摘要
根据青藏高原地磁三分量绝对测量资料，使用泰勒多项式方法和冠谐分析方法，计 算了青藏高原地磁场（Ｘ， Ｙ，Ｚ ）的泰勒多项式模型和青藏高原地磁剩余场（△Ｘ，△Ｙ，△Ｚ）的冠谐 模型，并绘制了相应的理论地磁图．分析了磁异常点对地磁场模型的影响，对比分析了地磁 场的多项式模型和冠谐模型，讨论了地磁场模型的边界效应问题．
Based on the geomagnetic three-components absolute survey dare and by use of the Taylor polynomial method and foe spherical cap harmonic analysis method, the Taylor polynomial models of the geomagnetic field (X Y and Z) and the spherical cap harmonic models of the geomagnetic residual field (△X △Y and △Z over Qinghai-Xizang plateau are calculated, and corresponding theoretical geomagnetic charts are constructed, too. The effects of geomagnetic anomalous points on the geomagnetic field model are analysed, a comparison between the polynomial model and the spherical cap harmonic model of the geomagnetic field is carried out and the boundary effects of the geomagnetic field model are discussed, too.
