【摘要】：GRACE(Gravity Recovery And Climate Experiment)重力测量卫星自2002年3月发射以来,已经提供了地球重力场十多年的观测资料,该卫星通过测量全球不同地区因质量异常所引起的重力起伏来获取陆地水储量变化的总体分布信息,为监测表层或深层水储量变化提供了新方法。系统综述了利用GRACE卫星重力数据进行水储量变化研究的国内进展,重点介绍了GRACE重力卫星及其在国内湖泊流域、河流流域和高原冰川等区域水储量变化反演的研究,并从气候因子和人口社会经济因子分析了我国水储量变化的特点,同时还探讨了GRACE在研究我国水资源储量中的技术瓶颈、可能的解决方案和未来展望。
[Abstract]:Since its launch in March 2002, the GRACE(Gravity Recovery And Climate experimental satellite has provided observations of the Earth's gravity field for more than a decade.By measuring gravity fluctuations caused by mass anomalies in different regions of the world, the satellite acquires the general distribution information of land water reserves, which provides a new method for monitoring the changes of surface or deep water reserves.In this paper, the domestic progress in the study of water reserve variation using GRACE satellite gravity data is reviewed systematically. The research on GRACE gravity satellite and its inversion in lake basin, river basin and plateau glacier in China are emphatically introduced.The characteristics of water reserves in China are analyzed from climatic factors and demographic and socio-economic factors. The technical bottlenecks, possible solutions and future prospects of GRACE in the study of water resources reserves in China are also discussed.
