从地质地貌特征与演化历史方面，结合世界遗产第viii条评价标准，将“中国南方喀斯特”第一批三个遗产地置于全球视角进行对比研究，揭示其全球显著价值：云南石林形成演化历史最复杂，石柱的形态最丰富，代表一种独特的石林形成演化机制；荔波锥状喀斯特锥峰单体最典型，地貌组合形态最丰富，代表典型的锥状喀斯特地貌特征，反映出大陆热带—亚热带锥状喀斯特的地质演化模式与过程；武隆峡谷喀斯特完整地展示了整个峡谷喀斯特发育演化系统，例证了正在进行的新构造运动背景下峡谷喀斯特系统的演化过程。因此，第一批遗产地代表中国南方喀斯特地区自古生代以来长期、多期演化历史；代表地球热带 —亚热带典型的锥状、石林和峡谷喀斯特地貌特征、形成演化机制及正在进行的地质过程；代表地球三大喀斯特片区之最大片区的独特的自然地理特征。

Karst constitutes one of the greatest landscape styles of the world and China is one of the places where its finest expressions can be seen. From the point of view of karst features and evolutional histories, and by comparative analysis on the three sites with worldwide similar karst areas under the eighth criterion of world heritage, the outstanding universal value is uncovered: Shilin stone forest in Yunnan is the most complicated in the evolution history richest in the forms,which represents a unique evolvement mechanism of stone forest development;which possesses not only the most typical karst cones, but also the most complex assemblages of the cone karst. Libo cone karst represents typical factors of cone karst landforms reflects geological evolvement models and processes in the tropical-subtropical continent; Wulong gorge karst shows integrally development and evolution system of the gorge karst, records evolutional forms of different phases of gorge karst, such as karst gorges, underground rivers, natural bridges, collapse dolines, caves and so on, and illustrats on-going evolution process on the neotectonic movement. As a result, south China karst (Phase 1) world heritage sites represent a long-term, multi-phased evolution history in south China since Paleozoic; the landform features of tropical-subtropical typical cone karst, stone forest karst and gorge karst; the development and evolution mechanism and on-going geological process of tropical-subtropical cone karst, stone forest karst and gorge karst landforms; and unique physical geography characters of the largest in the three vast karst areas in the world.
