中文摘要：

分布式水文模型是探索和认识复杂水文循环过程和机理的有效手段,也是解决许多水文实际问题的有效工具。本文从当前水文水资源科学研究的热点问题出发,系统总结了分布式水文模型在解决水文学面临的重要问题中研究与应用的现状、进展与不足,讨论了建模中存在的难点问题和关键技术,并探讨了分布式水文模型的发展趋势。

英文摘要：

Distributed hydrological model is an effective way to investigate and understand the processes and mechanism of complex hydrological cycles,and also an efficient tool to solve practical water problems.At present,water problems including floods,droughts,water pollution and soil erosion,as well as the occurrence of global climate change and digital hydrology,give a great challenge to the studies,development and applications of distributed hydrological models.Proceedings of the key issues in the field of hydrology and water resources,the state-of-the-art,the major progress and problems in studies and applications of distributed hydrological models are summarized.Possible tendency,major difficulties,and key technologies in the development of distributed hydrological models are also presented.
