摘　　要：论述了流域水文模型结构和参数的水文学基础、物理上的耦合关系,以及集总式流域水文模型与分布式流域水文模型的本质区别,讨论了2种模型解算方法的特点,以及在参数率定中产生异参同效的原因和减少异参同效影响的措施;提出了一个比较客观的模型验证和相互比较的方法。The hydrological principle of the structure and parameters of watershed hydrological models,the physical coupling relationship between the structure and parameters,and the essential difference between lumped and distributed watershed hydrological models were investigated. The characteristics of the solution methods for these two models,and the reasons causing the phenomenon of equifinality for different parameters during the calibration of the watershed hydrological models,as well as methods to alleviate the effects of this phenomenon,are discussed. A method for verification and comparison of the watershed hydrological models is proposed.
