摘　　要：针对太湖流域存在的主要水问题,在引江济太原型试验引分水控制模式分析的基础上,建立了区域水量水质模拟与调度的耦合模型。针对模型优化的复杂性,对水量水质数值模拟的格式算法、优化调度的目标函数及约束条件、模拟与优化模型的协调衔接等关键环节,提出了合理可行的处理方法。应用研究中,针对引江济太原型试验中暴露的引水分配不合理问题,研究了特定时段内望虞河引水的合理调度,并重点分析不同工况下调水对太湖水生态环境的影响。计算结果表明,所建立的模型是可行的,对区域水量水质联合模拟与调度有一定的借鉴价值。Based on the analysis of control pattern of water diversion on the Yangtze River-Taihu lake water transfer prototype test, a model coupling water quantity and quality simulation and schedule is established to study the main water problem of Taihu basin. In view of the complexity of the model optimization, some rational and feasible solutions are put forward in the key links, including mainly the algorithm of the water quantity and quality numerical simulation model, the objective function and the constraint condition of the optimal operation model, and the coordination and connection between the simulation model and the optimization model. Aiming at the irrational distribution of the water diversion in the Yangtze River-Taihu lake water transfer prototype test, the rational scheduling mode of the water diversion from Wangyu river in special time period is studied, and the effect of the water diversion on the ecological environment of Taihu lake under different working conditions is emphatically analyzed. Results of the case study show very good feasibility of the methods above, and also provide theoretical reference for the quantitative study of the cross-regional integrated regulation of water quantity and quality.
