湖泊沉积物中微生物与生物地球化学循环
|
摘要
随着全球气候不断上升,湖泊富营养化状态不断加剧,湖泊沉积物中各种元素的循环过程逐渐受到关注。微生物作为生物地球化学循环的主要执行者,影响着全球气候变化和湖泊生态环境。围绕碳、氮、硫要素,综述了湖泊沉积物中微生物介导的生物地球化学循环过程,包括甲烷代谢、脱氮、产氨、硫酸盐还原等过程。最后总结了当前研究中存在及需要解决的一些问题,并展望湖泊沉积物中微生物参与下的生物地球化学循环的研究方向。
As the global climate continues to rise, the eutrophication status of lakes continues to increase, and the cyclical processes of various elements in lake sediments are receiving increasing attention. Microorganisms, as the main executor of the biogeochemical cycle, affect global climate change and lake ecological environment. This paper focuses on the elements of carbon, nitrogen, sulfur, and summarizes the biogeochemical cycle processes with microbial in lake sediments, including processes such as methane metabolism, nitrogen removal, ammonia production, sulfate reduction. Finally, some problems existed and needed to be solved in the current study are summarized, and the research direction of the biogeochemical cycle under the participation of microorganisms in lake sediments will be prospected.
