摘要:

利用流式细胞仪对渤海浮游病毒的丰度分布进行了研究。结果表明, 浮游病毒丰度在6.40 ×105—3.59 × 107个/mL之间。辽东湾断面, 浮游病毒丰度春季在西部海域较高, 夏季在中部海域较高, 秋、冬季在东、西部海域均较高; 渤海湾断面, 4 季丰度均在中部海域出现高值区; 莱州湾断面, 夏、秋、冬季均在东部海域出现丰度高值区; 渤海海峡断面, 春、秋、冬季于海峡中部海域丰度较高。垂直分布上, 表层和底层水体浮游病毒丰度在夏季差异性显著, 在其它季节无显著差异。夏季浮游病毒丰度显著高于其它季节。夏季, 连续站浮游病毒丰度昼夜波动幅度较大, 冬季较平缓。相关性分析表明, 浮游病毒丰度在春、夏、秋季均与温度显著正相关; 夏季与异养细菌丰度、微微型真核浮游植物丰度显著正相关; 秋季与微微型浮游植物丰度显著正相关; 冬季仅与异养细菌丰度显著正相关。

Abstract:

We investigated the abundance of virioplankton in 2010—2011 in the Bohai Sea by flow cytometry. Virioplankton abundance ranged from 6.40×105 to 3.59×107/mL. Shown in the northern transect (Liaodong Bay), the abundance was higher in spring, autumn and winter in the eastern and western sectors, and high in the central in all seasons. In the western transect (Laizhou Bay), viral abundance was high in summer, autumn and winter. In the eastern transect (Bohai Strait), it was high in spring, autumn and winter. In vertical direction, significant difference between the virioplankton abundance of the surface and that of the bottom of the sea in summer was found. Diel fluctuation in the abundance was quite obvious in the anchor stations in summer, but in winter. Virioplankton abundance was found closely related with heterotrophic bacteria, picophytoplankton, and temperature: positively between viral and bacterial abundance in summer and winter, and between virioplankton and picophytoplankton in summer and autumn.
