以位于北京市平谷区的北京海子水库为研究对象,以浮游植物功能群调查为基础,于2010年春、夏、秋三季对海子水库进行了生态调查;根据水库水环境特征,在北湖、南湖两个不同生境区域设置采样点,进行浮游植物水样采集,将3个季节中的浮游植物划分为16个功能群,利用典范对应分析方法,对同步取得的电导率、TN、TP、水温等环境因子与浮游植物功能群分之间的相关性进行分析。结果表明:2010年海子水库共鉴定出浮游植物74种(包括变种),分属于6门37属。浮游植物种类组成为:绿藻门20属45种,占种类总数的60.82%;蓝藻门7属11种,占14.86%;硅藻门5属8种,占10.81%;裸藻门2属7种,占9.46%;甲藻门2属2种,占2.70%;隐藻门1属1种,占1.35%。浮游植物丰度春季(801.67×104个/L)<秋季(3589.17×104个/L)<夏季(13806.53×104个/L),三季均值为6065.78×104个/L。代表性功能群的季节演替为:春季(J/Xph/P/C)→夏季(Tc/S2/P/C)→秋季(X1/C)。 TP、水温、电导率是海子水库浮游植物功能群演替的主要驱动因子。

Taking Beijing Haizi Reservoir in Pinggu district, Beijing, as the research object, based on phytoplankton functional group survey, ecological investigations were carried on in spring, summer and autumn, in 2010.According to the characteristics of the water environment in the reservoir area, two sampling sites were set in different ecological regions of northern lake and southern lake to collect the phytoplankton water samples.The phytoplankton in three seasons is divided into 16 functional groups.Using canonical correspondence analysis method, correlation analysis between environmental factors, including electrical conductivity, total nitrogen, total phosphorus and water temperature, and phytoplankton functional groups was conducted.The results showed that:74 phytoplankton species ( including mutations) are identified, which can be sorted into 37 genera and 6 phyla. The phytoplankton can be classified into: 45 genera and 20 species of Chlorophyta, which occupy 60.82%; 7 genera and 11 species of Cyanophyta, which occupy 14.86%;5 genera and 8 species of Bacillariophyta, which occupy 10.81%; 2 genera and 7 species of Euglenophyta, which occupy 9.46%; 2 genera and 2 species of Pyrrhophyta, which occupy 2.70%;1 genera and 1 species of Cryptophyta, which occupy 1.35%.Phytoplankton abundance increased from spring(801.67×104 ind/L)<autumn(3 589.17×104 ind/L)<summer(13 806.53×104 ind/L).The average value in the three seasons is 6065.78 ×104 ind/L.The dominant functional groups of the seasonal succession:Spring ( J/Xph/P/C ) → Summer ( Tc/S2/P/C ) → Autumn ( X1/C ) .Total phosphorus, water temperature and electrical conductivity are the main driving factors of phytoplankton functional groups succession in Haizi reservoir.
