Application of Artificial Neural Network to Air Pollution Prediction in Suzhou City

The artificial neural network has been widely used in the forecast and prediction due to the development of its theorectical basis and computer technology. The basic principle of BP neural network is briefly introduced, and the applications of BP neural network to air pollution prediction in China are reviewed in detail. It is applied to predict SO2 concentration in Suzhou, and it is shown that BP neural network is easy to implement and gives quite accurate results, and that it can also be used to predict other air pollutants such as PM10, NOx, and so on.
