| 摘 要： | 通过对北祁连～河西地区重力变化的分析，认为重力变化由缓慢下降发展为快速下降，并形成重力变化高梯度带，同时大面积地形变和断层水准变化显示为由急剧上升转变为缓慢下降，表明该地区已进入应力积累的中期阶段，应密切监视其发展变化

| Abstract: | By analyzing the gravity change in the northern Qilian~Hexi region,it is considered that the gravity change drops from slow to quick and forms a high gradient zone.The wide-ranging crustal deformation and cross-fault deformation have turned quick rise into slow drop,it has got into middle preparation period of strong earthquake.Therefore,it is carefully monitored. |

| Keywords: | Mobile gravity measurement Gravity contour Deformation Cross fault leveling North Qilian Hexi region |
