ABSTRACT:
Seagrass ecosystem is a potential
bank for carbon sink. In the paper, we compared the distribution of bacterioplankton,
picoeukaryotes and Synechococcus in seagrass ecosystem in Xincun Bay and coral ecosystem
in Sanya Bay and found that quantity of bacterioplankton was higher in seagrass
ecosystem, and picoeukaryotes had similar distribution pattern with that of bacterioplankton.
However, quantity of Synechococcus distribution was higher in coral ecosystem and
higher in Sanya Bay. Comparing the unit of quantity of bacterioplankton, picoeukaryotes
and Synechococcus in Xincun Bay with that of Sanya Bay, open sea of the South China
Sea and Indian Ocean, results showed that the highest quantity of bacterioplankton
was in Xincun Bay, and the lowest was in open sea of the South China Sea. The quantity
of picoeukaryotes had the similar pattern with that of bacterioplankton. Pattern
of Synechococcus quantity was different, which was the highest in Sanya Bay. These
results indicated that seagrass ecosystem was more suitable for bacterioplankton
and picoeukaryotes growth.
