摘　　要：依据内蒙古全区的地层资料，采用板块构造观点，依据建造类型、生物群特征、构造环境对内蒙古大地构造进行了分区。共划分了华北板块、西伯利亚板块、塔里木板块三个一级构造单元。华北地块、华北北部大陆边缘、华北西部大陆边缘、塔里木北东大陆边缘和西伯利亚东南大陆边缘五个二级构造单元。并进一步划分了火山型和非火山型被动陆缘等十个三级构造单元。对各单元特征进行了较为系统的介绍和论述，特别是融入了大量新的１／５万区调成果资料，在诸多方面有了新的认识。?According to stratigraphic datum of Inner Mongolia area,tectonic has been divided into various areas based on research viewpoint of plate tectonics,such as formation type,biological group of character and tectonic setting.Three of primary tectonic units have been divided into North China,Siberia and Tarim plates,and five of second units are North block,the northem and the westem part of North China,the north-east of Tarim and the east-south of Siberia continental margin.Ten of third tectonic have been divided into volcanic and nonvolcanic types of passive continental margin.Systematic introduction and discussions had been made to each unit’s character.Especially a vast amount of new 1:50000 regional geological surveying data has been added so that new recognition had been made in many aspect.
