摘要

The objective of this research was to study the influence of the geomorphic surfaces in the spatial variations of the soil loss by erosion in the Pereira Barreto region, São Paulo State, Brazil. Soil samples were collected in 67 points, in a depth of 0.0-0.2m, located in a 350m regular grid to measure the particle size distribution and organic matter content. The local erosion factors were determined: erosivity (R), erodibility (K), topographical factor (LS), use and tillage (C), and conservation tillage (P), natural potential of erosion (PNE), soil loss with and without conservation tillage (A), soil loss tolerance (T) and erosion risk (RE). The variables A, PNE and RE presented great spatial correlation with the topographical factor (LS), indicating the influence of the relief on the erosion factors. The soil losses (A and A *) presented coherent behavior with the concept of geomorphic surfaces, evidencing the dependence relationships of the soil erosion process to the geomorphic environmental.
