森林流域生态水文过程动力学机制与模拟研究进展

水文过程是联系气候变化和森林生态系统时空变化的关键因素．未来的气候变化和人类大尺度活动将影响森林流域生态系统与水文过程的变化，森林流域生态与水文过程耦合、生态系统水文过程动力学机制研究在认识和调控生态资源及其合理利用、区域生态恢复，以及社会经济可持续方面均具有重要意义．森林流域生态系统中的水文过程可分为降雨截留、蒸散和产汇流过程．森林流域生态与水文耦合过程边界条件的确定，土壤表面特定水文过程的参数化，降雨、土壤水分运动和植被的动态耦合作用，分布式模型的应用以及森林生态水文过程动力学机制与调控等将是今后生态水文动力学过程研究的重点，综述了森林流域生态水文过程动力学机制与调控的研究进展。

Research advances in dynamic mechanism and its simulation of eco-hydrological process in forest catchment

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.
