对九江中心站3次非深部地下介质变化引起的气氡浓度异常进行分析，得到九江2井气氡浓度主要受水位、降雨量的影响，此外还受因温度引起水路管道挤压进而影响脱气压力变化等观测系统的影响。
Based on the analysis of three times gas radon anomalies caused by three non-deep underground medium changes in Jiujiang Central Station,it is concluded that gas radon in well is mainly affected by water level and rainfall.In addition, it is also affected by the observation system such as the change of degassing pressure due to the impact of water pipeline extrusion caused by temperature.
