摘　　要：干旱是全球范围内普遍存在的自然灾害,对环境、生态、经济和社会等多个方面产生深远影响。GRACE(Gravity Recovery and Climate Experiment)重力卫星通过测量地球重力场变化数据可动态监测陆地水储量变化。应用GRACE获得的水储量时空分布信息,可监测干旱,以研究干旱事件的发生、发展与演变过程。采用文献计量法分析总结了GRACE卫星数据在地下水储量变化、气象与水文干旱演变规律与响应、干旱预警等方面的应用现状及存在数据验证与数据插补重建方面的问题,并展望了变化环境下水储量变化、构建更适合干旱监测的干旱指数、提高GRACE数据精度、提升GRACE数据时空分辨率、干旱预警和决策支持以及区域水循环和生态系统响应等研究方向,可为后续的相关应用研究提供一定参考价值。Drought is a natural disaster that is prevalent on a global scale and has far-reaching impacts on many aspects,including the environment,ecology,economy,and society.Gravity recovery and climate experiment(GRACE)gravity satellites can dynamically monitor changes in terrestrial water storage by measuring data on changes in the Earth's gravity field.The spatial and temporal distribution information of water storage obtained by GRACE can be used to monitor droughts,so as to study the occurrence,development,and evolution of drought events.In this paper,the bibliometric method was used to summarize the current application of GRACE satellite data in groundwater storage changes,meteorological and hydrological drought evolution pattern and response,drought early warning,etc.,as well as problems in data validation,interpolation,and reconstruction.It also looked forward to the research directions of observing water storage change in changing environment,constructing a drought index more suitable for drought monitoring,improving the accuracy of GRACE data,and enhancing the temporal and spatial resolution of GRACE data,drought early warning,and decision-making support,as well as the response of the regional water cycle and ecosystems,which can provide a reference for the subsequent related application research.
