| 摘 要： | 通过对顺义地震的序列特征、地震活动与加卸载响应比等前兆异常的时空演化等方面的研究，认为顺义的地震为一次非前光性震群；震前存在地震条带、３级以上地震东移、南北向小震条带、响应经异常地震活动异常以及以顺义板桥水位为主要的破年变等前光异常，这些前光异常的时空演化过程表现出与中强地震类似的具有一定力学基础的三阶段特征，这些结果对北京及邻区的中等以上地震的预测研究与短临跟踪工作都具有重要参考作用。

| Abstract: | In this paper,the sequence feature,earthquake activity,Spatial\|temporal evolution of the load/unload response ratio,etc.of the Shunyi earthquake have been studied.The results show that,the Shunyi earthquake is a non\|precursory swarm.There exist some seismic anomalies and precursors before the earthquake.For example,earthquake belt,migration toward the east of earthquakes with M \-S3.0,small quakes belt in north\|south direction,the load/unload response ratio anomaly,non\|annual variation of the Banqiao water level in Shunyi county and so on.The Spatial\|temporal evolution characters of these precursors are similar as three stages feature of certain mechanical basis before strong earthquakes.The results are important references for studying moderate shocks and tracing short\|term and imminent earthguake prediction in and near Beijing area. |
