| 摘 要： | 分析了新疆地区1998～2002年重力变化，研究了重力变化与伽师6．8级地震活动的关系，认为：重力场动态图像对伽师6．8级地震有较好的反映，重力测量可以较好地反映活动断层的物质迁移和构造形变引起的地表重力变化。 |
| 关 键 词： | 重力 地震 构造活动 重力场 重力剖面 新疆地区 伽师地震 |

| Abstract: | By systematically analyzing the gravity variation in Xinjiang area from 1998 to 2002, the relationship between Jiashi \%M\%s6.8 earthquake and the gravity variation is studied.It is considered that the gravity change is closely related to the tectonic activity and the earth's surface gravity variation may be caused by material migration accompanying active fault and crustal tectonic activity.The dynamic patterns of gravity field clearly mirror the seismogenic process of Jiashi Ms6.8 earthquake. |
| Keywords: | gravity variation tectonic activity Jiashi earthquake |
