Peatland represent a globally significant stock of carbon and sources of greenhouse gases (GHG) including methane (CH4). Ongoing disturbance of peatlands alters ecosystem function and could lead to loss of soil carbon stocks and altered rates of GHG fluxes resulting in significant climate impacts. The proposed research program will investigate the interaction of peatlands and climate focusing on: 1) the impact of climate change on peatland ecosystem function, 2) GHG exchange from managed peatlands, and 3) the role of free-phase gas (bubbles) on managed peatland CH4 emission. Results from this research program will improve peatland management in a changing climate. Quantification of managed peatland GHG fluxes is needed for national inventory reports and can be used for development of mitigation strategies.

泥炭地代表了全球重要的碳储存和包括甲烷（CH4）在内的温室气体（GHG）来源。泥炭地的持续扰动改变了生态系统的功能，可能导致土壤碳储量的损失和温室气体通量的变化，从而造成重大的气候影响。拟议的研究计划将调查泥炭地和气候的相互作用，重点是：1）气候变化对泥炭地生态系统功能的影响，2）管理泥炭地的温室气体交换，以及3）自由相气体（气泡）对管理泥炭地CH4排放的作用。这项研究计划的结果将改善气候变化中的泥炭地管理。国家清单报告需要量化管理下的泥炭地温室气体通量，可用于制定缓解战略。
