The biogeochemistry of peatlands: coupling carbon and nitrogen cycles

尽管在确定泥炭地的碳循环方面取得了很大进展，但目前的主要挑战是确定N在这些营养有限的系统中所起的作用。氮输入的增加，例如通过大气氮沉降，对许多陆地生态系统构成重大威胁，而碳模型受到碳和氮耦合的限制。我的工作重点是Mer blue泥炭地，这是过去十年中一系列密集测量和实验的地点。我愿回答以下问题：

Although much progress has been made in defining the C cycling in peatlands, the major challenge now is to determine the role that N plays in these nutrient-limited systems. Increases in N input, e.g. through atmospheric N deposition, pose major threats to many terrestrial ecosystems and C modelling is limited by coupling of C and N. My work focuses on the Mer Bleue peatland, the site of an intensive series of measurements & experiments over the past decade. I propose to answer the following questions:
