| 摘 要： | 该文阐述张家界地貌形成于 2 5MaBP以来的第四纪 ,现正处于青壮年期的演化阶段。其形成基础是厚层、坚硬、产状平缓、垂直节理发育的石英砂岩夹薄层粘土岩。形成原因是地壳的新构造抬升与外力的侵蚀、剥蚀。形成机制是流水溯源侵蚀—岩石块体崩塌—谷坡后退。今后将会向低丘—残丘的方向演化 ,但这将是一个较长时期的地貌过程

| Abstract: | This thesis sets forth Zhangjiajie physiognomy forms the 4th century since 2.5MaBP, now it is on the stage of youthful evolvement. Its formation basis is the clay rock which is thick layer, hard, the shape is gentle, vertical development and quartz. The cause of formation is the new structure rising of the earth's crust and the erosion and denudation of the external force. The formation mechanism is the flowing water trace to the source erosion-rock collapse-ancient slope withdrawal. It will evolve to the direction of low hills to wrecking hills, but it will be a long term physiognomy process. |
