关于锥状喀斯特与塔状喀斯特的形态结构成因问题——以贵州安顺地区和广西桂林地区对比分析为例

LANDFORM STRUCTURE OF CONE KARST AND TOWER KARST A COMPARATIRE ANALYSIS OF ANSHUN AREA,GUIZHOU,AND GUILIN AREA,GUANGXI

通过对贵州安顺地区和广西桂林地区喀斯特的研究对比，从地貌形态结构入手，探讨锥状喀斯特与塔状喀斯特的形态成因联系。锥状喀斯特是湿热带喀斯特的原生地形，塔状喀斯特并非锥状喀斯特老年期地形的简单延续，而是代表一个特殊水文地貌环境开始的锥状喀斯特发育过程的特殊阶段。贵州之所以以锥状喀斯特为主，就是因为晚近期强烈的新构造抬升背景下。

The investigations in situ on Kast patterns prevailing in Anshun area,Guizhou Province,along with comparisons to those of GuiLin area,Guangxi Region,were presented.and their relations in the morphological cause of formation were further discussed in the view of the structure of landform patterns.Our results showed the cone Karst is the original terrain extremely occurring in the tropical Karst regions,and the tower Karst is not only the simple continuity of the old-satge cone karst patterns,but also represents the start of a special hydrdogical environment and a special stage for the evolution of the cone Karst,The cone Karst dominates in Guizhou mainly due to the lack of hydrodynamic processes and landform effeces for the evolution of the tower Karst under the cirumstances of the latest neotectonic rise.
