环境要素的变化对浮游植物的群落结构和功能具有重要影响.为揭示洞庭湖南汉垸湖区浮游植物群落结构特征及其影响因素,分别于2017年11月(关泵封水期)和2018年6月(开泵放水期)在洞庭湖区典型堤垸———南汉垸进行了采样调查,并对调查区域内的浮游植物及主要水环境因子进行了系统监测和分析.结果表明: ①调查期间共检出浮游植物8门62属,主要隶属于绿藻门(Chlorophyta)、硅藻门(Bacillariophyta)和蓝藻门(Cyanophyta),浮游植物分布表现出较为显著的时间差异性,11月浮游植物的丰度为8.34×10~6~ 3.02×10~8 L-1,6月为1.13×10~6~ 2.04×10~7 L-1. ②Shannon-Wiener多样性指数(H')介于1.10~ 3.24之间,...

The variation of environmental factors has a significant impact on the community structure and function of phytoplankton. In order to reveal the characteristics of phytoplankton community structure and its influencing factors in water bodies of Nanhan Polder in Dongting Lake Area,samples were collected in Dongting Lake was collected for analysis in November 2017 (period of pump closed) and June 2018 (period of pump open). Meanwhile,the phytoplankton and the main water environmental factors were systematically monitored and analyzed in the study...
