| 摘 要： | 本对云南内昆明，弥渡，下关等重力台站的重力固体潮观测资料进行了系统的研究。阐述了重力异常的提取判据，统计下重力异常与５级以上地震的历史对应情况，总结了重力异常变化特征，给出了重力异常短临指标体系，从而为今后的地震预报在重力学科提供了一些异常指标的定量依据。

| Abstract: | Systematic research on the observation data of gravity earth tide at the gravity stations of Kunming, Midu and Xiaguang in Yunnan Province is made, including extracting criterion of gravity anomaly, counting historical correspondence between earthquakes with over M 5 and gravity anomaly, summing up variation characteristics of gravity anomaly and offering short-impending index system for gravity anomaly, which provides some quantitative basis of gravity anomaly index for future earthquake prediction. |
