摘　　要：为了研究“乌-昌-石”区域燃煤对空气质量的影响,运用CALPUFF模型对区域消耗燃煤的工业企业源的不同污染因子的扩散进行模拟分析,得到SO2、NOx、PM2.5、PM10的时空分布情况。结果表明:SO2、NOx、PM2.5、PM10四种污染因子的扩散均有着明显的季节性差异,采暖季(1月)污染物的扩散面积较大,且浓度较高,非采暖季(6月)污染物的扩散面积较小;从地区分布情况来看,浓度较高的区域分布在昌吉洲的阜康市和乌鲁木齐市的米东区、新市区等地,石河子、五家渠和沙湾县的浓度相对较低。污染物对区域浓度的贡献不仅与污染物排放量相关,气象条件和地形条件也是重要的影响因素。In order to study the effect of coal on air quality in the“Wu-Chang-Shi”area,the CALPUFF model was used to simulate the emission and diffusion of different pollution factors emitted from different coal-combustion industrial enterprises in the“Wu-Chang-Shi”area and to obtain the spatial-temporal distribution characteristics of SO2,NOx,PM2.5 and PM 10.Result indicated that there is a significant seasonal difference in the spread of four pollutions.In the heating season(January),the diffusion area of pollutants is larger,and the concentration value is higher.The non-heating season(June)has a small diffusion area of pollutants.From the perspective of regional distribution,the areas of higher concentration are contributed with Fukang City,Midong District and the New Urban Area.The concentration values of Shihezi,Wujiaqu and Shawan are relatively low.The contribution of pollutants to regional concentrations is not only related to pollutant emissions,but also meteorological and topographical conditions.
