以青海省德令哈市人工湖为例，介绍了MIKE水动力-水质耦合模型在人工湖引水流量及湖体形态优化设计中的应用情况。通过对人工湖形态的网格划分，在大量模拟方案的基础上，系统模拟了人工湖不同点位的水体交换完成时间，确定了2条引水渠道的引水流量和引水周期；通过人工湖“新”、“老”水体的对流扩散模拟，确定了湖体重污染潜在区域和富营养化高发区，为湖体形态和水体流态的优化提供了重要技术支撑；通过对风场叠加方案的模拟，为工程运行期间换水时机的选择提供了关键的参考依据。

Taking the artificial lake at Delingha City in Qinghai Province for an example,this paper introduced the application of hydrodynamic wa-ter quality model in the optimization designs of the flow of water division and overall morphology of the artificial lake. Utilizing the most advanced MIKE hydrodynamic water quality coupled model and meshing the artificial lake,this paper systematically simulated the completion time of water exchange of different points in the artificial lake and determined the water division flow and water cycle of two division channels,based on a large number of modeling schemes. By the simulation of the convective diffusion between the new and the old water body in the artificial lake,this paper determined the potential severe pollution area and high incidence area of eutrophication,which provided technical support for the optimization de-sign of lake morphology and water flow pattern. Meanwhile,by the modeling of the wind field overlay scheme,this paper provided reference basis for the water exchange time selection in the project running period.
