AbstractThe study of the variability of soil erosion in mountainous areas provides the basis for soil and water conservation work and forest ecological construction in a targeted way. In this study, Liangshan Town catchment, a typical catchment in the Hengduan Mountains region, southwest China, was selected to investigate the variation of soil erosion in different vertical zones using the Cs-137 tracing technique. The mean Cs-137 reference inventories varied between 573.51 and 705.54 Bq/m(2), with the elevation increasing from 1600 to 2600 m. The rates of soil erosion exhibited a significant variation. Under the same land cover condition, the average annual soil erosion modulus of high-elevation forest (elevation > 2200 m) was 400.3 t/(km(2)a). However, the average annual soil erosion modulus of a low-elevation sparse forest (elevation < 1600 m) was as high as 1756 t/(km(2)a). The average annual soil erosion modulus of the sloping farmland, mainly distributed at elevations of 1600-2200 m, was estimated to be 2771 t/(km(2)a). These results indicate that effective soil management measures need to be implemented on the cultivated sloping land in the future.
