In situ survey in the surface of Dapeng’ao Bay (Daya Bay), combined with nutrient enrichment bioassays were conducted in April-May (spring), August (summer) and November (autumn), 2005 in order to better understand the potential influence of nitrogen (NO3－ or urea) and phosphate（PO43－）on the species composition of phytoplankton in this area in different seasons. In spring, the abundance of phytoplankton in Dapeng’ao Bay was the highest but the diversity index was the lowest among the three seasons. The dominant species had significant seasonal variations. The horizontal variation of species composition was more significant in autumn than that in any other season. Results showed that the succession among the dominant species Rhizosolenia alata f. genuina, Leptocylindrus danicus and Chaetoceros cinctus from spring to summer may due to the change of the condition of nitrogen (N) and PO43－. In summer, there should be factors other than nitrogen or PO43－ controlling the succession between the dominant species Thalassionema nitzschioides and Thalassiosira weissflogii. Although phosphorus is consider to be the most limiting factor for the growth of phytoplankton in this area, the treatment with high N:P ratio in summer did not showed any phosphorus (P) limiting effect, and the variation of N:P ratio had little effect on the species composition. Further more, the potential impact of nitrogen on the species composition was more significant than PO43－ in autumn.
