【摘要】：GRACE(Gravity Recovery And Climate Experiment)重力測(cè)量衛(wèi)星自2002年3月發(fā)射以來(lái),已經(jīng)提供了地球重力場(chǎng)十多年的觀測(cè)資料,該衛(wèi)星通過(guò)測(cè)量全球不同地區(qū)因質(zhì)量異常所引起的重力起伏來(lái)獲取陸地水儲(chǔ)量變化的總體分布信息,為監(jiān)測(cè)表層或深層水儲(chǔ)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(jìn)行水儲(chǔ)量變化研究的國(guó)內(nèi)進(jìn)展,重點(diǎn)介紹了GRACE重力衛(wèi)星及其在國(guó)內(nèi)湖泊流域、河流流域和高原冰川等區(qū)域水儲(chǔ)量變化反演的研究,并從氣候因子和人口社會(huì)經(jīng)濟(jì)因子分析了我國(guó)水儲(chǔ)量變化的特點(diǎn),同時(shí)還探討了GRACE在研究我國(guó)水資源儲(chǔ)量中的技術(shù)瓶頸、可能的解決方案和未來(lái)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.
