摘　　要：对青海省西宁和格尔木的水氡测项用"十五"攻关方法①进行震例分析研究,总结出了西宁和格尔木水氡短期异常特征及预报指标,同时计算出了这2个台水氡测项的短期预报效能评分,西宁水氡具有较高的短期地震预报信度,格尔木水氡的短期预报效能评分信度较低,但格尔木水氡对唐古拉地区的6级地震有较好的对应。The radon data of Xining and Ge'ermu stations are analyzed,the characteristics of short-term anomalies of radon at the two stations and the prediction index are summarized.And their short-term predictabilities(R values) are calculated.R value of Xining station is higher than that of Ge'ermu station,but radon variation of Ge'ermu station is better reflected to Ms≥6.0 earthquakes in Tanggula area.
