文摘

CO2 exchange patterns were evaluated using a closed-chamber technique. Precipitation is the dominant factor that controls carbon fluxes. Grazing intensity regulates changes that could mediate carbon sequestration. Interaction of year and grazing intensity only affected NEE, not GEP or Re. Moderate grazing site was greater C sinks for the three growing season.
