摘要
为分析2013年1月北京市严重雾霾原因,在总结前人相关研究成果和气象数据的基础上,得出雾霾天气形成的原因、春夏秋冬4个季节PM_（2.5）的组分变化规律、本地贡献率、PM_（2.5）与气象参数相关度。通过对细颗粒物的来源解析,得出燃煤产生的细颗粒物占15%~19%。在此基础上重点分析了燃煤产生的污染物对大气所造成的污染特点,系统地对近年来国内外燃煤产生PM_（2.5）机理的研究现状,抑制PM_（2.5）/PM10产生的措施,以及目前国内大气污染治理存在的问题进行了总结和归纳。拟为北京市雾霾的治理提出合理建议。
In order to analyze the causes of severe haze weather in January 2013 in Beijing,on the basis of summarizing the relevant research results and meteorological data,it is concluded that the causes of the formation of haze weather,the change rules of PM_（2.5）components in four seasons,local contribution,the correlation of PM_（2.5）and meteorological parameters. By means of the previous source apportionment of fine particulate matter,fine particulate matter produced by burning coal accounts for 15% ~ 19%. The characteristics of atmospheric pollution were analyzed on the basis of the pollutants from coal combustion. Research status of the mechanism of fine particulate formation during coal combustion and the measures of restraining PM_（2.5）/ PM10 formation at home and abroad,and China＇ s domestic problems of air pollution were summarized.Eventually,rational suggestions for the control of severe smog events were put forward.
