Resumo
The expansion of agriculture and livestock in the central-western Brazil occurred from the
1970s, stimulated by the II National Development Plan or (II PND, 1975-1979) that resulted in
intense deforestation and fragmentation of the remnants of the original roof the Cerrado. The
microregion southwestern state of Goiás was one of the targets of this process and is now
characterized as a region with significant agricultural production. Rio Verde stands out not only to
have become a major agricultural producer, but also because of the changes continue until recently,
with expansion of agriculture, especially for grains and sugar cane, between 2005 and 2008.
Thus, this study was to evaluate the state of fragmentation of the remnants of Cerrado in the
municipality of Rio Verde using the techniques of geoprocessing (maps of land use and over),
ecology of the landscape with the use of software FragstatsTM 3.3 ande fitosociology. The results
show that the dynamic agricultural economy of Rio Verde is maintained, because there was no
significant reduction in the areas of agriculture (0.6%) from 2005 to 2008. You can also observe
that 22% of the landscape of Rio Verde is made up of Cerrado vegetation. The analysis of vegetation
showed that the city has great richness, however, there was great floristic variation between
sites studied due to environmental factors and degradation observed in the field.
