| 摘 要： | GRACE卫星成功开辟了空间大地测量对地观测的新途径.利用GRACE卫星得到的时变地球重力资料,分析估计了中国及其周边地区陆地水量的变化趋势,较为清晰地揭示了该地区季节性变化特征.进一步采用13点滑动平均的方法扣除了季节性变化,提取了4个特征区域(喜马拉雅南部,新疆与西藏及其周边的亚洲高山区域,中国华北、东北地区和中国...

| Abstract: | The success of GRACE has blazed a new trail in the Earth observation on space geodesy.Based on the time-varying gravity anomaly data of the GRACE mission,long-term variations of continental water storage in China and its adjacent areas were estimated.Seasonal changes of water storage in China and its adjacent regions have been clearly revealed.With the remove of seasonal changes by 13-points moving averages,the long-term change rates of continental water storage in four distinct zones,namely southern Himala... |
