摘　　要：整理和分析了1990年以来发生在新疆地区的30次ML≥5.4级地震序列(伽师强震群除外),得出了新疆地震序列类型划分的一般规则并将这些地震序列分为孤立型、主震—余震型和双震或多震型3种。这些地震序列主要分布于新疆4个地震构造带,以主余型为主,每个地震带内地震序列类型有所不同。通过对地震序列参数b、h、k和p的计算和分析,认为k值对该区地震序列类型的判断有一定参考价值。30 sequences of ML≥5.4earthquakes have occurred in the Xinjiang Area since 1990. After studying them, we find out the common regulation to classify the earthquake sequences and divide them into the isolated type, mainshock-aftershock type and double shock type or multishock type. The majority of them belongs to the mainshock-aftershock type. These sequences are mainly distributed in five different seismic belts, and their frequency, intensity and type in each belt are different. By calculating and analyzing the characteristic parameters b, h, k and p of each earthquake sequence, we think that k is of some value for reference for the determination of earthquake sequence types.
