摘　　要：对几种常用的大气污染物扩散模式和焦作城区大气SO2污染状况进行了分析,建立了适合于焦作市城区大气SO2污染的解析模型,在模型中尝试性地将面源污染产生的质量浓度贡献转化到背景值中计算,简化了解析模型;利用该模式计算1996～2000年焦作市城区大气中的SO2质量浓度并与监测数据进行对比分析,结果表明该模型适合研究区的实际情况.Several often_used diffusing models of air pollution are analyzed. On the basis of the analysis of the pollution feature,the diffusing model of SO_2 pollution applied to the air of the urban area of Jiaozuo City is set up. In the model,the contribution from area pollution sources are calculated by the background concentration,so the model was greatly simplified. The SO_2 concentration from 1996 to 2000 is also calculated by this model. Compared with the monitored concentrations,it is found that the model can be used to predict the atmospheric environmental concentration better.
