Abstract
The main sources of urban atmospheric particulate pollution are industrial emissions,traffic exhaust,urban dust,secondary aerosols and regional transport,which seriously threaten public health and ecological environment.Therefore,it is necessary to carry out ultra-low emission transformation,adjust transportation structure,strengthen dust control,promote coordinated emission reduction of precursors,and strengthen regional joint prevention and control.The emission characteristics of five types of pollution sources are systematically analyzed,the emission reduction strategies are proposed,and then taking a typical inland industrial city as an example,combined with a chemical mass balance model,the effectiveness of each measure is quantitatively evaluated.The results show that the annual average reduction rate of fine particulate matter(PM2.5)concentration in the multi measures collaborative intervention group is about 40.6%,and the comprehensive emission reduction effect is significant.关键词
