摘　　要：对北京市控制大气污染的四期紧急措施进行量化 ,分别计算出各项控制措施实施后的排放削减量 ,建立排放清单 .采用空气质量模型 ,模拟了紧急措施实施的各阶段市区内一次大气污染物SO2 、NOx 和PM 1 0浓度的时空分布情况 ,分析和评价了四期紧急措施的环境有效性 .结果表明 ,四期紧急措施对SO2 和NOx 的控制效果较好 ,PM1The new emission inventories of Beijing city were developed based on the Four Stage Measures of Short term Air Pollution Control implemented by Beijing municipal government. The concentrations of primary air pollutants SO 2, NO x and PM10 in urban area during the time period of the Four Stages were simulated by an air quality model. It was shown that those measures have significant effects on the reductions of emissions and environmental concentrations of SO 2 and NO x , while for PM10, the control strategies were not so effective.
