GM , ABSTRACT: Atmospheric pollution is influenced by many uncertain factors, such as the content of pollutants, wind, etc., Therefore, one given environment system can be considered as a grey in- formation system. In this paper, According to the monitoring data of atmospheric pollution in Shi- jiazhuang city of Hebei from 2006 to 2011,the data of air pollution of Shijiazhuang in Hebei is treated by used nondimensionalization approaches, and then the impact factors of atmospheric pol- lution of Shijiazhuang city in Hebei are firstly sorted by using the gray correlation degree analysis. Next the grey ( ) 11 GM , model of the atmospheric pollution of Shijiazhuang city in Hebei is for- mulated. By using the achieved models both to simulate and to predict the atmospheric pollution and the trend of the atmospheric pollution in the next two years of Shijiazhuang city in Hebei is predicted based on ( ) 11 GM , model. Finally, according to the prediction data given by the dis- cussed models, the reasonable suggestions for alleviating the atmospheric pollution are proposed.
