摘要 对新安江模型进行了简要介绍,对函数曲面参数率定方法的基本原理和率定过程进行了详细阐述。在水吉流域,运用函数曲面参数率定方法对新安江模型的5个敏感参数进行率定,在实际应用中检验方法有效性。结果显示,在理想模型和实际模型中,该方法都能稳定率定得到优值。所以,该方法是一种很有效的新安江模型参数率定方法。 The Xinanjiang runoff model is briefly introduced, and the parameter estimation method based on parameter Junction sur face is described and analyzed. The method is applied to calibrate the Xinanjiang runoff model in Shuiii basin. Both for the ideal mod el and the actual model, the stable and best value of model parameters can be obtained. The results show that the parameter estima tion method based on parameter function surface is not influenced by the different initial value of parameters and has global conver gence, high precision and efficiency. The method is proved to be an effective parameter estimation method by the application.
