Dinâmicas do uso e cobertura da terra da Chapada dos Veadeiros-GO entre 1984 e 2015

Abstract : By the year of 2002, Cerrado biome has suffered a loss of 54.9% of its original area due to deforestation and human action. National Park of Chapada dos Veadeiros Influence Region (RIPNCV), situated north of the state of Goias and 240 km from Brasília is an important expansion area of modern agriculture, been one of the main economic actions responsible for the biome's loss. In order to better understand the local dynamic, the aim of this study was developing, through geoprocessing techniques, an analysis over usage and land cover at RIPNCV and also detection changes. The main phases of the analyses were: data collection, Landsat image collection, image processing, usage and land cover classification methods and change detection via cross tabulation. The observed years were 1984, 2000 and 2015. From the data gathered through the mapping it has been observed that the anthropic coverage sharply increased; in 1984, it represented 17,4 %, raising up to 32,43% of the total area in 2015. Such variation representsa loss of 231.058 ha of natural vegetation. In a broad manner, natural coverage classes have suffered a steady decline in between the analysed years. Taking into account that farming actions have directly compromised the loss of local biodiversity and populations'life quality.
