摘　　要：应用富集因子分析法对贵阳市7种PM2.5主要排放源(土壤风沙尘、城市扬尘、道路尘、建筑水泥尘、钢铁尘、燃煤尘、机动车尾气尘)中的污染元素进行了分析。分析结果表明,贵阳市各PM2.5排放源中的污染元素均存在着不同程度的富集污染现象,这些元素的富集污染程度易受人类活动的影响,并经过长时间的积累在城区内富集,使得城区内PM2.5的污染现象突出。The pollution elements of the seven major emission sources in Guiyang City have been analyzed by en- richment factor. These sources covered soil dust, fugitive dust, road dust, cement dust, steel and iron dust, coal dust, and vehicle exhaust dust. It showed that the pollution elements in these emission sources were enriched to a certain extent, and it was susceptible to the human activity. The accumulation of these pollutants in a long duration has caused a serious PM2.5 pollution in the urban center. The research provided a scientific basis for the air pollution control and would be helpful for improving the environmental air quality.
