摘　　要：以库尔勒新43泉气氡资料为研究对象,结合新43泉基础资料、背景资料和异常跟踪调查结果,研究库尔勒新43泉气氡资料与地震活动关系。结果表明:站点300 km左右的成组地震前2~3个月气氡出现异常,多数表现为氡含量升高、突变、波动,异常幅度和异常时间与震级成正比。今后观测资料出现类似异常应注意不同时间尺度的动态变化特征。Taking gas radon data of Korla New 43 Spring as the research object,combining the basic data,background data and anomaly tracking investigation results of New 43 Spring,the relationship between gas radon data of Korla New 43 Spring and seismic activity is studied.The results show that the radon in the gas appears anomaly 2 to 3 months before the group earthquake about 300 km from the station,most of which are manifested by the increase,mutation and fluctuation of radon content,and the anomaly amplitude and time are in direct proportion to the earthquake magnitude.In case of similar anomalies in the future observation data,attention should be paid to dynamic change characteristics of different time scales.
