摘　　要：大气细颗粒物PM_(2.5)污染危害大、成因复杂,因此,对其进行控制与治理具有重要意义。本文通过对PM_(2.5)的定义、主要组成、危害和影响以及PM_(2.5)的溯源进行分析,并进行了相关研究总结。其中,在对PM_(2.5)的溯源分析中,解析了各类重要污染源对PM_(2.5)的形成的贡献及比重。同时,通过分析PM_(2.5)的来源及贡献率,明确了主次顺序,再结合具体的分析情况,从源头管控、过程管控两个方面提出了合理控制PM_(2.5)的对策,从而为空气环境治理提供参考。Fine particulate matter PM_(2.5) pollution has great harm and complex causes,therefore it is meaningful to control and govern it.In this paper,the defi nition,main composition,harm and impact of atmospheric fi ne particulate matter PM_(2.5),as well as the traceability analysis of PM_(2.5),relevant research is summarized.Among them,in the traceability analysis of PM_(2.5),the contribution and proportion of all kinds of important pollution sources in the formation of PM_(2.5) are analyzed.At the same time,through the analysis of PM_(2.5) source and contribution rate,the order of primary and secondary is defi ned,and then combined with the specifi c analysis,reasonable PM_(2.5) control countermeasures are given from the source control and process control,so as to provide reference for air environment control.
