Abstract:

Based on 1:500,000 digital map of lithology distribution in Guizhou, spatial analysis of the maps of rock desertification and of lithology is conducted by GIS. Results indicate that there is obvious relativity between rock desertification and lithology. Intense rock desertification scatters maily in pure carbonate rock area, especially in pure limestone area whereas moderate rock desertification is more widely distributed in dolomite association than in limestone association and slight rock desertification is widely distributed in carbonate rock association layered with clastic rock.

Key words: rock desertification, lithology, spatial correlation, karst region, Guizhou
