| 摘要: |
| 运用多元分析方法对安邦河湿地春、夏浮游植物群落进行划分,结果表明,两季节均可分为3个组群:(1)核心区组群,春季为绒毛平板藻-四角盘星藻群落,夏季为四角盘星藻群落;(2)边缘区组群,春季为梅尼小环藻-尖针杆藻群落,夏季为鱼腥藻-铜绿微囊藻-梅尼小环藻群落;(3)莲花池组群,春季为地中尖头藻群落,夏季为银灰平裂藻群落.各群落的种类组成、数量及多样性存在季节差异,与寒区环境因子季节变化相关. |

| Abstract: |
| Investigations on the phytoplankton were carried out at 10 stations in Anbanghe wetland, a type of cold regions swamp, in summer 2005 and spring 2006. Phytoplankton community classification was undertaken by multivariate analyses, such as cluster analysis and metric multidimensional scaling analysis (MDS).92 common species occurred in both seasons, and 37 taxa and 82 taxa were identified in spring and summer, respectively. In spring the average abundance was 95.26×104ind./L, and in summer was 268.45×104ind./L. Based on the calculation of Bray-Cartis similarity matrix according to species abundance compositions of each station, cluster and MDS analysis showed that three communities can be distinguished in both seasons:(i) the central community, in spring, was Tabellaria flocculosa-Pediastrum tetras community, and in summer was P. tetras community, (ii) the margin community, in spring, was Cyclotella meneghiniana-Synedra acus community, and in summer was Anabaena sp.-Microcystis aeruginosa-C. meneghiniana community, (iii) the lotus flower pond community and Raphidiopsis mediterranea community in spring, and Merismopedia glauce community in summer. Phytoplankton composition, abundance, and diversity of each community were different between spring and summer, and positively correlated to the change of environmental factors between seasons. |
