Abstract
The Yellow River Basin is one of the areas worst affected by soil and water loss in China. The slope length and slope steepness factors are the basic data for the study on soil loss equation, and they are also important parameters in soil erosion models of USLE and CSLE. In this study, we obtained the dataset of four key factors of soil erosion equation, namely slope steepness factor, slope length factor, LS factor and slope length through regional LS factor calculation tool based on ALOS 12.5 m DEM data. This dataset can be used for regional soil erosion assessment, land use as well as the measures and planning of soil and water conservation.
