%X 为了研究团结水库浮游植物功能群季节演替特征及其影响因子，分别于2020年9月(秋季)、2021年5月(春季)、7月(夏季)对团结水库设置的5个采样点进行浮游植物采样分析，共鉴定出浮游植物6门，划分为16个功能群，分别为C、D、F、H1、J、L0、M、MP、N、P、S1、W1、W2、X1、X2、Y。团结水库浮游植物功能群季节变化呈现为M + P → M + Y → D + F + P + W1 + Y的变化特征。运用冗余分析(RDA)探究浮游植物功能群与环境因子间的关系，结果表明，团结水库浮游植物功能群受水环境因子影响较为显著，其中，水深(Depth)、透明度(SD)、pH值、总磷(TP)、氯离子(Cl<b>？</b>)、化学需氧量(COD<sub>Mn</sub>)是影响浮游植物功能群分布的主要环境因子。团结水库水体中透明度(SD)、总氮(TN)、总磷(TP)、叶绿素(Chla)等指标均远超水体富营养化最低标准，表明该水库呈富营养化状态。<br />
In order to study the seasonal succession characteristics and influencing factors of phytoplankton functional groups in Tuanjie Reservoir, phytoplankton samples were analyzed in 5 sampling sites in September 2020 (autumn), May 2021 (spring) and July 2021 (summer), respectively. Six phyla of phytoplankton were identified, and they were divided into 16 functional groups: C, D, F, H1, J, L0, M, MP, N, P, S1, W1, W2, X1, X2, and Y. The seasonal variation of the Phytoplankton functional group in Tuanjie Reservoir is characterized by M + P → M + Y → D + F + P + W1 + Y. Redundancy analysis (RDA) was used to explore the relationship between phytoplankton functional groups and environmental factors, and the results showed that the phytoplankton functional groups were significantly affected by water environmental factors, and the water depth (Depth), transparency (SD), pH, total phosphorus (TP), chloride ion (Cl？) and chemical oxygen demand (COD<sub>Mn</sub>) were the main environmental factors that affected the distribution of phytoplankton functional groups. The values of transparency (SD), total nitrogen (TN), total phosphorus (TP) and chlorophyll (Chla) in Tuanjie Reservoir were all higher than the minimum standards of eutrophication. These indicate that the reservoir is in an eutrophication state.
