摘　　要：通过分析2016年1月21日青海门源6.4级地震前后湟源地震台水氡值异常变化,发现在地震前后水氡值出现了下降—地震—继续下降—回升—恢复的短临异常特征,并对水氡异常可靠性进行分析,判定2016年1月10~30日水氡值低异常变化为地震前兆异常,可为地震预报提供一定的参考依据。Based on the analysis of water radon anomaly variation recorded by Huangyuan Station before and after Qinghai Menyuan MS6.4 earthquake on Jan.21,2016,we found that there appeared short impending anomaly in water radon data before and after the earthquake,such as decline- earthquake occurred- continue to decline-gone up again- recovery.Then we analyzed the reliability of water radon anomaly,and concluded that the lowanomaly variation of water radon from Jan.10 to Jan.30 in 2016 was the precursor anomaly of Menyuan M_S6.4earthquake,which could provide the reference for earthquake prediction.
