摘　　要：通过岩石圈厚度变化、大地热流值和莫霍面起伏,结合浅表岩浆构造活动,编制了华北地区深部构造略图,建立了燕山期软流圈上涌与岩浆构造活动的关系模式,总结了该区的深部构造特征:岩石圈厚区与软流圈上涌区共存。同时,按生成机制对该区软流圈上涌进行了类型划分:中生代燕山期(J—K1)、早新生代(E2—E3)主动机制形成的软流圈上涌,中、新生代(K2—E1)及晚新生代(N—Q)被动机制形成的软流圈上涌。Based on the great change of the lithosphere thickness, the geothermal flow and Moho surface, and epigenetic magma structure activities, the sketch map of deep-seated structure of North China is constituted, and the relationship model of Yanshanian upwelling of asthenosphere and lithosphere structural activity is built. Also the deep-seated structure is characterized by the co-existence of the thick area of lithosphere and the upwelling of asthenosphere. At the same time, the upwelling of asthenosphere in this area is divided according to the mechanism. It is found that the upwelling of asthenosphere in Mesozoic Yanshanian （J-K1）, Early Cenozoic（E2-E3 ） is active mechanism, and the upwelling of asthenosphere in Mesozoic, Cenozoic（K2-E）, Irate Cenozoic （N-Q） is passive mechanism.
