摘　　要：由于社会经济的快速发展,某平原河网区城市水质受到较大影响,已达不到水功能区要求的目标,计划采取建闸引水方式改善城区水质。为了分析建闸引水的效果,采用一维水动力-水质模型,针对不同枢纽布置和引水规模,以40a的历史实测水文资料进行了分析。根据分析结果确定了能够使城区满足水功能区目标要求的最佳引水量,提出了最优枢纽布置及引水方案。Along with quick social and economic development, the water quality of a city in the plairL river network area is influenced seriously and the water quality can not meet the management goal of water function requirement, so a water diversion project is planned for improving the water quality. In order to analyze the improvement effect by projec, t water diversion, in the light of different project layouts and water diversion scale, a 1D hydraulic and water quality model is applied to analyze the water quality variation condition with 40 -year hydrological data. According to the analysis result, the optimized water diversion flow that makes the water quality meet the management goal of water function area is determined and the optimized project layout and water diversion scheme is proposed.
