摘要:
利用近3年来宿迁市断层土壤气观测台阵10个台站数据资料，分析氡、氢、二氧化碳逸出浓度变化特征，研究不同地质年代断层和不同种类土壤气逸出浓度相互关系，以及数据年变规律受气温、气压、降雨量等影响程度；结合泗洪ML3.7级地震，土壤气氡数据出现同步趋势变化现象，分析台阵观测映震效能。结果表明：土壤气氡、氢、二氧化碳浓度动态变化与气候因素密切相关，氡观测受降雨量和二氧化碳载气作用影响，台阵数据同步趋势变化对震前异常捕捉具有指示意义。
Abstract:
Based on the data from 10 stations of the Suqian Seismic Array for fault soil gas observation in the past three years，this paper analyzed the characteristics of radon，hydrogen，and carbon dioxide emission concentra?tions and studied the relationship between the emission concentration of different types of soil gases and faults in dif?ferent geological periods. Moreover，the extent to which the annual variation of the data was influenced by tempera?ture，air pressure，and rainfall was explored. Combined with the ML3.7 earthquake in Sihong，the radon data in soil gases showed the phenomenon of synchronous trend change，and the seismic reflection ability of the seismic ar?ray was analyzed. The results show that the dynamic changes of radon，hydrogen，and carbon dioxide concentra?tions in soil gas are closely related to climatic factors. Radon observations are affected by rainfall and the carrier gas role of carbon dioxide. The synchronous trend changes in the array data have indicative significance for the detec?tion of pre-earthquake anomalies.
