摘要
利用1984—2012年琼中、邕宁地磁台近30年的观测资料,通过年均值的年变化和年变率来分析两台的地磁场长期变化规律和特征,为了解本区域地磁场的长期变化提供一定参考。
By using observation data of Qiongzhong and Yongning station for nearly 30 years from 1984 to 2012.The paper analyzes the long-term variation and characteristics of the geomagnetic field of these two stations by using the annual variation and annual variation rate, which can provide a certain reference for understand the geomagnetic field changes of this region.
