摘　　要：通过对辽宁盘锦地区盘一井水氡观测资料分析总结、归纳,综合阐述了盘一井水氡对辽宁及邻近地区历史5级以上地震的动态变化趋势特征。基于R值评分方法对映震效能进行检验,计算得到盘一井水氡R值为0.41,高于辽宁地区R值平均水平。综合该井水文地质特征、区域地质特征及历史震例研究对该井Rn值迁移机理进行分析,结果表明,区域应力场改变、井孔水文地质条件以及水-岩反应是造成水氡高值异常的主要原因。Based on the radon data of Panjin No.1 Well in Liaoning province, the dynamic variation characteristics of radon to the earthquakes of Ms≥5.0 in Liaoning and adjacent area were comprehensively analyzed. According to the R-value to evaluate the prediction efficiency of Panjin No.1 Well, the results show that the R-value of Panjing No.1 Well is 0.41, which was higher than the R-value of Liaoning province. Connecting the analysis of hydrogeological characteristics in Panjin No.1 Well, regional tectonic activities and research on historical earthquake, the migration mechanism of Radon has been discussed. It was concluded that the hydrogeological characteristics of Panjin No.1 Well and water-rock reaction is the main reason to let the radon value had a high value anomaly in Panjin No.1 Well.
