Ecosystem and Climate

泥炭地是全球重要的碳储量和温室气体（GHG）来源，包括甲烷（CH4）。泥炭地的持续扰动会改变生态系统功能，并可能导致土壤碳储量的损失和温室气体通量的改变，从而产生重大的气候影响。拟开展的研究项目将重点研究气候与泥炭地的相互作用：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；3)自由相气体（气泡）对管理泥炭地CH4排放的作用。这一研究项目的成果将改善气候变化下泥炭地的管理。国家清单报告需要对管理的泥炭地温室气体通量进行量化，并可用于制定缓解战略。

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.
