摘　　要：文章收集了河南中、北部地区的测井大地热流数据、地温梯度 ,并由大地电磁测深 ( MT)成果中所得到的壳内高导层埋深 ,利用 A· A′da′m给出的经验公式 :HFCl=35Q- 1.3换算出部分地区的大地热流数值。文章通过对上述地热场资料的综合分析研究得到研究区地热场在横向和纵向上的非均匀特征 ,进而初步推断出研究区深部可能存在的地热应力区 ;同时 ,文中对该地区的地热场特征与其地质构造背景以及深部环境的关系也做了初步分析研究。The logging geothermal flux data and geothermal gradient data in the middle north region of Henan Province are collected and analyzed in this paper.Also geothermal flux data of sectional site in this region are transformed from depth of high conductive layer in the earth's crust from magnetotelluric sounding method making use of experience formula H fcl =35Q -1.3 given by A·A'da'm.Inhomogenous character in vertical and horizontal directions of geothermal field within studied area are obtained by comprehensive analysis and study of the geothermal field data mentioned above.It is inferred preliminarily that there may exist a geothermal stress region in the deep layer within the studied area.In addition,the relationship between geothermal field character and its geological structure background and deep environment in the area are analyzed and studied preliminarily in this paper.
