摘　　要：采用高通量测序技术对2017年10月鄂东南典型湖泊龙感湖、太白湖和武山湖的超微型真核浮游生物群落组成及其与环境因子的关系进行了研究。结果显示,龙感湖、太白湖和武山湖均处于富营养化状态,TBH2和WSH3测站可能暴发了局部硅藻水华。三湖中检测到的主要类群为9门2纲2目,分别为:硅藻门、隐藻门、绿藻门、双并鞭虫目、纤毛虫门、金藻门、隐真菌门、甲藻门、壶菌门、领鞭虫目、卵菌门、硅鞭藻纲和网粘菌纲。硅藻门、隐藻门和绿藻门是三湖的超微型真核浮游生物优势类群,浮游生物组成在湖泊间的空间差异并不显著。研究表明,溶解氧、电导率、氧化还原电位和氨氮是龙感湖、太白湖和武山湖超微型真核浮游生物群落的主要环境影响因子。This paper adopted high-throughput sequencing technology to investigate the community composition of eukaryotic ultraplankton and its relationship with environmental factors in October 2017 in Lake Longgan,Lake Taibai,and Lake Wushan,which are typical lakes in Southeast Hubei.The results showed that water eutrophication was obvious in Lake Longgan,Lake Taibai,and Lake Wushan and localized diatom blooms may have occurred at the TBH2 and WSH3 stations.Major groups detected in the three lakes were nine phyla,two classes and two orders,which were Bacillariophyta,Cryptophyta,Chlorophyta,Bicosoecida,Ciliophora,Chrysophyta,Cryptomycota,Dinophyta,Chytridiomycota,Choanoflagellida,Oomycetes,Dictyochophyceae and Labyrinthulomycetes.Bacillariophyta,Cryptophyta and Chlorophyta were the dominant eukaryotic ultraplankton in the three lakes,and the spatial differences of plankton composition among the lakes were not significant.The correlation analysis indicated that dissolved oxygen,conductivity,oxidation-reduction potential and ammonia nitrogen were the main environmental impact factors of the eukaryotic ultraplankton community in Lake Longgan,Lake Taibai,and Lake Wushan.
