The Beijing-Tianjin-Hebei Region's Analysis of Air Quality Assessment

Control air pollution, improve the ecological environment is an important breakthrough of the coordinated development of beijing-tianjin-hebei. So this paper analyzed the air quality of Beijing-Tianjin-hebei, give their comprehensive evaluation analysis. Analysis the pollutant source and get the interaction relations between different regions from analyzing meteorological data. In the process of air quality comprehensive evaluation, using the principal component analysis to handle the six air index, carry on the solution of the characteristic roots and characteristic vectors, to get the comprehensive expression of each component. From the comprehensive expression, we calculate the comprehensive evaluation value of each city and sorting. Using the kriging interpolation method, map out air quality comprehensive evaluation. Using Pearson product to analyze correlation coefficient's influence on the regional air quality between cities, get the interaction relations between different regions. Aiming to guide the practice of environmental protection measures, help to control the atmospheric pollution.
