摘　　要：流域生态水文模型是全球变化下流域生态水文响应研究的重要工具,通过定量刻画植被与水文过程的相互作用及全球变化对流域生态水文过程演变的影响机制,为流域水资源管理和生态恢复提供科学支撑,是生态水文研究的前沿和热点。基于植被与水文过程相互作用规律,流域生态水文模型一方面要充分描述植被与水文过程相互作用和互为反馈机制,另一方面要精确刻画流域的空间异质性。本文在分析流域尺度陆地植被与水文过程相互作用特点的基础上,将现有流域生态水文模型进行归纳和分类,剖析不同类型模型的优缺点,并总结现有模型应用的代表性研究成果,最后,对流域生态水文模型存在的关键问题(如植被与水文相互作用机制的描述、模型参数的估计、模拟结果的不确定性分析等)进行讨论。Eco-hydrological model of watershed scale is an essential tool to assess the impact of environmental change on watershed hydrological and ecological processes. This has made eco-hydrological model a hot research focus, and significant advances have been achieved during recent years. This paper provides a perspective on the current state of the research on eco-hydrological modeling. Firstly we elaborate the characteristics of the interaction between vegetation and hydrological processes and the requirements for watershed eco-hydrological modeling. Then the existing models are classified according to the detail levels of their description of the eco-hy-drological interaction. Different types of eco-hydrological models and their respective advantage and disadvantage are summarized. Finally, the key problems and research issues （i.e, eco-hydrological interaction, parameters estimation and the problem of uncertainty） for eco-hydrological modeling are addressed.
