摘要:
2012年1月和7月通过对广东省境内10座供水水库进行水生态调查,采集48个站点的浮游植物样品,对其进行浮游植物功能类群的划分及聚类分析.调查区共鉴定出8门104属207种浮游植物,主要分属于30个功能类群.聚类分析将这10座水库聚合为4个类型区,第一生态类型区包括南水和新丰江水库,以适应低营养环境的功能类群为主;第二生态类型区包括飞来峡、白盆珠和新丰江水库,主要以中营养型和广谱型为优势功能类群;第三生态类型区和第四生态类型区包括高州、公平、大水桥、鹤地和汤溪水库,其中高州和公平水库主要以富营养型和广谱型为优势功能类群,其它水库则以适应富营养环境的功能类群为绝对优势类群.上述4个类型区浮游植物优势功能类群差异较大,且与水质营养状态有良好的响应关系.

Abstract:
Ecological investigations on the community structure of phytoplankton in 10 large reservoirs of Guangdong Province, which played a great role in water supply, were conducted in January and July, 2012. A total of 207 species of phytoplankton were identified, belonging to 104 genera of 8 phyla, which were classified into 30 phytoplankton functional groups. According to the cluster analysis, the ten reservoirs were separated into four ecological regions. Ecological Region One included Nanshui and Xinfengjiang reservoirs, where dominant groups were Oligotropher-adaptive groups. Ecological Region Two included Feilaixia, Baipenzhu and Fengshuba reservoirs, where dominant groups were Mesotropher-adaptive groups and broad-spectrum groups. Additionally, Ecological Region Three and Four contained Gaozhou, Gongping, Dashuiqiao, Hedi and Tangxi reservoirs, where Gaozhou and Gongping reservoirs were characterized by Eutropher-adaptive groups and broad-spectrum groups, while other reservoirs were dominated by Eutropher-adaptive groups. The representative phytoplankton functional groups were significantly different among four regions, and corresponded well with water nutrient conditions.
Key words:  Phytoplankton  functional group  ecological region  large reservoirs
