摘　　要：基于MIKE ZERO 2020软件中的HD水动力学模块和AD对流扩散模块,建立郁江贵港市河段的水文、水质信息耦合模型,对郁江贵港河段的水位、流量以及污染物在水体中迁移扩散衰减情况进行了模拟分析。根据郁江近年来的水文资料对模型进行率定并验证。将该模型应用于2023年6月21日~7月6日的洪水过程,结果表明,所建立的模型在率定和验证及应用期间模拟效果均表现良好,模拟精度高。充分证明该模型适用于模拟郁江贵港河段的水文、水质信息变化特征,为提高贵港市防洪、水情预报及水污染预测提供了重要的技术支撑。Based on the HD hydrodynamic module and AD advection-diffusion module of MIKE ZERO 2020 soft⁃ware,a hydrological and water quality information coupling model was built for the Guigang section of Yujiang Riv⁃er.The water level,discharge,migration,diffusion and attenuation of pollutants in water bodies of Guigang section was simulated and analyzed.The model was calibrated and examined according to the hydrological data of Yujiang River in recent years.This model was applied to the flood process from June 21 to July 6,2023.The results demon⁃strate the simulation effect of this model is good during calibration,verification and application with high simulation accuracy,fully proving that the model is suitable for simulating the characteristics of hydrological and water quality information changes in the Guigang section of Yujiang River,and is able to provide important technical support for improving the prediction of flood,regime and water pollution in Guigang City.
