In other words, underground water is an essential water resource, accounting for 41%-83% of the total. Meanwhile, the formation of limestone soil is slower.(2) Guangxi is a typical karst region. A large difference is noticed in vegetation coverage between karst regions and non-karst regions. The average coverage of bush and forest communities is 14.81% and 12.13% in the karst regions, 1.92% and 31.3% in the non-karst regions.(3) The wide distribution of rocky desertification in Guizhou Province indicates the karst environment is strongly affected by carbonate rocks'properties.
