Abstract： Aiming at the large error of the current air quality prediction model and the fact that a single model has certain limitations in different aspects, resulting in large prediction error, an adaptive boosting combination model is proposed. Five methods, including the squared error sum reciprocal method and the simple weighted average method, are used to adaptively assign weights to the three basic boosting models. The final result is superimposed according to the corresponding weights, to give full play to the advantages of each single model and improve the prediction accuracy. The experimental results show that, the combination of squared error and reciprocal method performs optimally, and the weighted combinatorial model using the error squared and reciprocal method was calculated with MAE 7.124 4, RMSE 9.367 1, and R2 as 0.863 9,，better than other weighting combination methods and a single boosting model. The application of this combined model provides an effective method for optimizing air quality prediction systems.
