Abstract: The Daqinghe River basin is the most prominent area of groundwater overdraft in the Haihe River basin.In order to solve the problem of groundwater overdraft, this study carried out the suitability evaluation of integrated groundwater recharge in mountainous and plain areas in the basin.Select the buried depth of groundwater level, permeability coefficient, distance from the main canal of the middle line of the South-to-North Water Transfer, distance from the reservoir, precipitation infiltration coefficient, effective water storage space, slope, and surface elevation to build the GIS-AHP decision model to obtain the zoning map of the suitability of the study area, and use numerical simulation to evaluate the effect of the replenishment.The study shows that the suitable areas for recharge are mainly distributed in the piedmont reaches of Juma River, Qinglong River, Tanghe River and Cihe River, accounting for 4.5% of the total assessed area; at the same time, according to the assessment results of the suitability of recharge, the refined water replenishment scheme for river sections can greatly slow down the decline rate of groundwater storage variables, and the recharge is the best.Therefore, the suitable assessment of groundwater recharge in the basin based on the combination of GIS and numerical simulation is helpful to greatly improve the utilization efficiency of water resources in the region and provide the optimal over-extraction control scheme.
