摘要: Vegetation influences the runoff through affecting rainfall interception, soil water infiltration capacity and surface evaporation and other factors etc. In this paper, remote sensing data is used to analyze the major vegetation types of Poyang Lake Basin, and then a hydrological model (VIC model) is employed to simulate and compare runoff under different vegetation type scenarios. The simulation results show that the presence of vegetation will reduce the runoff and rate of decrease varies according to vegetation type: runoff reduction reaches the maximum when the vegetation type were mixed forest, followed by evergreen coniferous forest follows, and reaches the lowest when the evergreen broad-leaved forest predominates.
