摘　　要：建立福州市江北城区内河水系水动力水质耦合模型,利用SCE-UA算法对水闸调度参数进行优化。结果表明,SCE-UA算法可用于水文模型参数的率定和河网水系水闸调度系统优化参数的识别。在待优化的区域单独建模,将生态补水规划模拟计算结果为优化区域提供边界,结果使模型计算时间大大减少。将优化后的参数代入原模型进行检验,效果令人满意。A coupled hydrodynamic and water quality model was established for the urban inland river network of Fuzhou City.The SCE-UA algorithm was used for the optimization of the sluice operation parameters.The optimization results show that the algorithm can be used to calibrate hydrologic model parameters and recognize the optimized parameters of the river network＇s sluice operation system.The region to be optimized can be modeled individually,using the boundaries provided by ecological replenishment planning simulation results,and the optimization time was reduced greatly.The results of the test of the optimized parameters in the original model were satisfactory.
