· 1 Introduction Carbonate rocks are highly abundant and widely distributed throughout the world. In China, carbonate rocks cover 3.44 million km 2, accounting for 1/3 of the land area (Li et al., 2022).Exposed carbonate rock (about 910,000 km 2) is mainly distributed in South China, centering karst areas in Guizhou province ().
