摘要：

利用2003-01～2016-06共162个月GLDASNOAHM.2.1、GLDASNOAHM.001新旧水文模型和GRACE卫星重力数据,计算青藏高原区域水储量及总质量变化,说明GLDASNOAHM.2.1水文模型相对于旧模型可提升在青藏高原区域的精度。将研究区域分为6个部分,根据3种数据分别计算6个区域的平均质量变化时间序列,顾及年周期、半年周期对该时间序列进行最小二乘拟合,估计6个区域3种数据的年振幅、年相位及相关性。结果表明,GLDASNOAHM.2.1水储量变化的年振幅、年相位与GRACE总质量变化的年振幅、年相位空间分布大体一致,在青藏高原北部区域与GRACE的相关性尤为明显;GLDASNOAHM.001年振幅、年相位在青藏高原北部区域存在明显异常,与GRACE的相关性很低。从长趋势质量变化来看,GLDAS新、旧模型在不同区域的差异为-6.4～4.5Gt/a量级,而在青藏高原主体区域,新模型的质量趋势偏低10.4Gt/a。
