Based on the results of PM2.5 sources analysis, this paper analyzes the component evolution, formation causes, and governance countermeasures of urban haze in Beijing. The proportion of coal burned in sources of PM2.5 in Beijing has gradually declined, and motor vehicle exhaust has become the largest source of pollution. The formation of haze pollution in Beijing is related to the change in energy structure, the increase in the number of motor vehicles, the increase of urban construction area, and the cross-regional transmission of pollutants in Hebei, Tianjin, and other places. Beijing’s urban haze control measures include reducing vehicle emissions, optimizing industrial structure, adjusting energy structure, building an eco-city, and implementing cross-regional coordinated governance.
