基于多指标综合评价方法的河北省地下水储量现状风险分析OA

To systematically evaluate the current status and changing trend of groundwater storage in Hebei Province,this study integrates GRACE-DA remote-sensing data with GLDAS land-surface simulation data to calculate groundwater storage from 2003 to 2024,and constructs a three-level evaluation system based on the AHP-composite index method.The results show that groundwater storage in Hebei Province has exhibited an overall declining trend,with significant regional differences and particularly prominent overexploitation in the northern plain area.Although there has been a slight recovery in recent years under policy intervention,the overall resource situation remains severe.The conclusions can provide technical support and decision-making reference for regional water resources management and the sustainable utilization of groundwater.
