| 于2008年8月对湖南省西洞庭湖区40个典型养殖水体的浮游植物和水质理化指标进行了调查与分析。结果表明，40个养殖水体中共发现浮游植物67属101种，优势种类为铜绿微囊藻（Microcystis aeruginosa）、银灰平裂藻（Merismopedia glauca）、卷曲鱼腥藻（Anabaena circinalis）、水华鱼腥藻（Anabaena flos-aquae）、小席藻（Phormidium tenue）、十字藻（Crucigenia apiculata）、二形栅藻（Scenedesmus dimorphus）、四尾栅藻（Scenedesmus quadricauda）、集星藻（Actinastrum hantzschii）、卯形隐藻（Cryptomonas ovata）、羽纹脆杆藻（Fragilaria pinnata）、简单舟形藻（Navicula simplex）、尖针杆藻（Synedra acus）。浮游植物平均密度高达3．19×10^7个／L，变动范围9．46×10^4～1．32×10^9个／L。浮游植物密度与蓝藻密度存在良好的相关性，相关系数达到0．940（P〈0．0001）。Shannon—Wiener多样性指数（H＇）的变化范围为1．00～3．74。利用浮游植物细胞密度和多样性指数作为水体状况评价指标，初步评价表明，对于人工养殖水体而言，采用半精养模式的水体污染程度相对最轻。 |

| In Augest 2008, the phytoplankton and water quality in 40 aquacultural waters were investigated and analyzed in West Dongting Lake Area. A total of 67 genera and 101 species of phytoplankton were detected, of which Microcystis aeruginosa, Merismopedia glauca, Anabaena circinalis, Anabaena flos-aquae, Phormidium tenue, Crucigenia apiculata , Scenedesmus dimorphus , Scenedesmus quadricauda , Actinastrum hantzschii , Cryptomonas ovata , Fragilaria pinnata, Navicula simplex and Synedra acus were dominant. The average cell density of phytoplankton was 3.19 x 107 cells/L （9.46×10^4～1.32×10^9cells/L）. There was a significant correlation between cell densities of phytoplankton and cyanobaeteria （R = 0. 940, P 〈 0. 0001 ）. The Shannon-Wiener diversity index （H＇） ranged from 1.00 to 3.74. Water quality assessment was calculated by using diversity index and cell density of phytoplankton. It was indicated that semi-intensive aquacultural waterbodies were polluted lightly, compared with the other three kinds of aquacuhural waterbodies. |
