摘　　要：武都殿沟泉是甘肃陇南地震台的流体综合测点,主要观测项目有模拟水氡、数字化气氡和数字化气汞。模拟水氡资料始于1987年,数字化气氡观测始于2001年1月,数字化气汞观测始于2007年6月。本文分析了该测点的水氡、气氡、气汞等观测资料。结果表明,水氡资料连续可靠,在一些地震前记录到明显的震前异常,特别是一些大震前与其他水氡测点的异常同步。气氡资料波动较大,部分时段与水氡资料变化一致,但动态稳定性明显不如水氡。数字化气汞资料开始观测至2009年7月比较正常,从2010年以来资料基本无法使用。Diangou spring in Wudu is the comprehensive seismic measuring point in Longnan county in Gansu province.The main observation projects include analog water radon,digital gas radon and digital gas mercury.The data of analog water radon were observed in 1987,and the data of the digital gas radon were observed in January 2001 and the data of digital gas mercury were observed in June 2007.And these data were analyzed,and the results showed that the data of water radon are continuous and reliable and reflected some obvious anomalies before the earthquakes,especially before large earthquakes and had synchronous anomalies with other observational points.The variation amplitude of gas radon is bigger than the water radon,some time they were changed synchronously,but the dynamic stability of gas radon is obviously not as good as the water radon.The quality of the digital data of gas mercury is good till July 2009,and after then the data is not used.
