摘　　要：【目的】进一步提高地震台站电磁观测数据的质量和数据分析能力。【方法】基于内蒙古自治区2019—2022年的前兆电磁数据跟踪分析资料,通过对比内蒙古地区各个台站电磁干扰原因和典型曲线,对电磁学科常见干扰进行总结分析。【结果】内蒙古自治区地电台站面临的主要问题为降雨干扰及漏电干扰;各个地磁台站之间跨度较大,所处地区为中高纬度地区,台站受磁暴、亚暴等影响较为频繁。【结论】可为相关工作人员对电磁数据干扰判断和处理提供参考。[Purposes]This paper aims to further improve the quality and data analysis ability of electromagnetic observation data of seismic stations.[Methods]Based on the tracking and analysis data of precursor electromagnetic data from 2019 to 2022 in Inner Mongolia,this paper summarizes and analyzes the common electromagnetic interference by comparing the causes and typical curves of electromagnetic interference at various stations in Inner Mongolia.[Findings]The main problems faced by radio stations in Inner Mongolia are rainfall interference and leakage interference;The span between various geomagnetic stations is relatively large,which are located in mid to high latitude areas,and are frequently affected by magnetic storms,sub typhoons,and other factors.[Conclusions]This study can provide reference for relevant staff to judge and process electromagnetic data interference.
