永定河流域水资源是支撑区域节水和生态建设的重要基础条件之一。然而，由于观测数据非常有限，水资源在最近人类活动下的历史变化仍然未知。在这项研究中，陆地水储存异常（TWSA）以及多次降水和实际蒸散产品的卫星收集，并通过观测数据或成对比较验证数据的准确性。利用水量平衡法重建了1980-2016年北京平原地下水动态平衡，并利用GRACE观测的北京平原地下水动态平衡、历史文献记载的北京平原地下水平均埋深和官厅水库实测径流对重建后的北京平原地下水动态平衡进行了验证。重建的TWSA数据表明，2000-2016年期间出现了显著下降，平均下降趋势率为-11 mm/年，这可能是由于农业发展导致地下水储量减少所致。然而，重建的TWSA在1980-1999年期间略有下降。建立的水资源储备赤字指数（WSDI）表明，1980-1999年没有干旱或轻度干旱，但2000-2016年由于农业发展导致地下水储备减少，水资源短缺更为严重。WSDI的验证使用常用的自校准帕尔默干旱严重程度指数。研究结果对黄河下游水资源可持续管理具有重要的参考价值。
Water resources in the Yongding River basin (YRB) are one of the important fundamental conditions in supporting regional water conservation and ecological development. However, the historical changes in water resources under recent human activities remain unknown due to very limited observation data. In this study, terrestrial water storage anomalies (TWSA) as well as multiple precipitation and actual evapotranspiration products from satellites were collected, and the accuracy of the data was verified by observed data or pairwise comparisons. The TWSA during 1980-2016 was reconstructed by using the water balance method, and the reconstructed TWSA was verified using GRACE-observed TWSA, the average depth to groundwater in the Beijing Plain from historical document records and the observed runoff from Guanting Reservoir. The reconstructed TWSA data indicated that the significant decrease occurred during 2000–2016 and the average rate of decreasing trend was -11 mm/year, which may have been caused by a decrease in groundwater storage due to agricultural development. However, the reconstructed TWSA decreased slightly during 1980-1999. The establishment of the water storage deficit index (WSDI) showed that there was no drought or mild drought during 1980-1999; however, the water resource shortage during 2000-2016 was more serious due to groundwater storage decreases caused by agricultural development. The WSDI was verified by using the commonly used self-calibrated Palmer drought severity index. The findings are valuable for sustainable water resource management in the YRB.
