喀斯特（Karst） Stone: This is a tall stone bud, up to 20-30 meters, such as clouds, called the stone forest. It is formed due to the high purity, thickness and level of limestone in tropical rainy conditions. Fengcong, Fenglin fengcong and Fenglin and Butte is a mountain limestone aggregate suffered a strong dissolution and the formation of. The peak is at the bottom of base connected peaks, peaks is by peak cluster further to the depths of dissolution, evolution. The Butte karst area isolated limestone peaks located in Karst basin. Dissolving bucket and karst depression funnel karst surface is circular or oval depressions, karst depressions is surrounded by closed depressions surrounded by low mountains, hills and peaks. If the channel at the bottom of the dissolving bucket and the dissolution depression is blocked, the water can be accumulated into a pond, and the large one can form a karst lake. Sinkholes, sinkholes and dry valley Valley karst area surface water to underground cave or underground channel, it is the karst water of continuous dissolution and vertical fissure with collapse and form. In the river of sinkholes, often the river will be into the underground rivers, the formation of dry valley or valley. [4] Underground Karst form Landform (3) Karst Cave: karst cave, also called cave, is the underground channel formed by erosion and erosion of groundwater along the level, joint or fault of soluble rock. In the cave of Karst the main form of stalactites, stalagmites, stone pillars, stone curtain, Shi Huihua and sinter. 3 causes of formation Chinas modern Karst was developed on the basis of quasi Plains after the Yanshan movement. Early three Century Karst, Southern China as a tropical climate, forest began development; north subtropical climate, has a gentle hill depression landforms are still left over in some areas of Jinzhong and the southern section of Taihang Mountain mountain watershed. But at that time, the north and south of the Yangtze River were des
