根据2005年4－5月（春季）、8月（夏季）和11月（秋季）对大亚湾大鹏澳海区表层的现场调查结合营养盐加富实验，探讨了不同季节氮（NO3－或脲氮 (urea)）和无机磷（PO43－）营养元素对浮游植物种类组成的潜在影响。大鹏澳海区浮游植物优势种有明显季节变化，秋季种类组成的平面变化最明显。春季浮游植物平均细胞密度最高但多样性指数最低。实验结果显示，春季至夏季浮游植物优势种翼根管藻模式变型Rhizosolenia alata f. genuina、丹麦细柱藻Leptocylindrus danicus和绕孢角毛藻Chaetoceros cinctus之间的演替可能受氮、磷条件变化的控制。夏季优势种菱形海线藻Thalassionema nitzschioides和威氏海链藻Thalassiosira weissflogii之间的演替可能受营养条件外的因素控制。尽管磷被认为是该海区浮游植物生长的主要限制因子，但夏季无机氮磷比值较高的实验组中未出现磷限制现象，无机氮磷比值的变化对浮游植物种类组成也没有显著影响，而秋季氮对浮游植物种类组成有较明显的潜在影响。

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.
