泥炭地微生物群落及其对碳封存和气候调节的影响。它是由泥炭地科学家、微生物生态学家、土地管理者和非政府组织撰写的，他们参加了2019-2020年在英国曼彻斯特大学举行的一系列三个研讨会。我们的综述表明，当地下水位恢复时，有时观察到的甲烷通量的增加是基于植被中不稳定碳的可用性和缺乏替代终端电子受体。泥炭地微生物群落对气候变化引起的植被变化以及随后地下碳基质输入的数量和质量的变化反应较快。影响泥炭地微生物群落和碳循环的气候变化的其他后果包括雪盖的变化和永久冻土的融化。面对快速的气候变化，恢复有弹性的微生物群对于维持泥炭地系统的气候调节功能至关重要。能够更快地确定微生物群落和功能特征的技术发展支持朝着这一目标取得进展，这将需要强有力的跨学科方法。

peatland microbial communities and the implications for C sequestration and climate regulation. It is authored by peatland scientists, microbial ecologists, land managers and non-governmental organisations who were attendees at a series of three workshops held at The University of Manchester (UK) in 2019–2020. Our review suggests that the increase in methane flux sometimes observed when water tables are restored is predicated on the availability of labile carbon from vegetation and the absence of alternative terminal electron acceptors. Peatland microbial communities respond relatively rapidly to shifts in vegetation induced by climate change and subsequent changes in the quantity and quality of below-ground C substrate inputs. Other consequences of climate change that affect peatland microbial communities and C cycling include alterations in snow cover and permafrost thaw. In the face of rapid climate change, restoration of a resilient microbiome is essential to sustaining the climate regulation functions of peatland systems. Technological developments enabling faster characterisation of microbial communities and functions support progress towards this goal, which will require a strongly interdisciplinary approach.
