摘　　要：在收集整理全球大震数据目录资料的基础上,利用贵阳地磁台地磁报告分析资料和FHD数字化磁力仪记录资料绘制图,统计分析了磁情指数K、磁暴与地震的关系,认为K指数<5时,磁暴次数少,地震多;反之,K指数≥5时,磁暴次数多,地震发生的次数少。根据有关专家研究统计对比模拟记录与数字化记录,两种仪器的观测记录资料基本一致。Based on the data of the world large earthquakes, the geomagnetic report and the chart drawing by th the e e FHD digital magnetometer, the relationship between the magnetic index K, the magnetic storms and arthquakes is analyzed. The paper discussed a rule that when index K〈5, the possibility of magnetic storms＇ happening reduced; increased. According to the whereas, the index K ≥5, professors＇ study on the the possibility of magnetic storms＇ happening contrast between the simulative records and the digital records, the data recorded by the two different magnetometers are basically consistent.

关 键 词：磁情指数K 磁暴频次 地磁场 H水平分量
