The orientational observation of CO2 emission from paddy ecosystem in subtropical region was carried out, adopting closed static chamber technique. Under the growth condition of paddy rice, the total emission flux (Rt) of paddy CO2 had greate fluctuation in the growth course of late rice, with an average value of 926.2mg/(m2?h). The soil CO2 emission flux (Rs) had small fluctuation, with an average value of 285.4mg/(m2?h). Both fluxes appeared marked exponential relationships with air temperature and soil d...
