| 摘 要： | 新疆地震活动分布区域广，主要分布在南北天山、西昆仑、阿尔泰、阿尔金山与塔里木盆地和准噶尔盆地的衔接地带。各地震带地震活动水平不尽相同，其中南天山与北天山地震带以及帕米尔一西昆仑地震带的地震活动水平较高，地震活动呈西强东弱的特点。自2011年以来新疆境内地震活动呈现出5级地震连发，6级地震活动频繁，且各地震带均有分布的特点。利用新疆历史地震目录，分析新疆境内各片区发生地震活动是否具有相关性，并从中获得各片区地震活动相关性的量度，以此可以将这些量度作为新疆境内各片区地震中长期预报的辅助性分析方法。

| Abstract: | The distribution of earthquake activity in Xinjiang area is wide, mainly distributed in the north and south of Tianshan, west Kunlun mountains, Ahai, Alkin and the adjacent area of Tarim Basin and Junggar Ba- sin, and the earthquake activity level is different. The level is higher in the south and north of Tianshan seis- mic zone and Pamir-west Kunlun seismic zone, and lower in west of Xinjiang. Since 2011, M5 earthquakes occurred continuously, M6 earthquakes occurred frequently in every seismic belt in Xinjiang. The seismic cor- relation between the zones is analyzed by the historical earthquake catalog, and the coherence can be used for middle-long term earthquake forecast in Xinjiang area. |
