摘　　要：本文论述了张家界柱峰砂岩地貌的特征,形成机理及演化规律,指出柱峰地貌的形成,是由于平缓、强弱不一的岩层,受到发育的垂直节理的切割作用,以及湘黔古断裂挽近期活动,造成地壳快速抬升,该区地壳自更新世以来上升量为938m。The characteristics, formative mechanism and evolution law of columnar peak malmstone geomorphy in Zhangjiajie are analysed in this paper. It is considered that the columnar peak geomorphy results from cutting action along vertical joints of the rock and rapid elevation of the area caused by the activity of Hunan-Guizhou paleorift in the late period. According to the author's calculation, since Pleistocene Epoch the crust has risen by 938 meters. The author suggests that the influence of crust movement upon large engineering constructions in this region be investigated.
