摘　　要：东亚副热带夏季风北边缘带作为季风区和非季风区的过渡带,对我国西北地区东部、华北和东北地区,特别是黄河流域的天气、气候变化和极端灾害性天气气候事件的发生具有重要影响。本文回顾了有关中国夏季风北边缘带的定义、边缘带的空间界定和变化特征以及边缘带内气候变化趋势等不同角度的主要研究进展,并总结了影响夏季风北边缘带变化的可能因子。东亚副热带夏季风北边缘带是位于东亚大陆性气候系统与海洋性气候系统的交界区,在现代气候上表现为东北—西南向的半干旱、半湿润气候区。边缘带内气候变化复杂、自然灾害多以及影响因素多。最后提出了现有研究中关于夏季风北边缘时空分布精细化等方面的一些不足和值得进一步研究的问题。As the transition zone between monsoon and non-monsoon zones, the north boundary belt of East Asia Subtropical Summer Monsoon has significant influences on the weather, climate change and ex- tremely severe weather or climate events in the eastern part of Northwest China, North China and North- east China especially in Yellow River basin. The present work reviews the definition, characteristics, change trends of the north boundary belt of East Asia Subtropical Summer Monsoon and also summarizes some factors which may impact the boundary belt. The north boundary belt of the East Asia monsoon is in the juncture of continental climate and marine one in East Asia. This region can be divided into semi-humid and semi-arid subareas along the northeast-southwest direction, according to modern climate study. Cli- mate in this boundary belt is variable and is infuenced by multifactor, resulting in large amount of natural disasters. Due to the lack of the spatial and temporal distribution refinements on the northern edge of the summer monsoon, further worthy study is proposed in the last stage of this review.
