To perform smog forecast,this paper puts forward a model,which is based on support vector regression(SVR)method and GA method.The first eigenvector dimension is reduced using factor analysis,and the SVR parameters are optimized through the GA method,and put into the SVR model for the prediction of the PM2.5 value of the city of Baoding.Through comparison, an optimized prediction model is obtained.
