Abstract: The global climate is warming significantly over the past 100 years,temperatures in the future will rise,and the patterns of precipitation will be altered.Based on a comprehensive literature review,this study summarizes the research status of wetland ecohydrology from three aspects:The impacts of climate change on wetland hydrology and water resources,the interaction of wetland hydrology and ecology under the influences of climate change and wetland ecohydrological models.Over a long period,wetland ecohydrology only focuses on the ecohydrological process,however,it has been moving to the direction of an interdisciplinary science integrating interactions of climate,ecology,and hydrology.At present,studies on the interaction between wetland hydrology and ecology is mainly focused on the oneway coupling analysis,e.g.,the impact of hydrological processes on vegetation.It has been a lack of researches on the interaction mechanism between the wetland hydrological process and the ecological process under the influence of changing climate.The impact of climate change on wetland ecohydrology has become a scientific issue,and deserving a quick action from the hydrological research community.The physicallybased modeling approach is expected to be the most important tool in predicting the wetland ecohydrological response to the future climate change.
