摘　　要：在全球气候环境演变的背景下,认识海洋微型生物对碳循环的贡献,需要了解其过程和机制。最近提出的"微型生物碳泵"理论阐释了海洋储碳的一个新机制:微型生物活动把溶解有机碳从活性向惰性转化,从而构成了海洋储碳。这个过程当中,自养与异养细菌、病毒、原生动物等具有不同生理特性微型生物类群扮演着不同的生态角色,本文将围绕微型生物碳泵主线分别论述之。The oceans are full of microorganisms, which play a significant role in global carbon cycle. Microbial carbon sequestration in the ocean, as a cutting-edge scientific issue, receives a great deal attention in the context of global climate change. Based on the microbial carbon pump conceptual framework, microbes are major producers of recalcitrant dissolved organic carbon （RDOC） that can stay in ocean water column for long time storage. Different microbial groups contribute to RDOC carbon pool in different ways. This paper addresses groups such as autotro- phic and heterotrophic microorganisms, viruses and protozoa with respect to their various eco- logical characteristics and specific roles in RDOC formation.
