Abstract	Using the static chamber method, CO flux across the water-air interface of Nihe reservoir was measured for 24 hours over a one-year cycle in China. Gas ebullition and gas emission in winter was not considered in this study. According to our results, Nihe reservoir was a total carbon source (690.42 ± 15.18 mg $m^{−2}$ $d^{−1})$ during the year. The maximum and minimum CO flux were 50.52 (mg $m^{−2}$ $h^{−1})$ and 17.87 (mg $m^{−2}$ $h^{−1}),$ respectively. The diurnal and seasonal variation of CO flux was obvious: the CO emission during the daytime was lower than night; the CO flux was highest in summer (31.52±2.27 mg $m^{−2}$ $h^{−1}),$ and lowest in fall (25.03 ± 3.21 mg $m^{−2}$ $h^{−1}).$ CO emission was negatively correlated with temperature, wind speed, and chlorophyll, while positively correlated with alkalinity. Ultimately, no single environmental factor can solely responsible for CO flux.
