三江平原湿地——虎林地区夏季浮游植物群落结构特征

Community structure characteristics of phytoplankton in Hulin of the Sanjiang Plain wetland

  • 摘要: 对三江平原湿地虎林地区水域的浮游植物群落结构进行了初步研究。在采集区域设置10个采样点,经鉴定共有133个浮游植物分类单位,隶属于8门10纲16目27科48属。该地区浮游植物群落组成以硅藻门(Bacillariophyta)、绿藻门(Chlorophyta)为主。各采样点浮游植物种类组成及细胞密度差异显著,采样点Ⅸ的浮游植物种类最丰富,采样点Ⅱ的浮游植物细胞密度最大。在三江平原湿地虎林地区发现了大量的β-中污指示种,经聚类和多维尺度分析评价,初步推断三江平原湿地虎林地区水域受到一定污染,呈中营养状态。

     

    Abstract: We examined the phytoplankton community structure in the Hulin area in the Sanjiang Plain wetland in July of 2014 with 10 sampling sites. We identified 133 taxa belonging to 8 divisions, 10 classes, 16 orders, 27 families, and 48 genera. They were predominantly Bacillariophyta and Chlorophyta. The phytoplankton species composition and abundance was significantly different at each sampling site. Most of the algae were found in the site Ⅸ. While the biomass in sites Ⅱ was greater than that of other sites. We found a large proportion of β-mesosaprobic-zone indicators. Meanwhile, cluster analysis and non-metric multi-dimensional scaling analysis showed that the water in Hulin wetland was of certain degrees of pollution, and the water was at the mesotrophic level.
