摘要
The present invention discloses a small-scale air quality index prediction method and system for a city. The method comprises: firstly dividing a city area into a grid of multiple locations to undergo prediction; acquiring historical data related to each model and creating the following models on the basis of the historical data: a time prediction model respectively corresponding to a prediction relating to a current moment and predictions relating to each moment in a future period of time, a spatial prediction model for performing air quality predictions with respect to locations at specified coordinates, a dynamic prediction model for characterizing a relationship of traffic data and data of a geographical location of interest to an air quality index, and an indoor and outdoor prediction model for characterizing a relationship of an indoor air quality index to an outdoor air quality index; when performing prediction, performing coordinated training on the created time prediction model, the spatial prediction model, the dynamic prediction model and the indoor and outdoor prediction model with respect to any one of the locations to undergo prediction at any real-time moment, so as to merge prediction results of all of the models and obtain air quality index predicted values of each of the locations to undergo prediction at a corresponding current moment, and at each moment in the future period of time.
