摘　　要：干旱是当今世界出现频率最高、持续时间最长、危害范围最广的重大气象灾害,对全球农业、生态、社会发展和国民经济等影响巨大而广泛。农业旱灾是影响农业生产的重要因素,农业生产关乎着国家粮食安全。我国是一个农业大国,同时也是一个旱灾频发的国家,深入了解农业干旱灾害的成因、影响特征、旱灾强度、严重程度以及作物致灾的生理过程和机理等是提升农业干旱灾害监测预测预警水平、减轻和防御灾害损失、提高国家粮食安全生产需要解决的重要科学问题。本文综合回顾了国内外不同程度的农业干旱及其对粮食生产影响的最新研究进展,从农作物形态、生理、细胞和分子水平等方面探究了干旱影响特征及机制,围绕粮食生产如何有效应对农业干旱问题,评述了当前农业干旱监测的主要指标、方法、预警系统等,针对农业可持续发展和干旱新特征,讨论了当前防旱减灾和农业干旱应对的现状,强调了适应与减缓并举的一系列干旱应对措施,在此基础上结合国家、区域和行业发展需求提出了今后应着重加强的重要科学问题、研究对策及学科发展展望。Drought is a major meteorological disaster with the highest frequency,the longest duration and the widest scope of harm in the world today,which has a huge and extensive impact on agriculture,ecology,social development and national economy all over the world.The drought is an important factor affecting agricultural production which determines the stability of crop production,further re⁃lates to the national food security.China is a large agricultural country,and also is a country with frequent drought disaster.Therefore,to improve the monitoring,forecasting and warning level of agricultural drought disaster,it is necessary to deeply understand its forma⁃tion,influence characteristics,drought intensity,severity and physiological process and mechanism of crop victimization.It is also an important scientific problem to reduce and prevent drought disaster losses and improve national food security production.This paper comprehensively reviews the recent internal and overseas research progress of agricultural drought with different degrees and its impact on crop production,and explores the influence characteristics and mechanism of drought from the aspects of crop morphology,physiol⁃ogy,cellular and molecular levels,etc.The main indicators,indexes,methods and early warning systems in current agricultural drought monitoring are reviewed around food production to cope effectively agriculture drought.According to the new characteristics of agricul⁃tural sustainable development and drought,the current situation of drought disaster prevention and mitigation and agricultural drought coping are discussed.A series of drought coping measures both adaptation and mitigation are emphasized.On this basis,combining with the needs of national,regional and industrial development,the paper puts forward the important scientific problems,research coun⁃termeasures and the prospect of discipline development which should be emphasized in the future.
