Uso da Terra no Rebordo do Planalto do Rio Grande do Sul

Alessandro Samuel Rosa

Abstract


Using images from Google Earth Pro we described land occupationand its use in a small basin located in the Plateau Border areas of the RioGrande do Sul State, Brazil. Our results showed that in spite of intensereplacement of native vegetation into agriculture, the changes in land usealong the years resulted in the restoration of native vegetation. Nowadaysforest is the main land use in these areas. The sequence that best representsthe changes in land use is: agriculture  pasture  fallow  forest. Soilsin areas under forest are shallow and stony. In the areas under cultivationsoils are deeper and not stony. This information indicates that land-use maps shall be used for predicting soil characteristics in digital mappingprocedures. Images from Google Earth Pro allowed discriminating adequatelyland-use classes, what makes this tool adequate for land-use studies.
