摘　　要：在梳理长江流域干旱相关研究成果的基础上,从气象干旱、水文干旱、农业干旱3个角度评述了当前长江流域干旱评估指标的研究现状,阐述了长江流域干旱的时空特征及成因。指出当前研究在区域干旱的精准识别和多因素交互作用方面仍面临严峻挑战,未来长江流域干旱的主要研究方向包括提高多源数据综合利用水平,增强干旱监测的时效性与准确性;完善干旱监测及预报体系,提高干旱预测的科学性与可靠性;深化人类活动对干旱的响应研究,揭示人类活动与自然因素在干旱事件中的相互作用机制。Based on the research results on drought in the Yangtze River Basin,the current research status of drought assessment indicators in the Yangtze River Basin was reviewed from perspectives of meteorological drought,hydrological drought,and agricultural drought,and the spatio-temporal characteristics and causes of drought in the Yangtze River Basin were described.It was pointed out that the current research still faced serious challenges in the accurate identification of regional drought and the interaction of multiple factors.The main directions of drought research in the Yangtze River Basin in the future are put forward,including to improve the comprehensive utilization level of multi-source data and enhance the timeliness and accuracy of drought monitoring,to improve the system of drought monitoring and forecasting and enhance the scientificity and reliability of drought prediction,and to deepen the research on the response of human activities to drought and reveal the interaction mechanism between human activities and natural factors in drought events.
