摘　　要：本文讨论了1960年—1969年共10年间在我国发生的586次震级M8≥4.75的地震与月龄、月球时角及地月距离之间的相关性,结果表明地震的频率与月球时角、月龄无明显相关性,而与地月距离有较好的相关性:当月球位于远地点附近时地震较多且与月龄无关;当月球位于地月平均距离附近时有几处发震几率较高,且地震较多发生在上下弦附近;当地月距离到最小值附近时地震都发生在朔望。The Correlations between frequency of earthquakes and moon's age, hour angle of moon and horizontal parallax of moon for 686 earthquakes (M≥4.76) happened during 1960-1969 in China have been discussed. The results show that there is less correlation between frequency of earthquakes and hour angle of moon or moon's age, but larger correlation between frequency of earthquakes and horizontal parallax of moon, i.e. earthquake occurrence is frequent and irrelative with moon's age when the moon comes close to apogee; earthquakes often happen when the moon reaches some places near mean distance, specially in first quarter and last quarter; earthquakes happen at syzygy when the moon comes close to perigee.
