Abstract: In this paper, the author use modern technology of the artificial neural network to analyse the law of dynamic change of the Chlorine ion in the water of the Yangtze river estuary. With the consider of different controlling water quantity project after the completion of the construction of the reservoir on Three Gorge Upward the Yangtze River, a BP neural network model is used for forecasting the denisity of Chlorine ion in Gaoqiao observation station. The results will be referred to related Shanghai department and water supply corporation for decision-making.

Key words: BP neural network, back-propagation training, the denisity of Chlorine ion, BP neural network, back-propagation training
