山西定襄七岩泉水氡异常变化分析

摘要

By combining method of qualitative and quantitative analysis, the anomaly of Dingxiang spring appearing in 2008 is investigated. Based on basic data of observation circumstance, potential interfere factor is checked and the effect extent of interfere factor to observation value is quantitatively analyzed. The creditability of trend anomaly variation is analyzed. Compared with the past research results and earthquake examples, it is conc.luded that the high value anomaly variation of radon in water of Dingxiang spring is creditable. The medium- term trend anomaly variation may clue that strong earthquake occurrence in North China in the future, so that the variation of the anomaly must be traced closely.%采用定性和定量相结合的方法，对定襄泉2008年出现的异常进行现场调查，收集观测环境基础资料，排查可能的干扰因素，定量分析干扰因素对观测值的影响程度。对趋势异常变化的可信度进行分析，并结合研究成果和以往震例，分析认为定襄泉水氡高值异常变化是可信的，应密切跟踪此异常的发展变化。
