中文摘要：

新疆塔里木盆地是中国最大的内陆盆地，地质构造上是周围被许多深大断裂所限制的稳定地块．塔里木盆地的地震发生是盆地与造山带耦合俯冲的结果，与盆地周缘的活动性深大断裂相关，是盆地扩张使盆地与山脉的结合带不断受到挤压产生脆性破裂引起的，构成盆地中部为稳定区、而盆地周围山脉为地震频繁区的格局．塔里木盆地的活动断裂主要发育于山体与盆地的过渡地带，而近两年这6次规模比较大的地震也都发生在西昆仑和南天山的山前俯冲带，据以往统计资料，塔里木盆地内所有地震数据中的85％是分布在塔西南和西南天山的南缘区域．本文通过分析认为，塔里木盆地地震的发生与大型的断裂构造相关．断裂构造在重力、磁力等地球物理场上特征明显，深部结构又容易被大地电磁测深、地震测深等物探方法揭示．通过综合地球物理方法，可以有效地研究断裂的平面展布特征及深部结构，对于研究天然地震带的展布和地震发生机制，具有一定的意义．

英文摘要：

The Tarim Basin, the largest inland basin in China, is a stable block that is restricted by many deep faults around it. Earthquakes in the Tarim Basin have correlativity with the deep active faults, are the results of basin＇s expansion. A basin with mountains has combined with brittle fractures caused by squeezing; pose to stability in the midle of the basin, and earthquake-prone zones around the mountains. The major active faults in the Tarim basin developed close to the mountains, and the earthquakes of six times in the past two years have occurred in the West Kunlun subduction zone. According to previous statistics, 85% of all seismic data in the Tarim Basin is located in the southwest Tianshan. Cenozoic tectonics is easy to be recognized in gravity and magnetic fields. And the deep structures are also easy to reveal by magnetotelluric exploration, seismic exploration and other geophysical methods. Based on the geophysical data analysis, the seismogenic tectonics in the Tarim Basin and their characteristics are expatiated in this article. There are clear differences in tectonics between the east and west in the basin, and earthquakes occurred in the western region, for which the interpretation can be obtained from the geophysical data.
