摘　　要：新疆伊宁盆地主要分布有巩留南、喀什河、雅马特等 6条活动断裂 ,断裂走向近东西向与北西—北北西向。其中巩留南断裂、喀什河断裂、雅马特断裂等在晚更新世—全新世时期有过多次显著的新活动 ,切错了晚更新世—全新世堆积物。在喀什河断裂上 1 81 2年发生了 8级大震 ,形成长约1 0 0 km的地震形变带。在巩留南断裂、雅马特断裂、伊宁断裂上也有受控于断裂近代新活动的中等地震发生。There are 6 active faults distributing in the Yining Basin of Xinjiang, China. Among them, Gongliuhe fault, Kashihe fault and Yamate fault had many times of obvious new activities in late Pleistocene and Holocene, which dislocated late Pleistocene and Holocene deposit. In 1812, a M=8 earthquake occurred on Kashihe fault, thus forming about 100 km long seismic deformation belt. Controlled by the recent activity of the faults, some moderate earthquakes occurred in Gongliuhe fault, Yamate fault and Yining fault.
