摘要
Sandstone of huge thickness is extensively distributed in the south of Chishui County,Guizhou.Influenced by endogenetic and exogenic geological processes such as tectonic movement,water erosion,weathering degradation and gravity collapse,various types of landscapes have been formed on Danxia Landform.Combined with types and characteristics as well as genesis and evolution,Danxia Landform is classified,in terms of main force,into following types:tectonic Danxia Landform,water-erosion Danxia Landform,efflorescent Danxia Landform and gravitational Danxia Landform.The characteristics of the typical and representative landscapes are also described in this paper.The process of the formation and evolution of Danxia Landform in the south of Chishui County is analyzed in detail.The mechanism of the formation and evolution is preliminarily unveiled from the angle of geology,which plays an important role in dissemination of the knowledge of earth science and performance of geological research.
