【摘要】：GRACE(Gravity Recovery And Climate Experiment)重力測量衛(wèi)星自2002年3月發(fā)射以來,已經(jīng)提供了地球重力場十多年的觀測資料,該衛(wèi)星通過測量全球不同地區(qū)因質(zhì)量異常所引起的重力起伏來獲取陸地水儲量變化的總體分布信息,為監(jiān)測表層或深層水儲量變化提供了新方法。系統(tǒng)綜述了利用GRACE衛(wèi)星重力數(shù)據(jù)進行水儲量變化研究的國內(nèi)進展,重點介紹了GRACE重力衛(wèi)星及其在國內(nèi)湖泊流域、河流流域和高原冰川等區(qū)域水儲量變化反演的研究,并從氣候因子和人口社會經(jīng)濟因子分析了我國水儲量變化的特點,同時還探討了GRACE在研究我國水資源儲量中的技術(shù)瓶頸、可能的解決方案和未來展望。
[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.
