采用三维磁性层反演方法，研究了渤海及周边地区的居里等温面起伏。结合地表热流值、地壳厚度及地壳上地幔的电性结构，分析了研究区的深部地质特征。发现渤海及济阳坳陷北部的垦利至黄河口地区，居里面的深度只有１３～２０ｋｍ，而胶辽和承德地区却深达２２～２４ｋｍ。该项研究旨在对地震区划的深部构造背景问题提出新的建议。
Using the three-dimensional magnetic layer inversion method, the Curie isotherm fluctuation in the Bohai Sea and surrounding areas was studied. Combined with surface heat flow, crustal thickness and the electrical structure of the crust and upper mantle, the deep geological features of the study area are analyzed. The areas from Kenli to Huanghekou in the northern Bohai Sea and the Jiyang Depression were found to be 13 ~ 20km deep in the center and 22 ~ 24km deep in the Jiaoliao and Chengde areas. The study aims to put forward new suggestions on the deep tectonic setting of the seismic zoning.
