The generation process and temporal evolution of negative oxygen ions in a atmospheric plasma are numerically simulated in this paper. The results show that there exists a knee point in the attenuation process of negative oxygen ions, followed by a long time stationary phase. The density of negative oxygen ions in the stationary phase has a linear relation with the initial electron number density. Moisture content has a large effect on the temporal evolution of negative oxygen ions.
