摘要 随着城市建设规模的扩大,北京建筑扬尘对大气颗粒物的影响越来越显著.监测数据显示:2002~2005年以来北京区域背景条件有所改善,但由于城市建设工地增多,部分市区,特别是奥运工地等周边环境的颗粒物浓度明显升高.△PM10/△SO1比值作为城市大气污染源结构的指示因子,一定程度上反应了城市建设规模及速度.统计数据显示:△PM10/△SO2比值与城市建筑面积存在明显正相关,近几年都有明显加速趋势.随着城市的扩张,北京降尘的源与汇也向外围发展,城市近郊区的通州、昌平以及房山等地由于城市建设的快速增长,降尘量成为全市增幅最大区域. With urban development, construction ash becomes more and more severe. Data analysis indicates that the concentration of PM10 at downtown, especially near Olympic construction site, became higher from 2002 to 2005. As index sign of pollution sources, the ratio of △PM10 to △SO2 reflects. construction scale and speed. Atmospheric dust - fall decreases at downtown and exurb, but increases near the suburb, i.e. Tongzhou,Changping and Fangshan District.
