摘　　要：浮游植物功能群从生态学的角度,利用生态位原理为浮游植物划分归类,更好地阐述了浮游植物种间及其与环境的关系,为淡水生态系统研究中预测浮游植物群落发生、水体监测等提供了更为准确的依据.本研究于2015年4月及7月开展对上海市淀山湖春夏季浮游植物功能群组成及其影响因子的研究,分别将采集到的浮游植物归入相应的功能群.结果为,春季功能群(20个),分别为B、C、D、E、F、G、H1、J、Lo、M、MP、P、TB、TC、W1、W2、X1、X2、X3和Z;夏季功能群(17个),分别为B、C、D、F、G、J、Lo、M、MP、TB、TC、W1、W2、X1、X2、X3和Z.其中春季优势功能群为X2、X1、P、Lo和J,夏季优势功能群为X2、X1、P和Lo.RDA分析结果显示,影响淀山湖浮游植物优势功能群变化的主要环境因子是Kd、T、DO、σ和TP.From the perspective of ecology and by using the theory ot ecologmal nichlv, phytoplankton functional group has a better description about the relationship between phytoplankton and their environment, and provides a more accurate basis for freshwater system research about the composition of phytoplankton and water monitoring. This research of phytoplankton functional group composition and influence factor is carried out in spring and summer in 2015 in Shanghai Dianshan Lake, and phytoplankton were collected and respectively in the function of the corresponding group. The results for spring function group （20 in total） B, C, D, E, F, G, H1, J, Lo, M, MP, P, TB, TC, W1, W2, X1,X2, X3, and Z. Summer function group （17 in total） includes B, C, D, F, G, J, Lo, M, MP, TB, TC, Wl, W2, X1, X2, X3, and Z. Advantage function group for the spring is X1, X2 and, Lo, J; summer advantage function group is X2, X1, P, Lo. Through the analysis of the RDA, the main factor which has a great influence on phytoplankton advantages is Kd, T, DO, a and TP.
