.44-0.87. Phytoplankton was mainly in temperate coastal ecological type and the community structure presented temperate floristic characteristics of sea area. There were many species of phytoplankton which distributed rather evenly, and the community structure was relatively stable.
