摘　　要：通过h值和h’值分时计算,得出2016年1月21日门源Ms 6.4级地震序列的h值和h’值随时间的变化趋势,根据计算结果判定门源Ms6.4级地震为主震—余震型序列,序列衰减正常;给出地震序列强余震的可能震级为M_L4.3±0.3的预测结果。经检验,认为h值和h’值方法有助于此次地震序列的快速判定。In this paper, the h values and h＇ values are calculated by time division calculation method, then the trend of h value and h＇ value in Menyuan Ms 6.4 earthquake sequence on January 21,2016 are obtained. According to the calculation results, Menyuan Ms 6.4 earthquake sequence is determined as mainshock-after- shock sequence types, the sequence attenuation is normal, and the prediction results indicated that the magni- tude of strong aftershock is ML4.3 ± 0.3. Upon examination, the h value and h＇ value methods are helpful for determination rapidly of this earthquake sequence.
