摘　　要：通过对沈阳市浑河流域水环境的调查,基于Mike11与EFDC建立浑河流域沈阳段水动力-水质耦合模型,并对突发污染事故进行模拟研究。结果表明,Mike11与EFDC模型应用于浑河流域的预警模型在率定期和验证期的模拟结果均良好,所确定的参数能准确反映河道特征。因此,此预警模型可应用于浑河流域突发性水环境风险应急预测,并且能够对浑河污染物迁移转化过程进行准确模拟预测,模拟结果能够为区域水资源管理和保护提供技术支持,达到流域应急预警功能需求。According to survey water environment of the Hunhe River in Shenyang City, it established the hydrodynamics- water quality coupling model of the Hunhe River in Shenyang section based on Mikell and EFDC models and studied the simulation of sudden pollution accident. The results showed that the model simulated accurately in calibration periods and verification periods based on Mikell and EFDC models and the determined parameters could accurately reflect the river characteristics.Therefor, the model can be applied to predict the sudden water enrionmental risk in the Hunhe River, and accurately simulated the migration and transformation process of pollutant. The simulation results can provide technical support for the protection and management of regional water resources and meet the requirements of river basin emergency warning.
