| 摘 要： | 在2015—2020年部分时段内，洛阳地震台水氡测值出现异常变化，利用水质和地球化学分析方法，对观测井、周边水井、伊河、龙门煤矿进行分析，认为水氡异常变化主要与台站更换水泵、大气降水、伊河水位变化以及附近龙门煤矿透水有关，排除地震异常，可为周边地区震情研判提供参考。

| Abstract: | To study the anomalies of the water radon observations of the Luoyang well from 2015 to 2020, we did m-situ examinations several times, made a lot of investigations, and carried out experiments. To determine the cause of the anomaly, the source and exploiting interference are analyzed combined with geochemistry and water quality analysis. The Luoyang well, the well nearby the station, the Yihe river, and the Longmen mine are studied. The results showed that the replacement of pump, the change of water level of Yihe river, rainfall, and water burst of Longmen mine are major factors for the abnormal change of water radon. The anomaly variation of the water radon was not the precursor anomaly of earthquakes, which could provide a reference and judgement for earthquake prediction. |
