Comprehensive Analysis Of Air Quality In Hebei Province

With the rapid economic development and the accelerated pace of urbanization, human activities emit large amounts of polluting gases, which cause air quality problems gradually worsened, especially in developed areas and urban agglomerations. A sharp deterioration in air quality had a tremendous impact in our national economy and social life. Now, the high frequency of occurrence of haze, serious wide ramifications, the unprecedented degree of contamination. People pay more and more attention to the air quality, which is very important to prevent and reduce the occurrence of fog and haze. The paper select the number of days which reach the air quality and better than the second level in Hebei Province in 2003-2012and the major pollutants sulfur dioxide, nitrogen dioxide, respirable particulate matter research factor on the status of air quality and changes in the characteristics of descriptive analysis, to do the comprehensive evaluation of the air quality in Hebei Province. In view of the seriousness and danger of PM2.5 pollution, using the correlation analysis of PM2.5 and other five kinds of the concentration of pollutants to do the regression analysis to determine what kind of linear relationship between pollutants and PM2.5 were the most significant, so as to provide a theoretical basis for the source of PM2.5 emissions and emission control of PM2.5. The influencing factors of urban air quality are analyzed in detail, which provides the basis for the selection of input variables to establish the model of the influence factors of air quality.Selected ten representative factors as evaluation factors, using the method of grey correlation analysis, doing correlation analysis between the ten representative factors and three kinds of major pollutants factor,Analysis the impact factors of air quality in Hebei province’s, and accordingly put forward relevant suggestions to improvement of the quality of air in Hebei Province.
