摘　　要：针对闸控潮汐河网区的水系条件和水动力特征,立足于水网区水环境改善的需求,构建了闸控潮汐河网区水环境调度模型。该模型由河网区一维水动力模型、河网一维水质模型和水闸调控模拟模型3个模型构成,采用实测资料对模型进行了率定和验证。选择珠江三角洲"中珠联围"作为研究区开展实证研究,提出了联围整体调度与局部重点改善相结合的调度方法。结果表明,统筹考虑中山和珠海的调度需求,实施"中珠联围"统一调度,形成"西北进、东南出"的水流格局,可有效地加快联围内河涌的水体更新速度,降低污染物平均浓度,对于"中珠联围"水环境的改善及供水水质安全的保障具有重要意义。Aiming at the water conditions and hydrodynamic characteristics of tidal river net controlled by sluice gates,basing on the requirements of water environment improvement in water networks,this thesis is to construct the water environment dispatching model of tidal river net controlled by sluice gates.This model consists of three modules of one-dimensional hydrodynamic model and one-dimensional water quality model for river networks and sluice-controlled simulation model,and measured data are used for the calibration and verification of this model.Selected the levee of Zhongshan and Zhuhai of Pearl River Delta as the research district for empirical research,dispatching method of combination of overall dispatch and key-point improvement of embankment connections is proposed.The results show that the overall consideration of dispatch requirements of Zhongshan and Zhuhai,the implementation of the Pearl River Delta planning,and the formation of northwest-in-and-southeast-out flow pattern,are important to speed up the water update of the rivers in the embankment connections,decrease the average concentration of pollutants,improve the water environment of the levee of Zhongshan and Zhuhai,and assure water supply quality security.
