自2008年2月至2008年11月在深圳湾布设了10个站位,对该海域进行了每季一次共4个航次的浮游细菌生物量调查。结果表明,深圳湾浮游细菌生物量(C)变化范围为(0.82-36.42)×10?2μg·mL?1,总均值为9.97×10?2μg·mL?1。深圳湾浮游细菌生物量(C)季节变化不同于其他一些海湾,表现为春季(19.80×10?2μg·mL?1)>冬季(7.00×10?2μg·mL?1)>夏季(3.77×10?2μg·mL?1)>秋季(3.60×10?2μg·mL?1)的模式。在平面分布上,浮游细菌生物量(C)表现为由湾内向湾外、由近岸向离岸递减的基本格局,越靠近河口或港口,细菌生物量越高,离河口或港口越远,细菌生物量越少。浮游细菌生物量(C)与磷酸盐呈极显著的正相关(p<0.01),与总氮、总有机碳和化学耗氧量呈显著的正相关(p<0.05)，显示陆源有机物输入与浮游细菌生物量分布格局密切相关。深圳湾水体细菌数量变化范围为(0.41-18.2)×106个·mL?1,周年平均值为5.21×106个·mL?1,表明深圳湾海域富营养化严重,其富营养化程度从湾内向湾外递减。

Spatial and temporal distributions of bacterioplankton biomass were seasonally investigated at 10 sampling stations in Shenzhen Bay in February, May, August, and November of 2008. The bacterioplankton biomass ranged from 0.82×10?2 to 36.42×10?2 μg·mL?1, with an annual average of 9.97×10?2 μg·mL?1. The bacterioplankton biomass was the greatest in spring (19.80×10?2 μg·mL?1), followed by winter (7.00×10?2 μg·mL?1), summer (3.77×10?2 μg·mL?1), and autumn (3.60×10?2 μg·mL?1) in turn, revealing different seasonal patterns in this bay compared with other sea areas. The bacterioplankton biomass decreased horizontally from the inner bay to the outer bay, and from landward to seaward, with a higher biomass at some stations near river mouth and harbor. The bacterioplankton biomass was significantly positively relative to PO43?-P, TN, COD, and TOC in Shenzhen Bay. Input of organic matters from land influenced horizontal and temporal distributions of bacterioplankton biomass. The abundance of bacterioplankton ranged from 0.41×106 to 18.2×106 ind·mL?1, with an annual average of 5.21×106 ind·mL?1, implying serious eutrophication in this bay and revealing a decreasing pattern from the inner bay to the outer bay.
