The Influence of Grazing Intensity on Exchanging Fluxes of Nitrous Oxide, Methane and Carbon Dioxide from Grassland

Abstract:

Grassland ecosystem is the main part of terrestrial ecosystem. The variations of greenhouse gas (N₂O, CH₄ and CO₂) exchanging fluxes from grassland can influence global greenhouse gases payments balance. And the main land use pattern of grassland is grazing. The grazing impacts on the exchanging fluxes of N₂O, CH₄ and CO₂ from soil of grassland by influencing soil physical properties (such as soil moisture, temperature and porosity) of grassland. This paper analyzed the results of previous studies by the way of comparison, and we summarised that the grazing reduced CH₄ uptake and N₂O emissions of grassland, but which does not change the sources and sinks pattern of atmospheric greenhouse gases. However, the grazing significantly increased the emissions of CO₂ from grassland.
