摘要(Abstract)：

为了实现科尔沁沙地的水资源监测,该文采用2003年7月至2010年12月的GRACE月重力场模型,经过去相关滤波、高斯平滑滤波和GIA改正,利用尺度因子法恢复重力场信号,反演科尔沁沙地的陆地水储量变化,与CPC水文模型反演结果进行对比分析。研究结果表明:由GRACE Release-05Level-2数据反演得到的2003年7月至2010年12月科尔沁沙地陆地水储量下降速率为-13.2±2.6(mm·a-1);CPC水文模型反演的该地区陆地水储量变化曲线与GRACE反演结果呈现出良好的一致性,具有相似的季节变化;2009年秋至2010年春该地区陆地水储量呈现直线减少,并达到最低点,这一现象与该时段中国北方的干旱事件相一致。
