Study on the variation law of atmospheric quality and the mutual influence between regions

摘要

In this paper, to establish the mathematical model of Beijing Tianjin Hebei region air quality change existing data analysis and processing analysis, air quality in the region between the mutual influence relations. Finally, according to the analysis results, this paper puts forward the methods and measures of air pollution. Time series model of air quality change in different cities. The ARIMA model is not strong enough to use the wave period. Based on the diffusion principle of air pollutants, the partial differential attenuation dispersion model is established, and the simulation results are very good.
