摘要
The decision support technology platform for air pollution prevention and control was applied to quantify the effects of the implementation plan of the 'Ten Measures' for air pollution control in Jinan. Furthermore, the optimization and cost-benefit assessment of air pollution prevention and control strategy were carried to reduce the ambient ρ(PM2.5) and ρ(O3) by 20% and 8%, respectively, in 2018 compared with 2017. The results show that: (1) After the implementation of the 'Ten Measures', the reduction rates of SO2, NOx, VOCs, and primary PM2.5 were 39%, 24%, 42%, 41%, respectively, and this scenario could reduce the ρ(PM2.5) in Jinan in 2018 by 19% compared with 2017. The additional cost of pollution control was about 4.70×108 RMB, and the benefit/cost ratio was 1.40. The reduction of local dust emissions with the lowest reduction cost per emission contributed the most to the reduction of ρ(PM2.5). Therefore, it is recommended to further strengthen the emission reduction of dust sources in the next stage in Jinan City. (2) The reduction rates of SO2, NOx, VOCs, primary PM2.5 obtained through inverse computation of strategy optimization were 46%, 20%, 42%, 60%, respectively, and the additional cost of pollution control was about 4.69×108 RMB under this strategy. Compared with the 'Ten Measures', the optimization strategy increased the emission reduction rates of SO2 and primary PM2.5, and decreased the reduction rate of NOx that has a negative effect on O3, which meets the air quality target while reducing the cost of pollution control as much as possible, and the benefit/cost ratio was improved to 1.88. The successful application of the technology platform in Jinan provides an empirical scientific basis for air pollution prevention and control in the next stage in Jinan City, which has demonstration significance for the gradual promotion and use of the technology platform in other cities in China. It can efficiently support comprehensive and scientific decision-making on air pollution prevention and control. ? 2021, Editorial Board, Research of Environmental Sciences. All right reserved.
