Summary:
Peatland is a significant storage of carbon (C) and nitrogen (N) on the earth surface. Human activities in peatlands influence significantly the emissions of greenhouse gases, carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O). Methane and N2O are produced through oxidation-reduction reactions, so their emissions essentially influenced by ground water level. This paper reviews the characteristics of CH4 and N2O emissions. There were different trends of CH4 and N2O emissions from between tropical peatland and boreal and temperate peatlands. Methane emission increased significantly with the rise of ground water level above -20 cm, and larger in boreal peatland with plant mediated CH4 emission than tropical peatland with plant mediated oxygen supply.
