| 摘 要： | 2011年9月对长江中下游的4个草型清水湖泊(龙感湖、梁子湖、斧头湖及保安湖)的浮游植物群落进行了调查,共检出浮游植物7门231种,浮游植物主要由蓝藻、硅藻和绿藻组成.4个湖泊均处于中营养状态,出现的主要浮游植物有窝形席藻、肘状针杆藻、小席藻、小型黄丝藻等.运用典范对应分析(canonical correspondence analysis,CCA)对调查范围内的每个湖泊所有采样点的主要浮游植物与8个环境因子关系进行研究.结果表明,pH值和总磷是影响长江中下游4个典型草型湖泊浮游植物群落分布的主要环境因子. |

| Abstract: | The phytoplankton communities in 4 macrophtic lakes (Longgan Lake, Liangzi Lake, Futou Lake and Baoan Lake) in Middle-Lower Yangtze Plain were investigated in September 2011, and 7 phylum and 231 species of phytoplankton were detected in the waters. The results indicated that phytoplankton was mainly composed of Cyanophyta, Bacillariophyta and Chlorophyta. The four lakes were mesotrophic. And the main phytoplankton was Phormidium foveolarum, Synedra ulna, Phormidium tenu and Tribonema minus. The relationships between the distribution of phytoplankton and environmental factors in each sampling site were studies by canonical correspondence analysis. The results demonstrated that pH and Total phosphorus are the key factors for the distribution of phytoplankton communities in 4 typical macrophtic lakes in Middle-Lower Yangtze Plain. |
