摘要：

In this study, a coupled MM5-CAMx air quality modeling system is proposed for simulating the PM10 (which stands for the suspended particulate matter less than 10 mu m in diameter) concentration in Beijing, China. The PSAT (particulate matter source apportionment technology) technique is used to investigate the PM10 source apportionment in this area. The results indicate that the influence from regions outside of Beijing including Hebei province, Shanxi province, Tianjin city, and Inner Mongolia cannot be ignored, and the total emission source contribution ratio (ESCR) from these regions is 26.65%. Emissions from four local industries in Beijing including stationary emission source, road dust emission source, construction sites dust emission source, and fugitive industrial emission source, which has an ESCR of 59.59%, are main local contributors of PM10. Further analysis shows that these four industry emissions located in the urban area of Beijing are main contribution sources of PM10 pollution in Beijing, with an ESCR of 51.67%. The results obtained can provide useful information for Beijing's PM10-emission control and abatement. They can also be used for further pollution-mitigation plans establishment and providing a solid support for sound air quality management.
