The given eco-geoenvironmental setting has evident control action on land rocky desertification, rocky deserted land mostly distributes in the river-valley regions where karst very developed and tectogenesis was violent in Guizhou province. Warm and humid monsoon climate provides corrosion condition for rocky desertification;Tectogenesis sculptured steep and fragmentized karst land feature with sharp topographic relief, which offer rocky desertification a latent energy;Paleoenvironment supplied rich carbonate for rocky desertification, four carbonate sedimentary formations had developed from late Sinian to late Trias in Guizhou province, pure carbonate rock constitute the substantial foundation of land rocky desertification.
