Cobertura florestal do município de Rio Verde, GO: estrutura e composição da paisagem entre 2005 e 2008

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.
