摘　　要：系统总结了40多年来东北地区旱地农业研究取得的进展,分析了当前东北地区旱地农业面临的问题,揭示了影响东北地区旱地农业生产的气候变化、水分供需、农田侵蚀和面源污染规律,重新制定了东北地区耕作制度区划,突破了一系列旱地农业生产关键技术,形成了多套适合东北不同区域的旱地农业综合技术模式,明确提出了现阶段东北旱地农业所面临的挑战,并指出了未来东北旱地农业的发展对策。This paper comprehensively reviewed the research progress on dryland agriculture in northeastern China,analyzed the issues faced by the dryland agriculture in northeastern China and revealed the pattern of climate change,water supply and demand,farmland erosion and non-point source pollution affecting the dryland agriculture in northeastern China,therefore cropping system regionalization was redesigned,numbers of breakthroughs were made on key technical problemsin dryland agriculture producion,and several integrated technology modes for dryland agriculture in different part of northeastern China were formed.Challenges forthe current development of dryland agriculture in northeastern China were put forward and countermeasures were provided.
