摘　　要：钻井、地震和非地震资料表明:塔里木盆地车尔臣断裂东南的塔东南地区早古生代末以来经历了多次抬升。早期的构造变形和沉积充填主要受车尔臣断裂的控制,上新世以来主要受阿尔金断裂带控制。塔东南地区可划归为1个一级构造单元,称之为东南隆起。东南隆起的构造和沉积具有东西分段、南北分带的特征,根据地层分布、构造变形和基底埋深,把东南隆起由西至东依次划分为民丰凹陷、且末凸起、瓦石峡凹陷以及罗布庄凸起4个二级构造单元。The drilling, seismic and non-seismic data indicate that the southeastern Tarim basin, located at the southeast of Che＇erchen fault, has experienced several times of ascending since the end of Early Paleozoic.The structural deformation and deposition in this area at that time were controlled by Che＇erchen fault and controlled by the Altun fault belt since Pliocene. Therefore, the southeastern Tarim basin is classified as a first-order tectonic unit of Tarim basin, called southeast uplift. The uplift is characterized by ＂sections in east-west direction and belts in south-north direction＂. According to the distribution of strata, structural deformation and the depth of basement, the southeast uplift can be divided into four second-order tectonic units from west to east such as Mingfeng sag, Qiemo swell, Washixia sag and Luobuzhuang swell.
