山东地区地电场和地磁场观测数据对比分析研究

The comparative analysis of geoelectric field and geomagnetic field observation data in Shandong Province

介绍了山东地区同时拥有地电场和地磁场观测的5个电磁台站的基本概况,选取了各台2011年度的观测数据,并对其观测资料质量进行了简要评价。重点对5个台站的地电场和地磁场观测数据进行了全面、系统的对比分析,探寻了地电场、地磁场日变规律以及地电场、地磁场观测对各类干扰响应的区别与联系,为两种观测资料的分析处理提供了相互参考、相互借鉴的依据。

This paper describes the basic profiles of the five electromagnetic stations in the Shandong area which have both geoelectric field observation and geomagnetic field observation.We select the observation date of the year 2011 in each station,and evaluate the observation data quality briefly.The paper focuses on the comprehensive and systematic comparative analysis of the geoelectric field observation and geomagnetic field observation data in the five stations,explores not only the daily change of geoelectric field and geomagnetic field but also the distinction and contrast of these observations in terms of all kinds of interference,and provides mutual references for the analysis of observation data.It can increase the timeliness and accuracy in the process of observation data analysis,and thus improves the inner quality of observation data,making it more practical in seismic monitoring and earthquake prediction.
