摘要：

Soil loss must be predicted with high resolution for landscape planning in areas of complex toporaphy. In the first part of this paper the length-slope factor LS is differentiated for an application on complex slope geometries, with specific consideration given to catchment convergence and divergence. The result is a differentiated Universal Soil Loss Equation: dUSLE. The second part describes its computational implementation on a surface model, which has the structure of a triangulated irregular network (TIN). The third part shows an example of how this method can be combined with the functions of a geographical information system. This leads to an application of the differentiated USLE, which produces high resolution maps of soil loss by rain fall, if the values of the R-, C-, K- and P-factors are given. © 1990.
