采用傅里叶级数频率分解特性将总径流包含的3种不同频率水源分离,构建了不同水源间参数独立且和频率相关的目标函数,通过理想模型的实例分析验证了该方法的可行性。结果表明,该方法信息量增加,实现了汇流参数分层分频率定,解决了汇流参数率定的局部优值、率定结果不稳定和不合理问题。
The Fourier series frequency decomposition is used to separate the water sources of three different frequencies contained in the total runoff. Independent and frequency-dependent objective functions are constructed for different water sources. The feasibility of this method is verified by an example of an ideal model. The results show that the method increases the amount of information, realizes the stratified frequency division of the bus parameters, solves the local optimal value of the bus parameters, and the rate set results are unstable and unreasonable.
