摘　　要：对长白山地区空气氡浓度和气象条件进行监测研究,分析空气氡浓度与气象条件相关性。结果表明:气温是影响空气氡浓度的最大因素,且与空气氡浓度存在负相关关系;空气氡浓度与相对湿度、气压存在正相关关系;与风速存在负相关关系。相对湿度、气压、风速均与气温存在一定的相关关系,特别是相对湿度与空气浓度的关系可以看作气温与空气氡浓度关系的延伸。冰雪期,则冰雪是空气氡浓度的最大影响因素,可以显著降低空气氡浓度。The air radon concentration and meteorological conditions in Changbai Mountain were monitored and studied,and the correlation between air radon concentration and meteorological conditions was analyzed.The results show that air temperature is the biggest factor affecting air radon concentration,and there is a negative correlation with air radon concentration.There was a positive correlation between air radon concentration and relative humidity/air pressure.There is a negative correlation between air radon concentration and wind speed.Relative humidity,air pressure and wind speed are correlated with air temperature,especially the relationship between relative humidity and air concentration can be regarded as an extension of the relationship between air temperature and air radon concentration.During the ice and snow period,ice and snow are the biggest influencing factors of air radon concentration,which can significantly reduce air radon concentration.
