Eco-hydrology groundwater-dependent of ecosystem

In a changing environment, altered groundwater flow regime would affect ecohydrological pattern and processes, to result in degradation of ecosystem. Here we review major progress in ecohydrological research of groundwater-dependent ecosystem. In general, research for groundwater dependent ecosystem has transitioned from interaction between groundwater and ecosystem to interaction between multi-elements, multi-spatial and temporal scales, with more focus on interaction between surface water, groundwater and ecosystem. Future research should stress the following themes: identification of groundwater dependent ecosystem, exploring evolution mechanism, classification of groundwater dependent ecosystem. The following should also be stressed: ecological water requirement of groundwater dependent ecosystem, comprehensive simulation for ecohydrological elements and processes, construction of groundwater dependent policy to restore and protect groundwater dependent ecosystem.
