摘　　要：盆岭构造研究始于20世纪70年代。21世纪以来,将"盆岭构造"研究纳入了"板块构造"的范畴。根据盆岭构造形成机制,认为苏鲁造山带、宁镇剪切拉分带及苏锡旋圈构造群是江苏3个典型的盆岭构造。此外,在徐州、苏北盆地、宁芜、茅山、宜溧、昆山等地"盆岭"相伴出现,如徐州地区反射弧两侧潘塘盆地和宋楼—马坡盆地、苏北盆地的建湖隆起与高邮坳陷、茅山地区的茅山山脉与直溪桥凹陷、宜溧山区与火山岩盆地等,都是伸展构造发育的盆岭构造带。这些地区以伸展构造为主体,推覆构造十分发育。The research on basin and range tectonics began in the 1970 s,and it was incorporated into‘plate tectonic category’since the 21 st century. According to the formation mechanism of basin and range tectonics,the authors suggested that there were three typical basin and range tectonics,namely,Jiangsu-Shandong（ Su-Lu） orogenic belt,Nanjing-Zhenjiang（ Ning-Zhen） shear and pull-apart belt and Suzhou-Wuxi（ Su-Xi） vortex tectonic group distributed in Jiangsu Province. Besides,the basin and range tectonics were accompanied in Xuzhou,North Jiangsu Basin,Nangjing-Wuhu,Maoshan mountains,Yixing-Liyang,Kunshan etc. For instance,the Pantang basin on two flanks of reflex arc in Xuzhou area,Songlou-Mapo basin,Jianhu uplift of basin and Gaoyou depression in North Jiangsu Basin,Maoshan mountains and Zhixiqiao depression in Maoshan area,Yixing-Liyang mountainous areas and volcanic rock basins etc,were all stretching tectonics developed well in basin and range tectonics belt. On the basis of stretching tectonics,these areas were of favorable development of nappe structure.
