为纪念“3912”建队三十周年,本文回顾了1950~2000年中国地磁测量和地磁图,回顾了“3912”任务的光辉业绩,阐述了“3912”
The geomagnetic surveys and geomagnetic charts in China at epoch 1950,1960,1970,1980,1990 and 2000 were reviewed. The geomagnetic survey was carried out in the Qinghai-Xizang plateau and Julmolunhma Mount region from 1964 to 1966. The extensive geomagnetic survey was carried out in China from 1969 to 1972. The models of main field and secular variation in China were derived by using Taylor polynomial in latitude and longitude for 1950~2000. Some results of geomagnetic study in China for 1950~2000 were introduced. The truncation index,the boundary effect and the relationship between observed point density and geomagnetic model were analysed and discussed. The calculation methods of the geomagnetic model were reviewed. Some applications of the Chinese geomagnetic charts and models were given.
