Abstract: The species composition, distribution, and seasonal and annual variations in phytoplankton in artificial reef area of Haizhou Bay were studied by the data acquired from the cruises in February, July, October, 2003 and February,2004. The results showed that there were 2 phyla, 16 genera, and 36 （mostly warm in shore） species in phytoplankton collected in Haizhou Bay. The cells and species of Bacillariophyta （13 genera and 31 species）were absolutely predominant in the species composition, and follwed by Ceratium （3 genera and 5 species）. There were obvious seasonal variations in the species composition and predominant species. The cells and species of Bacillariophyta were predominant in the first 3 times investigation, but Ceratium became predominant in the last investigation. The mean value of chlorophyll a concentration was 6.81 and 6.10 mg/m^3, ranging from 0.98 to 10.60 mg/m^3 in the area of artificial reef and the control, respectively. The mean value of biomass was 252.95 mg/m^3 and 123.69 mg/m^3 ,and the biomass ranging from 41.06 to 706.63 mg/m^3 in the area of artificial reef and the control. The mean value of primary productivity were 455.23 mg C/（m^2· d） and 276.92 mg C/（ m^2 · d） ,primary productivity ranging from 27.02 to 1 222.78 mg C/（ m^2 · d） in the area of artificial reef and the control. The peak quantity of phytoplankton in the reef district and the control area were 269.6 ×10^4 cell/m^3 and 187.4 ×10^4 cell/m^3 and the lowest were 220.9 ×10^4 cell/m^3 and 114.7 ×10^4 cell/m^3, respectively. The biomass and quantity of phytoplankton in the reef district were higher than that in control area during the investigations, varying with season. In the same season, the biomass, and nutritiens materials in the artificial reef area were higher than those in the control area.
