This research aims to analyze the influencing factors of aquifer recharge management in the Sanjiang Plain, China, by utilizing Geographic Information System(GIS)and Analytic Hierarchy Process(AHP)to construct a suitability evaluation system for Agricultural Managed Aquifer Recharge(Ag-MAR). The results indicate that areas with deeper groundwater levels are more suitable for recharge, accounting for approximately 20.2% of the total study area, while the region's dense river network provides substantial surface water resources. Additionally, the optimal recharge period is identified as spanning from mid-October to early November. This study provides a scientific basis for groundwater management and presents specific recharge recommendations to address the issue of groundwater over-extraction, thereby ensuring the sustainability of both agricultural production and ecological systems. The findings underscore the importance of Ag-MAR in promoting sustainable groundwater management practices in agricultural regions.
