摘　　要：该文简要介绍了蚌埠地震台土壤气定点观测点的基本情况和测量方法。在直观分析土壤气氡及二氧化碳的变化特征的基础上,运用使用逐步回归方法对气象因素与土壤气氡的相关程度进行验证。结果表明:蚌埠台土壤氡主要是受到气温的影响,土壤氡浓度与气温成正相关,与气压成负相关,且气温对气氡浓度的影响明显高于气压和湿度。This paper brief ly introduces the basic situation and measurement methods of f ixed-point observation points of soil gas at Bengbu Seismic Station.Based on the intuitive analysis of the variation characteristics of radon and carbon dioxide in soil,Stepwise regression method was used to verify the correlation between meteorological factors and soil radon.The results show that soil radon in Bengbu platform is mainly affected by air temperature.The concentration of radon in soil is positively correlated with air temperature and negatively correlated with air pressure,and the inf luence of air temperature on radon concentration is obviously higher than that of air pressure and humidity.
