In order to study the law of water resources transformation in the Yimeng Mountain water and soil loss control area, which is under the influence of climate and vegetation cover, the Andi Reservoir Watershed is selected as the research object. The normalized vegetation index (NDVI) is used as an indicator to analyze the spatiotemporal changes of the vegetation cover. Distributed hydrological model SWAT is used to study the spatiotemporal evolution of hydrological elements, and analyze of surface water and groundwater conversion. The results show that, from 2000 to 2016, the NDVI of the watershed showed an increasing trend, of which NDVI increased significantly from 2007 to 2009.Spatially, 84% of the watershed area showed an increasing trend. The SWAT model has a good simulation effect. From 1990 to 2016, the average rainfall was 611.96 mm, the runoff was 225.96 mm, the surface runoff was 126.07 mm, the base flow was 72.07 mm, and the phreatic water recharge was 119.52 mm in the watershed. For the runoff, surface runoff accounts for 55%, base flow accounts for 27%, and subsurface runoff accounts for 18%. For the phreatic water recharge, the surface water contributes only about 5%, and the main recharge source is precipitation. Under the combined influence of climatic conditions and surface vegetation cover conditions, surface runoff decreased by 22% around 2006, the conversion of surface water to groundwater decreased, and the conversion of groundwater to surface water increased. The research results can provide theoretical basis and technical support for the rational development and utilization of water resources and the control of soil erosion in the Yimeng Mountain Area.
