Abstract: Hydrological process is the key link between climatic fluctuations and ecologic dynamics of forests at spatial and temporal scales.To some extent,global climate change and large-scale human's activities will impact the spatial-temporal changes of eco-hydrological process in forest catchments in the future.Therefore,researches on the dynamic mechanism of eco-hydrological processes in forest catchments play a crucial role in understanding and controlling the rational use of ecological resources,resuming regional ecology,and sustainable development in economy.This paper described the interception,evapotranspiration and rainfall-runoff of forest ecological system and their effects on hydrological process.The spatial structure of soil moisture and its evolution with time were also the cause and consequence of forest.The spatial-temporal interaction between hydrologic and ecologic dynamics,the application of distributed hydrological model,and the eco-hydrological dynamics and cybernetics of forest would be the most exciting frontiers of the relative researches in the future.
