山西地下水氡中短期异常识别标志及预报方法研究
|
摘要
采用“九五”地震科技攻关地下水化学及 EIS2 0 0 0提供的多种数据处理和异常识别方法 ,对山西省地下水氡观测资料进行了较详细的处理 ,筛选出较好的数据处理方法和异常标志。结果表明 ,除常规的数学处理方法外 ,用水氡的基值变化率和滑动变化率提取异常效果较好 ,如果基值变化率 R0 ≥ 0 .0 6 ,持续时间大于等于 12个月 ,滑动变化率 R≥ 0 .0 5 ,持续时间大于等于 12个月 ,则视为异常
The fine processing for the observation data of the Radon in groundwater in Shanxi province using Kinds of data processing method from the key task research on groundwater chemistry of seismological science of Ninth Five-Year-Plan and EIS2000 was made,the relative good data processing methods and anomaly indexes were screened.The research showed that the results of the anomaly drawn from the basic value change rate and the moving change rate of Radon in ground are better except the conventional data processing methods.If the change rate of the basic value R 0≥0.06 and its duration ≥12 months,the change rate of the moving value R≥0.05 and its duration ≥12 months,it can be regarded as anomaly.
