摘　　要：利用CALPUFF耦合MM5的大气扩散模型,对四川省凉山彝族自治州2007年工业排放PM10的扩散传输进行数值模拟,分析了污染物的浓度时空分布以及影响污染物浓度分布的主要因素。结果表明:CALPUFF耦合MM5模型对凉山州2007年工业排放PM10的浓度模拟有着较好的适用性;污染物主要沿着安宁河和黑水河分布,浓度分布特征随时间变化,其中冬季污染较为严重;各市(县)的PM10浓度值有空间差异,西昌和甘洛污染最为严重,季平均浓度分别为67.81μg/m3和57.23μg/m3;凉山州PM10的浓度分布受气象条件、地形和污染源的地理位置的综合影响。In this paper,the diffuse transport of industrial emission PM10 in Liangshan YI Autonomous Prefecture in 2007 was simulated by CALPUFF coupled with the MM5 model.The space-time distribution of pollutant concentration and its main influencing factors were analyzed.Results show that CALPUFF coupled with the MM5 model is applicable to simulate the concentration of industrial emission PM10 in Liangshan.The pollutant is diffused mainly along the Anning River and Heishui River,and the distributive characteristics of concentration change along with variation of time,pollution is more serious in winter.The concentration is higher in Xichang and Ganluo,their season-average-concentration is 67.81μg/m3 and 57.23μg/m3,respectively.Affected by the weather conditions,terrain and geographical distribution of sources,spatial differentiation of PM10 concentration exists among study areas.
