摘要

    

In this paper,  the variation characteristics of mobile gravity and geomagnetic data in the western Shandong Province and adjacent areas is systematically analyzed from the temporal and spatial point of view combining with seismic activity. Particularly, the change characteristics of the geomagnetic data observed since 2001 in the area is described in detail and compared with gravity data in the juncture area of Hebei, Shandong, Henan provinces. The analysis indicates that gravity and geomagnetic field in this area show significant gradual characteristic, which may reflect the different embryonic stage of earthquake.
