摘　　要：水文过程和生态过程的时空耦合机制 ,是管理水资源和维持生态系统健康运行的关键机理 ,将成为未来研究的前沿领域 .生态水文学是描述生态格局和生态过程的水文学机制的一门科学 .文中简要介绍了生态水文学的内涵、基础理论、主要研究内容和研究现状 ,展望了生态水文学的发展趋势和应用前景 .最后结合西部开发和生态环境建设的有关问题 ,探讨了加强我国生态水文学 。The spatiotemporal linkage between the hydrological and ecological dynamics is one of the keystones to manage the water resources and keep the natural ecosystems run normally, and will be one of the most exciting frontiers in future. Ecohydrology may be defined as a science that studies the hydrologic mechanisms of ecological patterns and processes. Plant water relation is its theoretical basis,soil moisture dynamics and evapotranspiration are its key subject, and scale issues are its critical problem. In this paper, the connotation, basic theories and current main research topics of ecohydrology are briefly described. The current research situation, prospect for the future and application of ecohydrology are also outlined. Finally, how to study ecohydrology with the eco-environmental construction in West China is suggested. For example,first,the hydrological mechanisms of wetlands and lakes,streams and rivers should be better understood in order to guide the conservation of these water resources. Secondly,more efforts on interaction between hydrological dynamics and vegetation establishment should be done to get more useful information for eco environmental construction in West China. Thirdly, water ecological demand should be studied in the inland river basins in arid regions to keep the environment and economics sustainability at the basins.
