| 摘 要： | 运用三维欧拉传输、转换、迁移模式对重庆城区各种大气污染源对大气ＳＯ２浓度的贡献数值进行模拟，分析重庆城区ＳＯ２污染形成的原因。结果表明，民用源和低矮工业源对地面ＳＯ２污染浓度贡献最大，而中高架源则主要影响高层大气，是高空大气污染及酸雨形成的重要原因。

| Abstract: | A three dimensional Eulerian transportation,conversion and transition model was used to calculate the SO 2 concentration contribusted by each type of emission sources in the urban of Chongqing to diagnose the formation of SO 2 pollution in atmosphere.It was shown that the pollution on ground level was dominated by low level sources,whereas the upper air pollution and acid rain was mainly due to the middle and high level source. |
