摘　　要：以三江平原为典型研究区,分析农业灌区含水层补给的优势及影响因素,选择地下水位埋藏深度、人工补给水源、包气带岩性、含水层特征、地形坡度、土地利用和土地覆盖作为主要影响要素,利用地理信息系统(GIS)和层次分析法(AHP)构建农业可管理的含水层补给(Ag-MAR)适宜评价体系.结果表明,三江平原适宜开展含水层补给的区域主要集中在东北部地下水位埋深较大的地区,而该地区密集的河网提供了充足的地表水资源.研究区的集中补给时间为10月中旬至11月初.该研究为地下水管理提供了科学依据,并提出了具体的补给建议,以解决地下水超采问题,确保农业生产和生态环境的可持续性.研究结果强调了Ag-MAR在促进农业地区可持续地下水管理实践方面的重要性,这一方法不仅适用于三江平原,也可推广至其他类似的农业灌区,丰富了水资源管理领域的理论研究.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.
