| 摘 要： | 淀山湖是上海市最大的淡水湖泊,属亚热带浅水湖泊.于2017年对该湖的浮游动物和水质参数进行逐月调查,并结合浮游植物群落数据,采用多元回归树模型(multivariate regression trees,MRT)和主坐标分析(principal coordinates analysis,PCo A)等方法研究了该湖浮游动物群落结构时空分布特征及其与环境因子的关系.结果表明,淀山湖浮游动物群落结构季节差异显著(P 0. 05),但仅在春、夏季节存在空间差异(P 0. 05),其他季节空间差异不显著(P 0. 05).水温、叶绿素a、氨氮以及蓝藻丰度是引起淀山湖浮游动物群落时空变化的关键性因子. MRT分析表明,当水温13. 07℃时,表现为冬季群落特征,当水温在13. 07～19. 57℃之间时,表现为春季群落特征;当水温≥19. 57℃时,叶绿素a浓度≥9. 03μg·L-1,则为夏季群落特征,而当叶绿素a浓度9. 03μg·L-1时,则表现为秋季群落特征.聚类分析将淀山湖浮游动物群落分成3个空间区域;春季时,当氨氮浓度1. 11 mg·L-1时,上游进水区(区域Ⅱ)浮游动物群落与其他两个区域有显著差异(P 0. 05);而夏季当蓝藻生物量≥2. 58 mg·L-1时,区域Ⅰ的浮游动物群落与其他两个区域有显著的空间差异(P 0. 05).
