A deeper understanding of the effects of experimental warming and elevated ozone (O 3 ) concentration on carbon dioxide (CO 2 ) fluxes is imperative for reducing potential CO 2 emissions in agroecosystems, but are less understood particularly in rotational wheat ( Triticum aestivum )-soybean ( Glycine max ) croplands. In order to understand such effects on CO 2 fluxes from winter wheat-soybean rotation, a field experiment was conducted by using the open-top chamber (OTCs) during the growing seasons of 2012 and 2013 at an agro-ecological station in southeast China. The experimental treatments included the control (CK), experimental warming (T, crop canopy temperature increased by ~2 °C), elevated O 3 concentration (O, O 3 concentration about 100 ppb) along with temperature enhancement (OT, elevated ~2 °C temperature plus 100 ppb O 3 ). The results showed that warming significantly increased the mean CO 2 fluxes ( MCF ) and the cumulative amount of CO 2 ( CAC ) from soil and soil-crop systems, while elevated O 3 and warming enhancement (OT) significantly reduced MCF and CAC . Besides, warming significantly reduced the biomass of winter-wheat, but it insignificantly decreased the biomass of soybean in the harvest period. The O and OT treatments significantly reduced the biomass of winter-wheat and soybean cropping systems in the harvest time. Both warming and elevated O 3 concentration decreased the temperature sensitivity coefficients ( Q 10 ) in soil respiration during the experimental period. Overall, our results indicate that elevated O 3 concentration compensates the effect of warming on CO 2 emission to some extents, which has a positive feedback impact on the climate system
