- Abstract:

Discovering the influence of lithologic discrepancy on soil physical and chemical properties and anti-scourability in karst area is significance of studying the processes of rocky desertification. Five lithological soils in karst region of central Guizhou Province were chosen to measure soil physical and chemical properties and anti-scourability. The results indicated: there were significant differences in soil mechanical composition, bulk density, porosity and content of organic matter among different lithologies. Soils derived from carbonate rocks (dolomite and limestone) had the best physical properties, followed by soils developed from sandstones(arkose and purple feldspar quartz sandstone). Properties of soils derived from coal measures strata are the poorest. Besides, the anti-scourability of soil from coal measures is the weakest. So more attention should be paid on soils developed from different lithology in soil conservation, especially for the coal measures.
