Nowadays, the continuous fog and haze weather has made people more and more concerned about air pollution.And the air pollution problem in the Beijing-Tianjin-Hebei region is the highest in China. The high-density population distribution, crowded urban traffic and large-scale heavy industry bases are the main reasons for this phenomenon.This study analyzes the problem of air pollution sources and changes on gradient of air concentrations. Based on quantitative analysis, variable control, linear fit and two order parabolic partial differential equation,the principal component analysis model and Single Gaussian plume diffusion sources model are developed. Coupled with these models, MATLAB and Microsoft Excel are also further made use of to analyze the gradient of pollutant concentration around the plant at different time and judge the air quality level.Finally, it can be concluded that the main sources are industrial emissions, fuel combustion, vehicle exhaust and industrial waste water as well as the main influencing parameters are PM2.5 and PM10.0. And the farther away from the chimney, the lower the concentration of Nitrogen oxides was.The model is suitable for analyzing the influence of pollutants emitted from plant chimneys on the surrounding area.It can also help the Environmental Protection Department to formulate emission standards to promote sustainable economic development.
