中文摘要:

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。

英文摘要:

A new multi-parameter optimal inversion method was established by the coupled method of genetic 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 observation 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.
