| 摘 要： | 目的]了解巢湖浮游生物群落结构特征。方法]以巢湖为研究对象,分析巢湖全湖水体生源要素空间分布特征,监测巢湖浮游植物和浮游动物群落组成特征及多样性。结果]巢湖氮磷比仍较适宜蓝藻生长,巢湖水域共鉴定出7门42属93种浮游植物,其中绿藻门为优势种(50种),浮游植物密度在1.48×10~7~17.44×10~7cells/L,且浮游植物群落结构不稳定,易受外界环境影响;浮游动物4门35属70种,其中轮虫种类数最多,占浮游动物总种类的45.71%,巢湖浮游动物多样性比较丰富,群落结构稳定性好。结论]研究结果为巢湖生态恢复提供了基础数据。

| Abstract: | Objective] The aim was to understand community structure characteristics of plankton in Chaohu Lake.Method] We investigated water quality for Chaohu Lake.Simultaneously,we investigated the community structure of phytoplankton and zooplankton,including plankton composition,cell density and their biodiversity.Result] The ratio of N/P was suitable to the growth of blue-green algae,and we identified 7 phyla,42 genera and 93 species for phytoplankton in Chaohu Lake,and Cryptophyta was the dominant species(50 species).Phytoplankton cell density in Chaohu Lake ranged from 1.48×107 cells/L to 17.44×107 cells/L,and the phytoplankton community structure was unstable,which was affected by other environmental factors.Simultaneous,there were high richness biodiversity for zooplanktonin Chaohu Lake,including 4 phyla,35 genera and 70 species,and we observed rotifer was the dominant species,which contributed to 45.71% of zooplankton in Chaohu Lake,but the phytoplankton community structure was stable.Conclusion] These results would provide the basic data and novel ideas for ecological restoration. |
