摘　　要：前兆台网观测数据跟踪分析工作在前兆台站和区域中心全面展开。地震前兆数据跟踪分析产出的事件记录,展现了前兆台网观测数据的动态变化情况。本文从地磁学科数据跟踪分析的现状出发,提出该学科数据跟踪分析注意事项,并通过事件分析缺时段和过度分析、数据类型选择、事件起止时间、事件分析描述、图件绘制与标注、事件类型分类及地球物理事件分析等多个方面,对地磁跟踪分析中常见问题进行讨论,提出相应解决方案,最后针对地磁学科数据跟踪分析的推进工作提出措施。希望为地磁台站观测人员更好地开展数据分析研究及产出应用工作提供参考和借鉴,为地磁学科的预测预报与科学研究提供坚实基础,推进地震前兆台网日常工作重心从观测为主,向观测、应用并重转变。The tracking and analysis of precursor network observation data is comprehensively carried out at precursor stations and regional centers.The event records generated by the tracking and analysis of earthquake precursor data demonstrate the dynamic changes of precursor network observation data.This article starts from the current situation of data tracking and analysis,proposes precautions for data tracking and analysis in the field of geomagnetism,and discusses common problems in geomagnetic tracking and analysis through multiple aspects such as event leakage analysis and over analysis,data type selection,event start and end time,event analysis description,map drawing and annotation,event type classification,geophysical event analysis,and proposes corresponding solutions,measures are proposed for the promotion of data tracking and analysis in the field of geomagnetism.We hope to provide reference for the observation personnel of geomagnetic stations to better carry out data analysis research and output application work,provide a solid foundation for the prediction and scientific research of geomagnetic disciplines,and promote the shift of the focus of daily work of earthquake precursor networks from observation to both observation and application.
