摘　　要：【目的】以2023年满洲里地电场受到的地电暴事件为例,分析其基本特征表现。【方法】结合地磁磁暴事件、K指数表现等资料数据,同时参考日差值、相对变化率、最大变幅等其他质量参数,将该地电场正常数据变化曲线、地电暴事件下的数据变化曲线、其他典型干扰下的数据变化曲线进行综合对比分析。【结果】地电场具有广域性、同步性、持久性等特征,在表现程度上与地磁K指数存在正相关。该地电场地电暴事件频次多于其主要场地环境事件干扰频次,但对数据曲线的压制程度往往不及场地环境事件。【结论】研究结果可为地电暴、地电场的进一步科学研究提供基础信息资料,为其他地电场的日常数据处理提供参考。[Purposes]Taking the geoelectric storm event of 2023 in Manzhouli Geoelectric field as an example,the basic characteristics of the event are analyzed.[Methods]Combined with geomagnetic storm events,K-index performance and other data,and referring to other quality parameters such as daily difference,relative rate of change,maximum amplitude of change,etc.,the change curve of the normal electric field data,the data change curve under geomagnetic storm events and the data change curve under other typical disturbances was comprehensively analyzed.[Findings]The geoelectric field has the characteristics of wide region,synchronization and persistence,and its performance degree is positively correlated with the geomagnetic K index.Meanwhile,the frequency of electrical storm events in the local electric field is higher than the interference frequency of the main environmental events in the site,but the degree of suppression of the data curve is often lower than that of the environmental events in the site.[Conclusions]This paper provides reference for the daily data processing of other geoelectric fields and basic information for further scientific research of geoelectric storm and geoelectric field.
