DIAZ-RIVERA, J. R.; PEREZ-COSTA, D.; RODRIGUEZ-ALVAREZ, Y.  and  FEBLES-GONZALEZ, J. M.. Determination of soil erosion indexes applying GIS analysis to the locality of San Andrés in the province of Pinar del Río. Rev.

In the occidental section of Sierra de los Órganos (locality of San Andrés, province of Pinar del Río) most of its soils are red ferralitic leached in hillside condition. Its exposure to erosive processes can be verified. However, there are not enough references about assessment of natural factors influence over those processes. Through the present work there have been calculated potential and current erosion risk indexes taking published data in1989 (Departamento de Suelos del Ministerio de la Agricultura, 1989), and gathered data by fieldwork in 2005. These indexes were used for soil maps construction by mean of GIS tools. The results show a trend to morphogenesis and make predictable a similar behavior in the next several years whether following the current land use customs.

Keywords : suelos Ferralíticos Rojos Lixiviados; riesgo de erosión actual; riesgo de erosión potencial; mapas de suelos.
