【摘要】 介绍了银川基准台小口子泉的概况以及水氡观测情况。研究了自1990以来银川台小口子泉周边地区300 km范围内ML4.0以上地震与银川台水氡资料的映震情况。通过对典型震例深入研究,总结了小口子泉水氡与周边地区地震活动的对应关系,探讨了小口子泉水氡对周边地区地震的对应范围和对应的震级范围。小口子泉水氡异常对该泉点西北方向的地震反映灵敏,且都是低值异常。更多还原

【Abstract】 We introduced the Xiaokouzi spring survey and its observation circumstance of water radon in Yinchuan standard station.Studied the the earthquake reflecting ability of water radon in Yinchuan station for the earthquakes with ML≥4.0 to the Xiaokouzi spring in Yinchuan station 300 km since 1990.studied the representative earthquake cases,summarized the relation between water radon of Xiaokouzi spring and seismic activity in its adjacent region,disscussed the relation between range and magnitude of earthquake in adjacent region of Xiaokouzi spring and the water radon.The earthquake reflecting ability of water radon anomalies in Xiaokouzi spring is good to the earthquakes in northwest of the spring,and the anomalie is low value.更多还原
