摘　　要：2013年5月7日～9日河南濮阳清丰地震台清丰2号井水位快速下降约0.18m,下降幅度大于平常下降幅度,9日起水位慢慢恢复.对产生水位快速下降的原因进行了调查分析,研究结果显示：河南濮阳清丰2号井水位下降是由于同层地下水开采抽水造成的,不是地震前兆异常变化.In May 7th to 9th, 2013, the water level of No. 2 well in Qingfeng seismic station was dropped rapidlyabout 0.18 meters, the dropped amplitude was more than that of usual, then the water level started to recoverslowly. The causes of waler level dropped fast are analyzed, the results show that the cause is the same layerwater pumping of nearby the well, it is not earthquake precursory anomaly.
