摘要
本文基于山西省5个地电场观测台站近10年的观测资料,对影响数据变化的干扰因素进行分析。结果表明,山西省地电场干扰因素主要有观测系统、自然环境、场地环境、人为干扰、地球物理观测影响,干扰数据形态主要表现为缺数、突跳、台阶、趋势变化等。山西省地电场典型干扰特征的提取可为台站工作人员快速处置提供依据,为数据变化分析和异常信息提取提供一定参考和借鉴。
Based on the 10-year observation data from 5 ground electric field observation stations in Shanxi Province,this paper analyzes the interfering factors that affect the data changes.The results show that the interference factors of geoelectric field in Shanxi mainly include observation system,natural environment,site environment,human interference and geophysical influence.The interference data form is mainly manifested as morphological changes such as deficiency,jump,step and trend change.The extraction of typical interference characteristics of the ground electric field in Shanxi can provide a basis for the staff at the stations to take quick actions,and also offer certain references for the analysis of data changes,and serve as a reference for extracting abnormal information from the data.
