摘要
以天津市2010年污染源普查为主要数据源建立天津市大气污染源排放清单,采用MM5/CMAQ模式,以1、4、7、10为各季节代表性月份,模拟研究天津市各季节PM2.5来源构成变化以及"十二五"期间天津市大气污染治理重点工程实施对天津市PM2.5空气质量改善的贡献。结果显示,热力供应、工业燃煤及居民生活源是天津市PM2.5污染主要贡献来源。重点工程全部实施完成后,天津市PM2.5空气质量浓度值与2010年相比约有11.5%的下降,对改善天津市空气质量效果显著。
The survey of pollution source in 2010 was used as the main data to establish the Tianjin air pollutant emission inventory.The months of January,April,July and October in 2010 were selected to represent winter,spring,summer and autumn,respectively.The seasonal change of PM2.5source composition was simulated and the contribution to air quality improvement by the implementation of key air pollution control projects in Tianjin was evaluated with the MM5/CMAQ model during the 12th Five-Year Plan Period.Results showed that heating power supply,industrial coal burning and domestic pollution source were the three main sources contributing to PM2.5pollution in Tianjin.The PM2.5concentration in Tianjin would have been decreased by 11.5% compared to that in 2010 after the implementation of all key projects.This will significantly improve air quality in Tianjin.
