本文对地下水与地表水联合调度过程中， 联合调度系统类型划分、管理模型中目标函数的选择以及复杂系统的优化等问题进行了探讨。提出了新的联合调度系统分类方案，指出对于复杂的地下水－地表水联合调度系统， 其优化方案的确定， 不仅需要利用多种优化方法求解， 而且还必须对求得的优化解进行模拟验证。最后给出了宁波剡江流域地下水与地表水联合调度的实例 In this paper, the joint scheduling of groundwater and surface water, the classification of the joint scheduling system, the selection of the objective function in the management model and the optimization of complex systems are discussed. A new joint scheduling system classification scheme is proposed. It is pointed out that for the complex groundwater - surface water combined scheduling system, the optimization scheme must not only be solved by many kinds of optimization methods, but also must be validated by the optimized solution. Finally, an example of joint regulation of groundwater and surface water in Ningbo Qijiang River Basin is given
