Resumo: he municipality of Coari showed significant transformation in land use and occupation in recent decades, probably caused by the activity of prospecting and exploration of oil and natural gas, as well as due to its population increase. The vegetation indices enable characterization and quantification of biophysical parameters of the surface, once they reduce the size of the multispectral information provided by satellites. Therefore, the aim of this study was to study changes in land use and occupation in Coari-AM through the normalized difference (NDVI) vegetation index calculated from Landsat 5 TM in 1986 and 2009. Two images obtained by satellite Landsat 5 TM were used, composed of seven spectral bands and available by Space Research Institute site - INPE. Classification of land use and occupation was held from the NDVI obtained from Landsat 5 TM image and defined four classes: urban area or exposed soil, dense forest, clearings and water. The results enabled to view changes in the land use and occupation in Coari. There was an increase of exposed soil / urban area and decreasing the area of dense forest, showing the advancement of human activity on the region in the last two decades

Os índices de vegetação possibilitam a caracterização e quantificação de parâmetros biofísicos da superfície, pois reduzem a dimensão das informações multiespectrais fornecidas pelos satélites. Sendo assim, o objetivo deste trabalho foi estudar a mudança do uso e ocupação do solo no município de Coari-AM por meio do índice de vegetação da diferença normalizada (NDVI) calculado a partir de imagens Landsat 5 TM em 1986 e 2009. Foram utilizadas duas imagens obtidas pelo satélite TM/Landsat 5, compostas de sete bandas espectrais e disponibilizadas no site do Instituto de Pesquisas Espaciais - INPE. A classificação quanto ao uso e ocupação do solo foi realizada a partir do NDVI obtido da imagem Landsat 5 TM e definidas quatro classes: área urbana ou solo exposto, floresta densa, clareiras e água. Os resultados obtidos possibilitaram visualizar as mudanças no uso e ocupação do solo da região de Coari. Houve um aumento de solo exposto/área urbana e diminuição da área de floresta densa, demostrando o avanço da atividade antrópica sobre a região nas duas últimas décadas.Universidade Federal de Uberlândia2016-11-09info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.ufu.br/index.php/sociedadenatureza/article/view/31538Sociedade & Natureza; Vol. 28 No. 2 (2016)Sociedade & Natureza; v. 28 n. 2 (2016)1982-45130103-1570reponame:Sociedade & natureza (Online)instname:Universidade Federal de Uberlândia (UFU)instacron:UFUporhttps://seer.ufu.br/index.php/sociedadenatureza/article/view/31538/pdf_1Copyright (c) 2016 Revista Sociedade & Naturezainfo:eu-repo/semantics/openAccessGuilherme, Adriano PereiraMota, Andréa Baima dos SantosMota, Deniz dos SantosMachado, Nadja GomesBiudes, Marcelo Sacardi2021-04-30T14:00:57Zoai:ojs.www.seer.ufu.br:article/31538Revistahttp://www.sociedadenatureza.ig.ufu.br/PUBhttps://seer.ufu.br/index.php/sociedadenatureza/oai||sociedade.natureza.ufu@gmail.com|| lucianamelo@ufu.br1982-45130103-1570opendoar:2021-04-30T14:00:57Sociedade & natureza (Online) - Universidade Federal de Uberlândia (UFU)false
