摘　　要：采用2014—2015年福建地区流动地磁观测资料分析福建区域岩石圈磁场变化情况,利用向上延拓处理方法对福建地区岩石圈磁场变化信息进行了局部与区域异常场分离,结果表明在漳州南部地区磁异常变化比较明显。基于区域异常场分离结果,反演居里等温面深度,初步得到福建地区居里面埋深大约为16~28 km。Using the geomagnetic data recorded by mobile geomagnetic measuring in the Fujian area during 2014 and 2015, we obtained the variations of the lithosphere magnetic field. Upward continuation has been used as a meth- od to separate the local and regional anomaly field. The results show that there were obvious geomagnetic anoma- lies in southern Zhangzhou. Based on the results of regional anomaly field, the Curie isothermal depth inversion was carried out. The results show that the Curie isothermal depth is approximately 16 -28 km in Fujian.
