Abstract：Droughts occur frequently in China,causing severe damage.Traditional drought monitoring,primarily based on meteorological and hydrological data,has limitations in monitoring droughts on a regional scale.It is urgent to develop drought monitoring based on new quality productive forces,which is also a crucial focus for drought disaster prevention in the new era.In recent years,with the rapid development of satellite remote sensing technology,large-scale,high-precision,high-frequency,and all-weather earth observation capabilities have been established.Drought remote sensing monitoring has evolved from early model research to operational applications.The future trends include multi-source remote sensing satellite and ground collaborative drought monitoring,refined comprehensive drought assessment,and drought early warning systems that couple remote sensing with hydrometeorology.
