Zusammenfassung
This study will allow knowing the importance of present and potential erosive processes that will help to make adequate decisions in protected areas, and to establish protection measures if it would be necessary in order to avoid soil losses. Among all available methods to study soil erosion, the USLE (Universal Soil Loss Equation) one was chosen, because it is not necessary a huge volume of input data and it has been applied in several studies offering good results (it is important to know its limitations and to adapt it to the study area). Cartographies for each of the parameters in USLE equation were generated with the use of G.I.S, from which was calculated potential and present erosion. Results show that potential values of soil losses are low in the most of the area, coinciding with geomorphologic domains of pediment and hills. The areas more subject to erosion (present erosion) correspond to the ones with higher altitude, in slopes with limited vegetation in the north slope of Sierra de Francia, east of Martiago and in the fall scarp and fluvial incisions; decreasing considerably in the north slope of Sierra de Gata .
