摘要
介绍了河北涿鹿矾山泉所处的地质构造环境、水文地质条件和水质类型等,对该泉近30年来的原始水氡观测数据进行了处理,对矾山水氡的干扰因素及映震能力进行了分析。结果表明:自1975年水氡观测以来,水氡一直保持夏高冬低的规律,虽因季节性排水有一定影响,但年变形态受干扰较小,在唐山7.8级地震和张家口地区个别中等地震前有一定异常反映,但对20世纪80年代后发生在张家口地区及邻近区域的中强地震反映不明显。
Geological tectonic condition,hydrogeological condition and type of water quality of spring of Fan shan of Zhuolu,Hebei are introduced.Raw observation data of radon in groundwater at the spring spot in the last thirty years is processed and noise and earthquake reflecting ability of radon in groundwater are analyzed.The result indicates there is such a rule that quantity of radon is higher in summer and lower in winter since 1975 when radon in groundwater began to be observed.Though seasonal drainage has certain influence,its effect on annual variation form is quite little.Radon in groundwater has certain anomaly reflections before the Tangshan earthquake of M7.8 and some moderate earthquakes occurred in Zhangjiakou region,but reflections are not obvious to the moderately strong earthquakes and strong aftershocks occurred in Zhangjiakou region and its neighbor region after the late eighties of the twentieth century.
