Phytoplankton community structure in the Guangzhou Sea was investigated from May 2003 to May 2004.The results show that there were 209 species in total, representing 89 genera.Among these, diatoms (122 species, representing 41 genera) accounted for 58.4%, and Skeletonema costatum was the most dominant species.The species richness and abundance of phytoplankton decreased from the inside of estuary to the outside of estuary, where there were high specie ruchness and density of phytopla -nkton due to the influences of dilution water.During the investigation, the annual average density of phytoplankton was 4.11×105cells·L-1, and shows double abundance peaks annually.
