| 中文摘要: |
| 本文在总结大量洪水预报实践经验的基础上，提出了一种峰值识别理论及相应的改进BP算法(Error Back Propagation with Peak Recognizer,简称BPPR).该理论及算法在修改网络权重时，偏重大值误差，即大值误差对权重的修改起主要作用.这种BPPR算法使人工神经网络洪水预报模型对洪峰的预报精度显著提高，从而保证了洪峰预报的可靠性. |
| 英文摘要: |
| A modified BP algorithm with peak recognition theory (BPPR) is proposed for improving the calculation of artificial neural network. By this algorithm the error correction of flood peak value is mainly depending on the modification of weight according to the error of the big values. It is useful to improve peak value recognition the accuracy of flood forecasting. |
