摘要
通过建立与垂向平均的二维非恒定和谐型水动力模式相耦合的保守型水质跟踪预报模型,模拟了辽东湾海域的水体交换能力及无机磷和化学耗氧量的平面实时分布状况。给出不同典型时刻下辽东湾海域的潮流场、水体半交换时间及浓度场的计算结果,据此对辽东湾的水体交换性能和污染物的对流输运状况进行分析评价。最后,将其保守型水质预报模型应用于普兰店湾海域的典型渔业污染事故中,验证了该模型处理实际问题的有效性。
The conservative track prediction model of water quality was established through vertical averaging of two-dimensional unsteady hydrodynamic model of harmonious coupling, and simulated the water exchange capacity and profile of dissolved inorganic phosphorus （DIP）, and chemical oxygen demand （COD） levels in Liaodong Bay. The exchange properties of water exchange capacity and convective transport of pollutants in the Liaodong Bay was evaluated based on the calculation of tidal field, half exchange time and concentration field in Liaodong Bay at different time. Finally, the conservative track prediction model of water quality was applied to forecast fishery pollution accidents in Pulandian Bay in coastal Dalian, with validity of the model for dealing with the actual issues.
