摘要	该文对中国黄海和东海的蓝细菌在春、秋两季的生态分布特点进行了研究和比较,对黄海蓝细胞从10月至次年6月的生态分布进行了研究.1.东黄海海区：在秋季（2000年10月19日至11月29日）和春季（2001年3月26日至4月24日）两个季节中蓝细菌丰度在0.19～7.84×10<'4>cell/ml之间,生物量在0.56～13.74μgC/L之间,整体水平上春季比秋季高（蓝细菌的丰充与生物量平均值春季分析为4.83×10<'4>cell/ml和7.25μgC/L;秋季分别为1.72×10<'4>cell/ml和5.07μgC/L）,东海比黄海高（蓝细菌生物量平均值春季黄海和东海分别为4.42μgC/L和5.52μgC/L;秋季黄海和东海分别为7.02μgC/L和7.45μgC/L）.2.黄海海区：黄海蓝细菌丰度与生物量随时间变化趋势为10月至12月降低（蓝细菌丰度分别为15×10<'4>cell/ml和1.19×10<'4>cell/ml,生物量分别为4.41μgC/L和3.49×10<'4>cell/ml）,4月（蓝细菌丰度与生物量分别为4.68×10<'4>cell/ml和7.02μgC/L）与12月相比有明显增高,蓝细菌丰度4月是12月的3.93倍,生物量4月是12月的2.01倍,4月至6月蓝细菌生物量大致稳定,略有增加（5月和6月蓝细菌丰度分别为5.23×10<'4>cell/ml和5.25×10<'4>cell/ml,生物量分别为7.85μgC/L和7.88μgC/L）.研究发现蓝细菌在水体中的垂直分布与温度变化比较一致.
其他摘要	1. The abundance, biomass and character of distribution of Synechococcus in the East China Sea and the Yellow Sea were investigated as well as the contribution of Synechococcus to the total planktonic biomass in two seasons, autumn (Oct-Nov, 2000) and spring (Mar-Apr, 2001). In autumn, the abundance and biomass of Synechococcus were 1.72 * 104cell/ml and 5.07μgC/L respectively and in spring these two value were 4.83 * 104cell/ml and 7.25μgC/L respectively. Both of the abundance and the biomass of Synechococcus were higher in spring than in autumn and higher in the East China Sea than in the Yellow Sea. The contributions of Synechococcus to the total planktonic biomass in the two seasons were familiar with 43.9% in Autumn and 43.4% in Spring. Both of the biomass of Synechococcus and the contribution of Syenchococcus to the total planktonic biomass presented a clear vertical distribution tendency, surface>middle>bottom, except the contribution of Syenchococcus to the total planktonic biomass in autumn which had the maximum in the bottom. The abundance, biomass and character of distribution of Synechococcus in the Yellow Sea were investigated as well as the contribution of Synechococcus to the total planktonic biomass from Oct. 2000 to Jun. 2001. The abundance and biomass of Synechococcus reached their minimums (1.19 * 104 eel I/ml and 3.49μgC/L, respectively) from Oct. 2000 to Dec. 2000. From Dec. 2000 to Apr. 2001, the abundance and biomass of Synechoccus increased sharply to 4.68 * 104cell/ml and 7.02ngC/L respectively, and then kept some kind of stable with a little increasing from Apr. to Jun. 2001. In our research, the maximums of the abundance and biomass of Synechococcus (5.25 * 104cell/ml and 7.88ugC/L, respectively) appeared in Jun. 2001. The vertical distribution of the Syenchococcus was well agreed with the temperature. In Apr. 2001, when the temperature was uniform in the water column, the vertical distribution of Syenchococcus appeared a clear tendency of decreasing from surface to the bottom which was correlated with the light. The contribution of Synechococcus to the total planktonic biomass changed from 32.26 to 42.5% in the different voyages. In the same region (near shore) of the sea area investigated, it presented a similar pattern of change with the abundance and biomass of Synechococcus and the maximum and minimum were 27.97% (Oct. 2000) and 38.82% (Jun. 2001) respectively. Also, its vertical distribution had a same pattern as those of the biomass and abundance of Synechococcus, decreasing from surface to bottom.
