%X 利用2014—2015年福建地区4期流动地磁观测资料，得到该地区岩石圈磁场特征信息。经过5 km、10 km、20 km、30 km等不同高度的向上延拓处理，对福建地区岩石圈磁场特征信息进行浅部与深部异常场分离，提取深部异常。结果发现在福建长乐—诏安断裂带出现比较明显的磁异常，即在该断裂带南部和中北部发现磁场正负高值的交替变化，这些磁异常与地质构造的分布、地震活动性有一定的关系。<br>In this study, we obtained information on the characteristics of the lithosphere magnetic field in the study area using four mobile geomagnetic observation datasets recorded in the Fujian region during 2014-2015. In order to separate shallow and deep anomalies, the data was processed with upward continuation, at depths of 5 km, 10 km, 20 km, and 30 km, among others, and the deep anomalies were extracted. The results show that there were obvious geomagnetic anomalies in the Changle-Zhaoan fault zone, which might be related to the geological structure distribution and the seismic activity in the Fujian region.
