中文摘要	针对黄河流域干旱、水资源短缺,陆地水储量较难监测的问题,本文利用GRACE重力卫星和GLDAS水文模型,分析了黄河流域陆地水储量的空间和季节变化特征;通过M-K趋势分析、滞后性分析及快速傅里叶变换等,探讨黄河流域水储量变化与降水、径流、气温等影响因子间的响应关系。结果表明: GRACE时变重力场能较精确反演黄河流域水储量变化;黄河流域陆地水储量整体呈现下降趋势,陆地水储量变化受同期径流的影响最直接;陆地水储量变化对降水、气温及径流等主要水文气象因素的响应存在一定滞后性;对各影响要素作滞后相关分析,影响陆地水储量变化的主要水文气象因素是降水和气温,径流影响程度较低。
英文摘要	The Yellow River basin is an arid area suffering from a shortage of water resources,and it is hard to monitor the terrestrial water storage of the basin. This study analyzes the spatial and seasonal change characteristics of terrestrial water storage anomaly (TWSA) in the Yellow River basin based on the gravity recovery and climate experiment (GRACE) data and global land data assimilation system (GLDAS) hydrological model data. The response relationships between TWSA and its several influencing factors,including precipitation,runoff,and temperature,were studied through Mann-Kendall trend analysis,hysteresis analysis,and fast Fourier transform method. The results show that the GRACE time-varying gravitational field can accurately reverse the change of water reserves in the Yellow River basin. The TWS data presents an overall downward trend,and the TWSA is most directly influenced by runoff of the same period. There is a time lag in the response of TWSA to the main hydrological and meteorological factors,including precipitation,temperature,and runoff. After the lag correlation analysis of the main influencing factors,precipitation and temperature were derived as the main factors influencing TWSA, while runoff was found to have a low correlation.
