闸库调度下太子河流域水量水质模拟及响应研究

Study on quantity and quality simulation and response under dispatching of water gate and reservoir in Taizihe river basin

鉴于太子河流域水资源调控程度高、水污染严重、河流健康状况日趋恶化等特点,在综合考虑各种因素的基础上。采用一维水量水质耦合模型,模拟了太子河典型年的水动力和水质时空分布,系统分析了水文与污染负荷耦合的环境过程。在此基础上,根据太子河流域现状提出不同库群调度方案,评估了各方案下太子河的水质响应过程及其对沿程各站点水质环境的影响。

According to high dispatching of water resources,serious water pollution and gradually deterioration of river health in Taizihe basin,the paper simulates hydrodynamic and water quality spatial and temporal distribution of Taizihe basin in typical year and analyzes systematically environmental processes of hydrology coupling with water pollution with one dimension water quantity and quality coupled model.Based on the simulation,the paper puts forward different reservoirs dispatching plans,evaluates water quality response process of Taizihe river in different plans and influence of the plans on water quality environment of stations in Taizihe river.
