The characteristics of phytoplankton community structure in the Pearl River Estuary were studied at the late stage of a Phaeocystis globosa bloom from November 30 to December 2, 2009. Totally 118 species of microalgae belonging to six phyla were identified in the study. Among them, 67 species belonged to Bacillariophyta; 33 species belonged to Chlorophyta; 6 species belonged to Dinoflagellate; 5 species belonged to Cyanophyta; 5 species belonged to Euglenophyta; 2 species belonged to Chrysophyta. During the investigation, the diameter of optical colonies ranged from 0.5～2.5 cm, with an average density of 1208 colonies·m-3; and the average density under microscopic observation reached to 675000 colonies·m-3. The sudden rising of temperature from the mid to end of November might be the key factor causing the bloom. The: accompanying dominant species during the bloom were Skeletonema sp., Aulacoseira granulata, Cylindrotheca closterium and Euglena tritella.
