摘　　要：我国干旱灾害发生频繁,造成的损失严重。传统的干旱监测主要基于气象和水文数据,在监测面上的旱情时存在局限。基于新质生产力开展旱情监测迫在眉睫,也是新时期干旱灾害防御工作的重要着力点。近年来,随着卫星遥感技术快速发展,大范围、高精度、高频次、全天候对地观测能力基本形成,旱情遥感监测由早期的模型研究向业务化应用方向发展,多源遥感星地协同旱情监测、精细化旱情综合评估以及遥感、水文气象耦合的旱情预警是未来发展趋势。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.
