Field measurements were made from June 2001 to May 2002 to evaluate the e?ect of crop residue application and temperature on CO2, CH4, and N2O emissions within an entire rice-wheat rotation season. Rapeseed cake and wheat straw were incorporated into the soil at a rate of 2.25 t hm?2 when the rice crop was transplanted in June 2001. Compared with the control, the incorporation of rapeseed cake enhanced the emissions of CO2, CH4, and N2O in the rice-growing season by 12.3%, 252.3%, and 17.5%, respectively, while no further e?ect was held on the emissions of CO2 and N2O in the following wheat- growing season. The incorporation of wheat straw enhanced the emissions of CO2 and CH4 by 7.1% and 249.6%, respectively, but reduced the N2O emission by 18.8% in the rice-growing season. Signi?cant reductions of 17.8% for the CO2 and of 12.9% for the N2O emission were observed in the following wheat- growing season. A positive correlation existed between the emissions of N2O and CO2 (R2 = 0.445,n = 73,p < 0.001) from the rice-growing season when N2O was emitted. A trade-o? relationship between the emissions of CH4 and N2O was found in the rice-growing season. The CH4 emission was signi?cantly correlated with the CO2 emission for the period from rice transplantation to ?eld drainage, but not for the entire rice-growing season. In addition, air temperature was found to regulate the CO2 emissions from the non-waterlogged period over the entire rice-wheat rotation season and the N2O emissions from the non- waterlogged period of the rice-growing season, which can be quantitatively described by an exponential function. The temperature coe?cient (Q10) was then evaluated to be 2.3±0.2 for the CO2 emission and 3.9±0.4 for the N2O emission, respectively.
