英文摘要An natural orthogonal component model of secular variation of the geomagnetic field in China was established for the period of 1985-1997 by means of natural orthogonal component methods (NOC's) on the basis of the data of 20 geomagnetic observatories in China and 3 geomagnetic observatories in Japan. The root mean square (RMS) of geomagnetic field components of 23 observatories were calculated for NOC truncation levels 1-9, the contour maps of orthogonal model values for k(NOC) = 1-3 were constructed for 1995 epoch. The results show that the contours of secular variation of X, Y and Z components are very smooth and uniform in distribution and have obvious regional feature. In some areas, the secular variations are very large, reflecting local feature of geomagnetic field and the related geophysics phenomena.
