摘　　要：本文对福建地区的航磁资料进行了不同高度的延拓处理,并给出了福建地区的居里等温面的计算结果。在此基础上,对福建地区的居里等温面及其与地震的关系作了初步探讨。Based on the extension treatment of aeromagnetic data at different altitudes, this paper presents the calculation results of surface isothermal curie temperature and discusses its relation to earthquake in Fujian. The results are as follows:1. The surface isothermal curie ranges between 17 km and 22 km, and runs generally in the NE and NW strikes which coincides, on the whole with the geologic structure line in Fujian.2. The correlation of the depth distribution of surface isothermal curie and the crustal thickness distribution indicates their general simility in the trend of change, namely the trend of gradual decrease from the west to the east.3. The relation of isothermal surface of curie and earthquake in this area is studied. It is found that the stress due to the difference of the temperature between two adjacent regions is very important for earthquake occurrence.
