摘　　要： 以广东省佛山市中心城区为研究区域,在分析城区工业污染源排放与分布特征的基础上,应用中尺度气象模式MM5耦合空气质量模式CALPUFF的方法,模拟了中心城区工业污染源排放SO2的扩散传输过程.在考虑周边污染源及本地污染物的情况下,发现ρ(SO2)模拟值与实测值的变化趋势一致,表明模拟方案可较好地反映ρ(SO2)的时空分布特征.分析中心城区工业源排放时空分布模拟结果发现,工业污染源排放与分布特征和气象环境是影响城区工业源排放SO2的时空分布的重要因素. The central district of Foshan City is considered as the study region.The distribution and emissions of industrial pollution sources are analyzed.On this basis,the diffusion and transmission of SO2 emitted by industry are simulated using mesoscale meteorological model（MM5） coupled method of air quality model CALPUFF.Considering the internal sources and the peripheral sources,the trend of the simulated mass concentration of SO2 and that of the observed mass concentration of SO2 is similar,which indicates the coupled method can simulate the variable features of SO（2） better.The simulated result of SO2 emitted by the industry in the central district shows that the distribution of industrial emissions and the meteorological environment have a significant impact on the temporal and spatial distribution of SO2 emitted by the industry in the central district.
