Abstract

Abstract

Air pollution seriously affects people's production, life and health. Analysis on tempo-spatial distribution of air pollutants and their sources is the basis and prerequisite for air pollution control. Based on the real-time air quality monitoring data, the main pollutant concentration data and meteorological elements data of Jinan from 2014 to 2018, this paper analyzed the spatial and temporal distribution characteristics and sources of air pollutants in Jinan by using correlation analysis method and BP neural network prediction model, and forecasted 6 major pollutants in Jinan.The results showed that the air quality revealed an improving trend year by year. The concentration of the majority pollutants in winter was higher than that in summer, and air quality in non-heating period was better than that in heating period. From the perspective of diurnal variation, the peak period of commuting was the most serious pollution period. Spatially, the pollution of urban periphery was more serious than that of urban. PM₁₀ was becoming the most serious pollutant, and the pollution caused by vehicle exhaust emission was increasing significantly. Strengthening the control of air pollution in suburbs and rural areas, especially the monitoring and control of large particulate matters, and reducing vehicle exhaust pollution by means of vehicle restriction were the main ways to further improve the air quality of Jinan.By prediction result of pollutants concentration, and its analysis for the next three years, we further put forward the pollution control optimization scheme to improve atmospheric pollution in Jinan.
