摘    要:平原感潮河网河道密集、水动力学条件复杂,不同条件下水环境状况及影响比较难模拟和定量评价。利用M IKE11软件建立东江三角洲水环境综合模型,可充分利用三角洲河网实测资料建立流域水力学模型、主要污染物运移规律和自净、富集规律的水质模型,并对模型进行率定和验证。利用其进行东江下游及三角洲供水水源保证工程不同布置方案实施前后对东江三角洲区域水环境影响效果模拟分析。通过应用表明,该模型能较好模拟东江三角洲在不同条件下的水环境变化,评价结果可以为该区域水环境保护和水资源管理提供科学依据。

关 键 词:水环境综合模型  水动力  水质  东江三角洲  平原河网

Abstract:The plain tidal waterways were densely distributed and the hydrodynamics requisitions were complicated.The water environment under various conditions was difficult to be simulated and quantitatively evaluated.The comprehensive model of the water environment in Dongjiang River delta region was developed on the base of the MIKE 11 software system.This model took full advantage of the delta region network field data to constitute the hydraulics model and the water quality model simulating the movement law,self-purification and concentration of the key pollutant.This model was calibrated and verified.The environmental impacts,before and after the implementation of the different deployment schemata of the water-supply source development down stream Dongjiang River and delta region,on the water environment in Dongjiang River delta region were simulated and analyzed.The application indicates that,this model could preferably reproduce the water environment variation under different conditions in Dongjiang River delta region and the outcome could provide the regional water environmental protection and water resource management with the scientific support.
