Abstract

The composition and the forms of the relief are factors that contribute in the determination of the occurrence and the types of vegetation of a certain place. The association of vegetation with certain environments due to the sunshine received, water availability, among others, are directly related to the configuration of the relief of an area. The objective of this work is to demonstrate the relations between the configuration of the relief and the distribution of the native forest vegetation in the Serra do Caverá, in the southwest region of Rio Grande do Sul. The relief classification of the study area was based on the Geomorphons, from the DEM generated through the SRTM data, obtaining ten elements. After the vegetation mapping was carried out based on the interpretation of images of the satellite LANDSAT 8 OLI, the information was cross-referenced in a GIS environment, with ArcGis 10.3 software, ArcMap tool, also by calculating the frequency ratio (Fr). The highest correlation observed was with the valleys and flat areas (42.52%), followed by vegetation on hillsides, slope bases and excavated reliefs, which together added up to 40.85% of the total forest vegetation in the study area.
