主　　题：Fuzzy comprehensive evaluation Grey theory GM( 1,1 ) Air quality in Baoding City 

摘      要：Nowadays,the quality of the air environment is closely related to the health of the ecosystem and the safety of people living. With more and more attention attached to the quality of the air environment,it is imminent to analyze the future development trend of air quality. In this paper,the grey correlation analysis was used to determine the weights of 6 pollution indexes,namely PM10,PM2. 5,SO2,NO2,CO and O3. The fuzzy comprehensive assessment method was applied to determine the air quality eigenvalues H（ 2. 145,1. 926,and 1. 805） of Baoding City in 2014-2016,suggesting that the air quality in Baoding is getting better and better. In addition,the grey forecasting model GM（ 1,1） was used to forecast and test the air quality of Baoding City. The results show that the prediction is good.
