In order to better understand the impact of vegetation restoration on hydrological processes, the SWATMODFLOW model and dynamic HRU was coupled, and LU-SWAT-MODFLOW model was developed to accurately simulate the dynamic change of vegetation and groundwater in the lower reaches of the Bayin River Basin. The results revealed that the LAI, ET and groundwater level simulated by LU-SWAT-MODFLOW model are better; After vegetation restoration in the study area, the monthly evapotranspiration of different sub-basins increased by 0-1.5 mm, and the annual evapotranspiration increased by 0-6 mm; The average monthly groundwater recharge increased about 1.27 mm, and the average annual groundwater recharge increased 14.02 mm. The exchange of the surface water and groundwater in the study area have obvious changes in the areas where the vegetation restoration type is low-coverage grassland and bare land converted to forestland.
