Spherical harmonic analytical method is usually used to express the globaldistribution of the geomagnetic field (global model), and polynomial method isemployed to express the regional distribution of the geomagnetic field (regionalmodel). In this paper, on the basis of the regional models of the geomagneticfield in China at epoch 1980.0 (CGRF 1980) and the global models of the geo-magnetic field at epoch 1980.0 (DGRF 1980), the differences between CGRF1980 and DGRF 1980 were calculated (diff. =CGRF 1980-DGRF 1980), andcontour maps of the differences were constructed for total intensity (F), verti-cal intehsity (Z), horizontal intensity (H), declination (D) and inclination (I),with some analyses and discussions made. These maps show that the differencesbetween CGRF 1980 and DGRF 1980 are comparatively small in most parts ofChina, but obviously grow larger in border areas of Northwest and Northeast China.
