Using the static chamber method, CO2 flux across the water-air interface of Xiquanyan reservoir was measured for 24 hours over a one-year cycle in Harbin, China. Gas ebullition and gas emission in winter was not considered in this study. CO2 fluxes showed significant spatial-temporal differentiation. The order of CO2 flux in each test point was: A> C> D> B. The changes of water level and hydro-fluctuation zone and the distribution of aquatic plants were the main factors affecting the spatial variation of CO2 flux. In terms of time, carbon flux of daytime in Xiquanyan was significantly lower than the night. Overall, seasonal variations of CO2 flux was: spring> autumn> summer.
