| 摘 要： | 基于AERMOD大气扩散模型，利用许昌市2009年的气象资料、地形资料分析了污染源主导风向上SO2年均落地距离与落地浓度的关系及不同排气筒高度与污染源主导风向上SO2年均最大落地浓度和最大落地距离的关系。结果表明，在特定的气象条件和污染物排放量条件下，主导风向下风向的SO2落地浓度约是上风向的4．8倍；污染源排气筒高度越高，SO2年均最大落地浓度愈小，最大落地浓度点与污染源的距离越远，因此提高污染源排气筒高度能够在一定程度上降低SO2年均落地浓度，减小污染源对地面影响。

| Abstract: | The relationship of SO2 annual ground level distance with ground level concentration and the relationship of different chimney heights with SO2 annual ground maximum concentration and ground maximum distance in pollution leading wind are analyzed using meteorological data and terrain data of Xuchang City on the basis of AERMOD atmospheric dispersion model.In certain meteorological condition and emissions of pollutants,the finding indicate that SO2 annual ground level concentration in the down wind is 4.8 ti... |
