Response of Methane and Nitrous Oxide Emissions from Peatlands to Permafrost Thawing in Xiaoxing’an Mountains, Northeast China

Permafrost thawing may lead to the release of carbon and nitrogen in high-latitude regions Northern Hemisphere, mainly form greenhouse gases. Our research aims reveal effects permafrost on CH4 N2O emissions from peatlands Xiaoxing’an Mountains, Northeast China. During four growing seasons (2011–2014), situ were monitored peatland under no-thawing, mild-thawing, severe-thawing conditions middle Mountains by a static-chamber method. Average site 55-fold higher than those no-thawing site. The seasonal variation emission became more aggravated with intensification thawing, which peaks larger absorption decreased zero. increased caused expansion layer subsequent increases soil temperature, water table, shifts plant communities. However, did not change thawing. but impact Mountains. Increased this region amplify global warming.
