Hydroclimatic shifts and anthropogenic‐driven nitrogen deposition are major outcomes of global change that could compromise the functioning of many peatlands as a carbon sink. For Sphagnum‐dominated peatlands, an emerging hypothesis is that the change could be triggered by shifts in competitive dominance among plant functional groups, specifically from the currently predominant decay‐resistant Sphagnum to the more decomposable vascular plants. However, the relationship between Sphagnum and vascular plant occurrence is notably complex and also includes facilitative interactions that are crucial to the productivity of Sphagnum, and therefore, carbon sequestration.

全球变化时代，以泥炭藓为主的泥炭地植物群落动态和固碳

水文气候变化和人为驱动的氮沉降是全球变化的主要结果，全球变化可能损害许多泥炭地作为碳汇的功能。对于以泥炭藓为主的泥炭地，一个新的假说是，这种变化可能是由植物功能群之间竞争优势的转移所触发的，特别是从目前主要的抗腐烂泥炭藓到更易分解的维管植物。但是，泥炭藓与维管植物的发生之间的关系非常复杂，并且还包括促进泥炭藓生产力和固碳的关键相互作用。
