摘要
本文介绍了第七代国际地磁参考场（IGRF）．利用IGRF1995计算并绘制1995．0年中国及邻区地磁图．考虑了地球扁率对计算结果的影响．
In this paper, the seventh generation IGRF was introduced.Based on the IGRF1995, the grid values were calculated, the geomagnetic charts were drawn for the everygeomagnetic component(D, I, H, F, X, Y, Z) over China and adjacent areas at epoch1995.0. The ellipticity of the Earth was accounted, the effect of ellipticity was computedand analysed.
