| 摘 要： | 采用CALPUFF空气质量模型,对2006年太原市城区大气污染源排放SO2的传输及转化过程进行数值模拟.借助于地理信息系统软件和其它工具软件,结合实际监测结果详细分析了太原市城区范围内的SO2浓度分布特点及其对各关心点的浓度贡献.结果表明:太原市1、4两月大气污染物整体向东南方向扩散,7月由市中心向四周均匀扩散,10月向东北方向扩散;太原市7月份最不利于污染物扩散,其次为1月份;相比之下,4、10两月污染物扩散能力强.从空间分布来说,太原市SO2污染总体呈现东部重于西部,北部重于南部的态势;高值区主要分布在北部太钢工业区、西部煤化工工业区和东部工商混合区.太原市污染源排放对各关心点的SO2浓度贡献值呈现1、7月高,4、10月低的趋势,贡献值较大的关心点由高到低依次为涧河、坞城、桃园、尖草坪.

| Abstract: | CALPUFF air quality model was used to simulated the transmission and the transformation of the SO2 by sources in 2006 Taiyuan.A series of analysis about the SO2 concentration spatial distribution characteristics and the contribution to each concerned point were analyzed by using the GIS and other softwares.The results showed that:The urban in January and April,Taiyuan the atmospheric pollutants spread to southeast,in July from the center to the surrounding uniform proliferation,the proliferation of October ... |
