摘要
利用具有大范围收敛的同伦参数反演方法对水质模型参数进行计算,并应用于北京密云水库总磷的参数反演计算中。通过同伦与遗传反演两种方法分别计算沉降率的误差并进行对比表明,同伦参数反演方法具有良好的稳定性,计算速度快,且初值的选取即使远离目标函数,解仍具有很好的收敛性。
For calculating the water quality model parameters,the large-scale convergence of homotopy parametric inversion method was used and applied in parametric inversion calculation of total phosphorus of Miyun reservoir in Beijing.The authors calculated and compared the error of sedimentation rate by homotopy and genetic inversion methods,which indicates that the homotopy parametric inversion method is good in stability and fast in calculation.And even if the initial selection away from the objective function,the solution still has a good convergence.
