冻土微生物在冻土生物地球化学循环中起着重要的作用,并且在一定程度上可以指示全球气候变化.在全球气候变暖的背景下,研究冻土微生物群落特征及其与环境因子变化的关系是当前热点研究领域.系统综述了冻土微生物群落的复杂性以及其影响因素、冻土微生物生态功能及其对碳氮循环的反馈机制、冻土微生物对环境气候变化的响应机理,旨在为研究冻土微生物对全球气候变化的响应及其在生态系统中的作用提供参考.
The permafrost microorganisms plays an important role in the biogeochemical cycle of the permafrost and can indicate the global climate change to a certain extent.Under the background of global warming, the characteristics of the microbial communities in the frozen soil and their relationship with environmental factors And the relationship between them is a hot research field.The complexity of the microbial community in permafrost and its influencing factors, the ecological function of permafrost and its feedback mechanism on carbon and nitrogen cycle, the response mechanism of permafrost microorganisms to environmental and climate changes are systematically reviewed It provides a reference for studying the response of permafrost microorganisms to global climate change and its role in the ecosystem.
