摘要:
研究以江苏沿海盐城感潮河段射阳河为对象，构建适用于射阳河的水动力-水质-泥沙耦合模型实现水量、污染物浓度和泥沙淤积的变化过程模拟，利用构建的水动力-水质-泥沙耦合模型核算河道水质达标和冲淤保港的生态需水量，并与改进生态水力半径法计算的基本生态环境需水量进行比较，进而最终确定射阳河挡潮闸闸上闸下的生态环境需水量。研究结果表明：构建的研究区水动力-水质-泥沙耦合模型能够有效模拟射阳河水动力、水质及泥沙淤积变化过程，符合模拟精度要求；射阳河闸上汛期生态环境需水量为348 m3/s，闸下非汛期生态环境需水量为205 m3/s。研究成果可为江苏感潮河流生态环境需水核算、生态系统健康保护与修复提供参考。
Abstract:
The study focuses on the tidal section of Sheyang River in Yancheng, Jiangsu Province. A hydrodynamic-water quality-sediment coupling model suitable for Sheyang River is constructed to simulate the changes in water quantity, pollutant concentration, and sediment deposition. The constructed hydrodynamic-water quality-sediment coupling model is used to calculate the ecological water demand for river water quality compliance and erosion and sedimentation protection, and compared with the basic ecological environmental water demand calculated by the improved ecological hydraulic radius method. Finally, the ecological environmental water demand above and below the Sheyang River tidal barrier is determined. The research results indicate that the constructed hydrodynamic-water quality-sediment coupling model in the study area can effectively simulate the changes in hydrodynamics, water quality, and sediment deposition of the Sheyang River, meeting the requirements of simulation accuracy; The ecological water demand during the flood season above the Sheyang River sluice is 348 m3/s, and the ecological water demand during the non flood season below the sluice is 205 m3/s. The research results can provide reference for the ecological environment water demand accounting, ecosystem health protection and restoration of tidal rivers in Jiangsu.
