Abstract：“South China Karst”is a serial World Natural Heritage site,nominated in phases by the government of China to the UNESCO World Heritage Committee. In this paper,based on the geomorphologic characteristic research of Huanjiang Karst,is compared with Libo Karst and other sites of “South China Karst”.It is concluded that:(1)Huanjiang Karst and Libo Karst have the same geomorphic landscape type-cone karst.(2 )The extension adds the geomorphologic rej uve-nation value to Libo Karst.(3)Huanjiang Karst in the nomination will make an important addition to the integrity problem about the boundary of the southern buffer zone of Libo Karst World Heritage Site,resulting from the administrative boundary between Guizhou and Guangxi Provinces,including geology and geomor-phology,biology and ecology,natural landscape,etc.,further more meeting the integrity requirements of world heritage;(4)In the history of South China karst, Libo-Huanjiang Karst recorded the sedimentary history of the second cycle of car-bonate rocks.After experiencing the transformation processes of karst landforms from Dongwu,Indosinian and Neotectonic movements,they represent the cone karst landform in the transition zone from the Yunnan-Guizhou Plateau to the Guil-in Basin in southern China and the ongoing evolution process of cone karst geomor-phology.It is the model site for tropical-subtropical cone karst in the world.
