Twelve cruises of phytoplankton survey were made in Guangzhou segment of the Pearl River estuary in 2008-2010.And 185 species of phytoplankton were indentified during the survey period.The dominant species were Skeletonema costatum and Melosira granulate & Melosira granulate v.angustissima,and they changed with an obvious seasonal succession.During the survey period,the average cell number of phytoplankton in Guangzhou segment of the Pearl River estuary was 5.51×105cells/L,and there were variation ranges among the yearly mean cell number.Through comparing the yearly mean Shannon-Wiener biodiversity index and Pielou evenness index of 2008,2009 and 2010,it was concluded that the eco-environment quality in 2010 was better than it in 2008 and 2009,and the phytoplankton community structure was more stable.After correlation analyzing,the result showed that the concentration of PO43--P was the main influence factors of the growth of phytoplankton in the survey estuary.
