摘要:

季风驱动下的南海海洋动力过程有着季节性的多尺度变化特征, 显著影响南海海洋生态系统的演化进程。海洋细菌作为海洋生态系统中物质循环和能量流动的重要组成部分, 对环境变化和海洋多尺度动力过程有着积极的响应。将微生物生态过程与海洋动力过程相结合, 研究微生物的群落结构、动态变化及其与海洋环境过程的耦合, 是目前国际海洋科学多学科交叉研究的热点之一。文章以国家自然科学基金重点项目“季风环流影响下的南海海洋细菌多样性特征及其生物海洋学意义”的主要研究成果为基础, 从南海北部上升流、海洋锋面、中尺度涡旋、次中尺度过程及其对海洋细菌多样性和生态系统可能的影响等几个方面, 探讨当前的研究进展和初步研究成果。

Abstract:

Ocean dynamic processes in the South China Sea driven by the monsoon are characterized by seasonal and multi-scale variations, which have significant impacts on the evolution of marine ecosystems. Marine bacteria, as an important component of material cycle and energy flow in marine ecosystems, have active responses to the environmental changes associated with multi-scale dynamic processes. The interdisciplinary research on microbial community structures, their dynamic variation and associated physical processes is one of the hot issues in marine sciences, which combines marine microbiology, microbial ecology and physical oceanography. Based on the primary results of the Key Research Program, "Study on bacteria diversity coupled with the monsoon circulation in the South China Sea and significance in microbial oceanography" supported by the National Natural Science Foundation of China, we discuss in this paper current research progress, including coastal upwelling, seasonal thermal fronts, mesoscale eddy, sub-mesoscale processes, and their potential impacts on the marine bacterial diversity and local ecosystem in the South China Sea.

Key words: South China Sea, ocean dynamics, bacteria diversity, microbial oceanography
