Because of the occupation occurred in the last thirty years at Xingu river basin, this region has been suffering a large deforestation pressure, especially on its headwaters areas. This study aims to apply GIS techniques to evaluate how land use change has influenced the deforestation dynamics of Xingu water basin in Mato Grosso State. For that, a GIS based study was carried out were the deforestation data for the period between 2000 and 2005 was spatially integrated with settlement areas, indigenous lands, sites of mineral deposits and prospect areas. From this spatially integration, it was possible to analyze statistically how the deforestation has manifested on each kind of occupation, considering the original forest area. The techniques used, including inventory and database organization on GIS environment, and spatial analysis tools made it possible to analyze the deforestation in the Xingu basin in Mato Grosso State between the period of 2000 and 2005, and identify the most affected areas, considering different land uses.
