A series of supersaturated total dissolved gas (TDG) release tests, under different wind speeds, were carried out in laboratory and the impacts of wind speed on supersaturated TDG release process were studied. According to available release models, we estimated the release coefficients and derived a quantitative formula to describe the relationship between the release coefficient of supersaturated TDG and wind speed. Results showed that, under the condition that temperatures were among 8.5℃ and 9.5℃, the release rate was fairly slow for low wind speed, but the release rate of supersaturated TDG remarkably augmented as wind-speed increased. The release coefficient of TDG was 0.00542 h^-1 under windless condition, and others were between 0.00709 h^-1 and 0.06668 h^-1 with wind speeds ranging from 1.08 to 11.33 m／s. And, at the same time, the relative release coefficients were within the range of 1 to 12.303 in the experiment. Thereafter, a fitted quantitative formula between relative release coefficients and wind speeds was obtained, whose calculation deviation ranged from -11.76％ to 10.21％.
