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 调查海区蓝细菌在浮游植物总生物量中所占百分比在32 . 26 - 42 . 5 %之间，其中近岸海区在27 . 98 - 38 . 82 %之间，其变化趋势与蓝细菌生物量的变化趋势大致相同。
In autumn , the abundance and biomass of synechococcus were 1 . 72 10 ~ 4cell / ml and 5 . 07 ( gc / l respectively and in spring these two value were 4 . 83 10 ~ 4cell / ml and 7 . 25 ( gc / 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 蓝细菌在浮游植物总生物量中所占百分比的水平分布在两个季节中不同，秋季高值区主要集中在调查海区的中部，春季高值区则主要集中在调查海区的南北两部分。
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 蓝细菌生物量和其在浮游植物总生物量中所占百分比的垂直分布在两个季节中不相同，秋季蓝细菌在浮游植物总生物量中所占百分比在表层、中层和底层中大致相当（分别为43 . 76 % 、 43 . 47 %和46 . 11 % ） ，春季蓝细菌在浮游植物总生物量中所占百分比表层最大，中层次之，底层最小（分别为65 . 55 % 、 43 . 67 %和35 . 94 % ） 。
