主　　题：甲烷产生 warming soil 

摘      要：Peatlands, though covering only 3% of the earth surface, contain 300–400 pg carbon (C) and account for ∼30% of the global soil C pool [1], [2]. Global warming would influence the CH4 release from peatlands through accelerating the fermentation of large quantities of long-accumulated soil organic carbon to CH4 by microorganisms particularly methanogens [3]. However, the ultimate CH4 budget in peatlands under the global warming scenario is also determined by changes in the CH4 oxidation activity of the methanotrophs [4]. Thus, identifications of active methanogens and methanotrophs, as well as their metabolic potentials in peatlands, are essential for understanding the overall peatland feedback to global warming.
