函数曲面参数率定方法在SAC模型中的应用
Application of parameter calibration method based on parameter function surface in SAC model
摘要
Abstract
Both traditional optimization algorithms and modern optimization methods calibrate parameters based on the objective function surface,and most of the objective functions are error sum of squares. Intui-tively, objective function surface based on error sum of squares are more complex than parameter function surface. In addition,those algorithms are often unable to prove the optimal values what they found are glob-al optimal values, and the calculation procedure are complicated and inefficient. As a result, the parameter calibration method based on parameter function surface is put forward and applied to calibrate the parame-ters of SAC ideal model and actual model. First of all,the viability of the method was verified by the ide-al model. Then,the application effects of the method were verified in actual model through 13 years’daily hydrology datum and records of 13 floods in the Dongzhang River basin. The Results in this study indicate that the method is feasible, high efficiency and high precision in practical application. Therefore, it is a useful method of parameter optimization.关键词
