冻土退化可能导致土壤碳(C)损失，这对全球碳循环至关重要，并由微生物介导。我们在原地证明，永久冻土退化改变了多样性，并可能降低活性层微生物群落的稳定性。这些变化与土壤碳流失和潜在的正碳反馈有关。这项研究提供了微生物介导的机制，负责退化的永久冻土活动层内的碳损失，有助于模拟未来情景下的碳排放。
Permafrost degradation may induce soil carbon (C) loss, critical for global C cycling, and be mediated by microbes. Despite larger C stored within the active layer of permafrost regions, which are more affected by warming, and the critical roles of Qinghai-Tibet Plateau in C cycling, most previous studies focused on the permafrost layer and in high-latitude areas. We demonstrate in situ that permafrost degradation alters the diversity and potentially decreases the stability of active layer microbial communities. These changes are associated with soil C loss and potentially a positive C feedback. This study provides insights into microbial-mediated mechanisms responsible for C loss within the active layer in degraded permafrost, aiding in the modeling of C emission under future scenarios.
