| 摘要: |
| 本研究自2006年7月至2007年10月，分4个季节调查了辽东湾海域的微微型浮游生物的丰度。结果表明：夏季辽东湾的聚球藻（Synechococcus）丰度最高，平均丰度为1.89×10 4 cell/mL。秋季次之，冬季居第三位，春季最低。夏季比其他3个季节的聚球藻丰度要高一个数量级。夏季辽东湾的微微型真核藻类（Picoeukaryote）丰度最高，平均丰度为3.79×10 3cell/mL，秋季次之，冬季与春季相差不大。夏季比其他3个季节的微微型真核藻类丰度要高一个数量级。 |

| Abstract: |
| From July 2006 to October 2007,the abundance of Picophytoplankton in Liaodong Bay was investigated in four seasons.The results showed that the abundance of Synechococcus spp.in Liaodong Bay was the highest,and the average abundance was 1.89×10 4 cell/ml.Followed by autumn,the third was in winter,and the lowest was in spring.The summer was one order of magnitude higher than the other three seasons.The average abundance of eukaryotic picophytoplankton in Liaodong Bay in summer was 3.79×10 3 cell/ml,followed by autumn voyage,winter and spring voyage.Summer was one order of magnitude higher than that of the other three seasons. |
