摘　　要：近年来,极端天气事件呈现趋多、趋频、趋强、趋广态势,干旱灾害的极端性、反常性越来越明显,干旱灾害风险的复杂性、多变性也愈来愈显著。2022年,水资源相对丰沛的长江流域发生1961年有完整记录以来最严重的气象水文干旱,影响波及流域农业生产、城乡供水、生态、航运、发电等诸多方面。在总结2022年长江流域旱情、旱灾特点的基础上,分析长江流域抗旱减灾工作中存在的难点及问题,并有针对性地提出了未来抗旱减灾工作重点的建议。In recent years, extreme weather events have become more frequent, stronger and wider. The extreme and abnormal nature of drought disasters are becoming more and more obvious, and the complexity and variability of drought disaster risks are becoming more and more prominent. In 2022, the Yangtze River Basin with relatively abundant water resources experienced the most severe meteorological and hydrological drought since records began in 1961,causing severe difficulties in agricultural production, urban and rural water supply, ecology, shipping, power generation and other aspects of the river basin. Based on the analysis of the characteristics of drought in the Yangtze River Basin in2022, this paper puts forward some thoughts on the difficulties and problems existing in drought disaster reduction in the Yangtze River Basin, and some suggestions on the focus of future drought disaster reduction.
