【摘要】 海洋细菌在海洋生态系统中的重要作用随着微食物环的提出被深入认识和充分肯定。本文概述了海洋细菌在微食物环中的重要生态作用及微食物环的研究进展,海洋细菌在碳的生物地球化学循环中的重要性,海洋细菌的活性及其群落结构与功能,分析了藻际环境特性和藻际微生物在赤潮多发海域的生态作用,提出了我国海洋细菌生态学研究的若干新思考与新任务,强调了基于"以菌治藻"的新理念,开展针对于赤潮灾害防除的"微食物环-赤潮-关键微生物菌群"耦合互作这一重要科学问题研究的必要性及紧迫性。更多还原

【Abstract】 The role of marine bacteria playing in the marine ecosystem and the biogeochemical cycles of carbon, and the advances in microbial loop research were reviewed in this paper. The community structure and function and especially the bacterial activity in marine environment and the ecological function of phycosphere bacteria in the frequent occurrence area of Harmful algal blooms (HABs) were discussed as well. The importance and urgency to carry out the study on the coupling effect of "microbial loop-HABs-key microbial groups" were suggested based on the need of frontier research topics.更多还原
