摘　　要：利用丰满台吉丰井1986—2016年的水氡观测资料,分析其动态变化特征,并研究了丰满台水氡异常与地震活动的对应关系,结果显示:大部分异常的出现与消失在时间上与东北及华北的中强地震以及西太平洋地震带北段等地区的强震活动相关联,映震效果较好。研究结果可为今后利用丰满台水氡异常资料进行地震预报提供依据。The dynamic change characteristic of groundwater radon data from 1986 to 2016 in Fengman seismic station is analyzed and the relationship between its anomalies and seismic activity is studied.The results shows that：the appear and disappear time of the anomalies are related to the middle and strong earthquakes in Northeast China and North China and the strong earthquakes activity in the north part of the western Pacific earthquake zone etc.Its earthquake reflection effect is better,which may provide reference for earthquake forcasting using groundwater radon anomalies in Fengman seismic station.
