Abstract:Process-based modeling is an effective way in the current eco-hydrological stu dy to explore the interacting mechanism of ecological and hydrological processes in relation to forest vegetation. Because of the nonlinearity of terrestrial ec o-hydrological processes and diversity of scales, the process-based distribute d hydrological models based on slope or small catchments can not be used to make an explicit prediction for large scale watersheds. More over, the eco-hydrolog ical function of forest vegetatio...
