摘　　要：通过对通海地磁台观测仪器和观测资料的评价,选用基线值、日均值和F差值为分析对象,将同一记录仪器由不同观测仪器组合而确定的基线值进行一致性分析,之后将不同记录仪器经同一绝对观测仪器的观测组合得到的基线值校正后日均值也进行一致性分析,发现新建房屋对地磁总场有一定程度的影响,认为新建房屋对GSM-19F与G856AX测量F值的差值变化有一定的相关性。In order to evaluate the changes of geomagnetic environment and accuracy of instruments in Tonghai Geomagnetic Station, we choose the baseline value, the daily average and the F difference as our main objects. First we use the consistency analysis to determine the consistency of baseline values by using different observation data recorded by same instrument. Then we use the combined observation data recorded by different instrument to adjust the baseline values. Our results show that the new houses affect the total geomagnetic field in some degree and F different values.
