Spatial variations in soil erodibility induced by rock outcropping on sloping cropland in the karst region of Southwest China
Sloping croplands in karst areas of Southwest China usually contain a multitude of rock outcrops with diameters larger than 25 cm.Rock outcrops and spatial location have substantial effects on soil properties and thus likely affect soil erodibility.Moreover, rock outcropping is a indicator of rocky desertification and has an important impact on soi
