| 摘 要： | A 2-D global chemistry-transport model is set up in this paper.The model simulates theatmospheric ozone distributions well with specified dynamical conditions.The analysis of ozonevariation mechanism shows that ozone is chemically in quasi-equilibrium except for the polar nightregion where the variation of ozone concentration is under the control of dynamical processes,thatthe oxygen atoms which produce ozone are mainly provided by the photolysis of O_2 in the upperstratosphere and by the photolysis of NO_2 in the lower stratosphere and the troposphere.and thatthe ozone is destroyed mainly by NO_x:the reactions between NO_x and O_3 and the odd oxygen cyclecontribute 80% to more than 90% of the ozone destruction.
