| 摘 要： | 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.

| Abstract: | The microorganisms in permafrost play an important role in permafrost biogeochemical cycles,and play an indicative effect for the changes of global climate.Because of the global warming,the studies of the variations of permafrost microbial community and the relationships between the microbial communities and environmental factors have become the research focus in recent years.The advance in the studies of permafrost microbial ecology is reviewed in this paper,including the complexity of microbial community,the influence factors,the ecological functions,the feedback mechanism of carbon and nitrogen cycles,and the response mechanisms to climate change,in order to provide some useful information for the research of response of permafrost microbial to global climate change and the roles of permafrost microbial in ecosystems. |
