A Simulation-Based Research on the Hydrological Response of Land Use/Cover and Vegetation Changes at Watershed Scale

摘要

This paper presented a researeh on the hydrological responses of land use/cover and vegetation changes on watershed-scale under the background of human activities using physically-based and parameter-distributed hydrological model SWAT. Leaf area index calculated by remote sensing data was used in this simulation to express the watershed vegetation situation. Variable-controlled simulating method was used to simulate the responses of watershed hydro-characteristics and hydro-processes to land use/cover and vegetation changes.
