Carbonate rock weathering soil is dominant in the area, but there is a littleweathering soil of other rock in the farm ecosystem and rainforest ecosystem. The-carbonate rock weathering is the principal pattern to form soil in desert ecosystem. We measured contents of major chemical elements of rock and soil of weathering crust section, and referred to the previous researchs at home andabroad.By comparison with the chemical mean of soil of the weathering basalt of eastern Chinaand the world, this note has obtained the law of elements migrating, dispersing and enriching duringcarbonate rock weathering in middle Guizhou. 关 键 词：CARBONATE rock WEATHERING GEOCHEMICAL characteristics Guizhou.
