摘　　要：本文探讨位于湘西武陵山脉中段的一种新的峰林地貌类型──石英砂岩峰林的形态特征，形成过程与形成机理，认为石英砂岩峰林是由水平状石英砂岩受垂直与交叉节理的分割之后，在无溶蚀作用下形成的．Wulingyuan quartz sandstone peak-forest, located at 29·18' - 29·25' N and 110· 27' 110·39' E, in the middle part of the Wuling Mountains in West Hunan, is of a new try of peak-forest landform. The rock of the peak-forest is quartz sandstone of middle Devonian. It is the product of the platform activity in the most stable period and is characterized by simple material composition, well grading grain size, good roundness and compact texture. The spectacular peak-forest is formed under the joint actions of gravity, erosion, weathering and Quaternary neotectonic movement, especially the non-crossing X erosion and transportation of dabris flow.
