摘要：This study investigates area-specific Sediment Yield (SY) in Mediterranean badland areas at different spatial scalesusing a SY-database compiled from scientific literature. Relationships between the plot and catchment characteristics and thecorresponding SY-data are analyzed. Results indicate that in Mediterranean environments SY is larger than in other environments,especially in badlands where a high variability of SY is observed depending on the spatial scale. In intensively gulliedbadlands,a complex plot or drainage area (A) – SY relationship is observed: for A ranging between 10–5 and 10 ha,SY is veryhigh (mean SY equals 475 t ha–1 yr–1),whereas for A > 10 ha,SY decreases with increasing A (mean SY < 100 t ha–1 yr–1).
