非线性遗传优化海域水质耦合模型多参数反演方法研究

Inversion method of Multi-parameter for coupling model of marine water quality with nonlinear genetic optimization

通过遗传算法和海域水质模型的有机耦合,提出了基于非线性遗传优化海域水质耦合模型多参数反演的新方法。将海域水质模型嵌入遗传算法模型中,以海域内部验证点位的误差函数为适应度,进行模型多参数的优化反演。文中以渤海湾海域水质模型多参数反演的"孪生"试验来验证方法的有效性。数值结果表明:该反演新方法具有较高的精度。

A new multi - parameter optimal inversion method was established by the coupled method of ge- netic algorithms and marine water quality model. In this method, marine water quality model was inverted into the genetic algorithms model for multi - parameter precise inversion by the fitness error function of ob- servation stations. Case study in the Bohai bay by twin experiments was presented for validating the present method. Verification results show the coupled inversion method has higher simulation precision.
