摘　　要：预估模式SCREEN3是大气环境影响评价的基础预测模式,通过选择估算模式中2种不同的地表类型选项,针对同一组污染源数据进行浓度计算,分析了地表类型对预测结果影响情况。结果表明:对于不同类型的源强,地表类型对预测结果的影响程度各异,在大气环境影响预测中正确地选择地表类型非常必要。The prediction model SCREEN3 is a basis of atmospheric environmental impact assessment model. In this paper, two different surface types option are chosen to calculate concentration results base on the same set of pollution source data, then the influence of surface type on the prediction are analyzed. The results show for different types of source, impact from different surface types are various. It is necessary to choose the type of surface correctly in the atmospheric environmental impact prediction.
