摘要
着重介绍了北京顺义4．0级地震前后板桥井水位的异常特征，并通过对板桥井二次异常的对比分析研究，提出井水位异常时间尺度与震级之间的可能关系。
This paper mainly introduced the anomalous feature of the ground water behaviour in Banqiao well around the Shunyi earthquake with M 4. 0,Beijing. It put forward apossible relation between the time range of water level anomaly and the earthquake magnitude through the contrast analysis of the secondary anpmaly.
