Abstract: Carbon fluxes from a non-cropping paddy field in the Lower Reaches of Liaohe Plain were measured by a closed-chamber and gas chromatography-based system. The result showed that carbon fluxes were changed as temperature changed. The emission of CO2 and N2O from soil was significant during thawing. The soil of paddy field was the source of atmospheric CO2 and N2O during non-cropping season, and the soil as a sink or source of atmospheric CH4 was not significant.
