摘　　要：2009—2013年选取春末、夏中、秋初3个季节对海河干流浮游植物群落进行了调查,共检出浮游植物8门92属181种,浮游植物主要由绿藻、蓝藻和硅藻组成。主要优势种为:绿藻门的四尾栅藻、小球藻、卵囊藻、月牙藻、卡德藻;蓝藻门的微囊藻、胶鞘藻、螺旋藻、颤藻、蓝纤维藻;硅藻门的小环藻、菱形藻、舟形藻;隐藻门的啮蚀隐藻、卵形隐藻。运用典范对应分析研究该水域各站点主要浮游植物与6个环境因子之间的相互关系,综合分析5年研究结果,总氮、总磷和pH值是影响海河干流浮游植物物种分布的重要因素。The phytoplankton community in mainstream of Haihe River was investigated in late spring, mid-summer and early autumn from 2009 to 2013, and 8 phyla,92 genera and 181 species of phytoplankton were detected in the waters. The phytoplankton was found to be predomninantly composed of Cyanophyta, Bacillariophyta and Chlorophyta, including Scenedesrnus quadricauda, Chlorella vulgaris, Oocystis sp. , Selenastrum sp. , and Caeteria sp in Chlorophyta; Microcystis sp. , Phormidium tenue, Spirulina sp. , Oscillatoria sp. , and Dactylococcopsis sp. in Cyanophyta;Cyclotella sp. , Nitzschia sp. , Navicula sp. in Bacillariophyta and Cryptomonas erosa, C. ovata in Cryptophyta. The relationships between the distribution of phytoplankton and environmental factors in each sampling site were studied by canonical correspondence analysis. The 5 year observation demonstrated that total nitrogen, total phosphorus and pH were the key factors for the distribution of phytoplankton communities.
