| Abstract: | The paper analyses the factors influencing BP network model precision of medium and long term hydrological forecast, among them, the node point number of input layer, the node point transfer function and the choice of the network training mode influences greatly the model precision. Some propositions are putted forward for BP network model parameter optimization of medium and long term hydrological forecast in the light of research result. |
