| Abstract: | In order to optimize the condition of the geomagnetic observation, the moving work of the Yanjiao and Xiadian sites was carried out. According to the principle and technical program of moving the site, the basic geological and geophysical data and others were collected and sorted out completely. The field investigations and measurement of geomagnetic gradient were performed, and new sites were determined. The geomagnetic field was comparatively observed at the new and old sites for long time. Using the many methods, the geomagnetic data of the comparative observation were analyzed and researched. The results show that the geomagnetic variations at the new, old and relative sites have good consistent. The site differences of geomagnetic data between the new and old sites were also obtained . |
