| 摘 要： | 本文从大地构造背景，构造地貌，现今应力场，运动学特征，构造模型等５个方面论证了吐鲁番－哈密盆地的性质，认为吐－哈盆地是背驮于博格达推覆席体上的盆地，侏罗纪以来盆内的许多构造与沉积特征都取决博格达推覆构造与反冲推覆构造活动的强度。

| Abstract: | This paper discusses the Turpan-Hami basin from its tectonic setting, tectonic geomor-phology, present stress field, structural model and kinematic features. The authors hold that the Turpan-Hami basin is piggybacked on the Bogda nappe, and many structural and sedimentary features in the basin since the Jurassic are controlled by the thrusting intensity of the Bogda nappe and recoil nappe. Since the Cenozoic, the basin has been affected and transformed by the NE-trending sinistral strike-slip fault system; so it is considered to be a shear-piggyback basin. |
