PRELIMINARY RESEARCH ON THE THREE-DIMENSIONAL MODEL OF GEOMAGNETIC FIELD IN CHINA AND ITS APPLICATIONS

In this paper,we successfully established the 3-D model of geomagnetic field in China(using temporal-spatial variable fitting method).This model overcame the incontinuity of the previous models and was easily applied.This model can preliminarily be used in geological structure,distribution of lithology,active block and earthguake trend of mid-long range.It showed a wide-ranging practical prospects on these aspects.
