Seasonal succession of phytoplankton functional groups and its driving factors in Haizi Reservoir
摘要
Abstract
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.关键词
