| Abstract: | 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. |
