摘　　要：以通海地磁台2006—2015年地磁观测资料为研究对象,分析通海台地磁场长期变化及地磁场各分量变化规律;研究台站年均值与IGRF模型计算值的一致程度,计算了异常场模量.结果表明,通海地磁台实测值在2011年及2014—2015年变化较快,总体来说2008—2015年期间通海台地磁记录资料可靠性高,与模型值同步变化程度高,磁场变化与模型值变化趋势基本吻合.Based on geomagnetic observation data during 2006--2015 in Tonghai, the analysis of the geo- magnetic environmental field and each variation of the geomagnetic field components have been done. We have some research on consistent level as to the annual average level at the stations and IGRF model calculated values, and we also have calculated anomalous filed modulus. The results show that the sea geomagnetic values in 2011,2014 and 2015 vary rapidly.Studies show that during 2006 to 2015 sea tableland magnetic data is of high reliability, and of a high degree of variation with synchronization model values.In addition geomagnetic measured value and model value change trends coincide.
