摘　　要：针对目前嘉兴市区河道水质调度缺乏科学支撑的问题,利用嘉兴市最新水文、水质和水利工程信息,应用MIKE 11构建了嘉兴市区一维河网水动力水质耦合模型。模型的水位模拟误差平均为3.4 cm;以实测值的30%作为许可误差,河道水质浓度的模拟准确率达到86.7%,模型精度较高。应用所构建的模型,评估现状调度方案的水质改善效果,提出优化调度原则,探索优化调度方案。结果表明,与没有调度相比,现状调度方案可提高水质3.8%;基于文中提出的优化方案,可提高9.8%。研究成果可为嘉兴市区河网的水质改善提供科学支撑。Coupled one dimensional water quantity and quality model based on MIKE 11 was established for the urban river network of Jiaxing City with the latest hydrologic,water quality and water resources project information,in order to provide scientific support for the river water quality regulation in the City.The model showed good performance with water level error of 3.4 cm in average and concentration accuracy of 86.7%with permissible error of less than 30%compared to the measurements.The current water quality regulation scheme was evaluated and the optimal one explored with proposed principles with the established model.The results indicated that compared with no regulation scenario,water quality was improved by 3.8%with current regulation scheme and 9.8%with the optimal scheme that was proposed by the study.The study results would provide important support for water quality improvement of the urban rivers in Jiaxing.
