GRACE卫星数据在国内陆地水储量反演中的应用综述

Review on the Application of GRACE Satellite in China's Terrestrial Water Storage

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。

Since the launch of the GRACE（Gravity Recovery And Climate Experiment） gravity measurement satellites in March 2002,it has provided more than 10 years of observation data of the earth＇s gravity field. The overall distribution of water resources will be obtained by measuring the fluctuation of gravity caused by water resources in different regions of the earth,which provides a new method for monitoring the surface layer or deep layer water reserves. This paper systematically reviews the research progress of GRACE satellite data for domestic water resources reserves. The GRACE gravity satellite and its exploration in the domestic lake basin,river basin and plateau glacier are mainly introduced. And analyzing the characteristics of water reserves in China from the climatic factors and socio-economic factors,and also discusses the technical bottlenecks,possible solutions and future prospects of GRACE in the study of China＇s water resources reserves.
