GRACE卫星数据在干旱研究中的应用综述
Overview of Application of GRACE Satellite Data in Drought Research
摘要
Abstract
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.关键词
