张家口矾山泉水氡资料变化特征分析

Study on the characteristic of radon data observed from Fanshan Spring in Zhangjiakou

深入研究了矾山泉水氡资料的趋势变化和年变化特征,对水氡与气温的正相关特性进行了分析,并对该泉水氡资料的映震能力作了统计分析。结果表明,矾山泉水氡资料从长期到中短期的异常变化与本区的中强地震活动有较好的对应关系,根据中短期异常可作出6个月以内中等地震发生的概率为68.70%。

The tendency and annual variation of radon data from Fanshan Spring are studied, and the correlation of radon with air temperature is also analyzed. The analysis to the earthquake reflecting ability of the radon data shows that the long term and medium or short term anomalies picked from the data are corresponding well with the medium and strong earthquakes in the region. According to medium and short term anomalies, the medium earthquake probability within 6 month is 0. 687.
