摘　　要：2018年2月4日至2月21日阳西台水位出现短期异常,通过数据变化特征的分析、野外调查、抽水实验、数据比对观测分析,排除仪器故障、降雨干扰,汽车站水井抽水等干扰因素,认为此次异常与阳西新湖震群活动、阳西3.7级地震相关。From February 4 thto February 21 st, 2018, there was a short-term groundwater level anomaly at Yangxi Station. By the analysis of data variation characteristics, field investigation, pumping experiment and data comparative observation, the interference factors such as instrument failure, rainfall interference and water well pumping at bus station are eliminated. It is considered that the anomaly is related to the activity of Yangxi Xinhu earthquake swarm and Yangxi M3.7 earthquake.
