Resumo: | The historical process of deforestation of the cerrado in the last century was directed to the northern region of the biome, which concentrated the largest vegetation fragments, protected areas and priority areas for biodiversity conservation. This anthropic pressure demands studies that assess the structural configuration of the fragmentation process around protected areas. The Tocantinzinho River basin fits into this scenario and was selected to assess changes in the landscape structure considering historical data on land cover and use, to identify space-time patterns that may influence the functioning of the landscape. Satellite images (LANDSAT) were classified between 1985 and 2016, with the application of landscape descriptive indexes, which allowed spatial comparison in historical succession for the basin area. The results indicate that the replacement of patches of native vegetation by anthropic patches mainly impacted the grassy field vegetation and that the process of anthropization of the area is recent with evidence of development from the 2000s; ensure that the pastures are already being replaced by agriculture and that the fragmentation process has affected the size and connectivity of vegetation formations, which can directly affect the protected areas located in and around the river basin. |

Essa pressão antrópica demanda estudos que avaliem a configuração estrutural do processo de fragmentação no entorno das áreas protegidas. A bacia hidrográfica do rio Tocantinzinho se insere nesse cenário e foi selecionda para avaliação das mudanças na estrutura da paisagem considerando dados históricos de cobertura e uso da terra, para identificar padrões espaço-temporais que possam influir no funcionamento da paisagem. Foram classificadas imagens de satélite (LANDSAT) entre 1985 e 2016, com aplicação de índices descritores da paisagem que, permitiram comparação espacial em sucessão histórica para área da bacia. Os resultados indicam que a substituição das manchas de vegetação nativa por manchas antrópicas impactaram principalmente a formação campestre e que o processo de antropização da área é recente com evidências de desenvolvimento a partir dos anos 2000; verifica-se que as pastagens já estão sendo substituídas pela agricultura e que o processo de fragmentação afetou o tamanho e conectividade das formações vegetacionais, o que pode afetar diretamente as áreas protegidas situadas dentro e no entorno e da bacia hidrográfica.EDUFU - Editora da Universidade Federal de Uberlândia2021-06-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionAvaliado pelos paresapplication/pdfhttps://seer.ufu.br/index.php/caminhosdegeografia/article/view/5518310.14393/RCG228155183Caminhos de Geografia; Vol. 22 No. 81 (2021): Junho; 74-87Caminhos de Geografia; Vol. 22 Núm. 81 (2021): Junho; 74-87Caminhos de Geografia; v. 22 n. 81 (2021): Junho; 74-871678-6343reponame:Caminhos de Geografiainstname:Universidade Federal de Uberlândia (UFU)instacron:UFUporhttps://seer.ufu.br/index.php/caminhosdegeografia/article/view/55183/31697Copyright (c) 2021 Rosane Borges de Oliveira, Karla Maria Silva de Fariainfo:eu-repo/semantics/openAccessde Oliveira, Rosane Borgesde Faria, Karla Maria Silva2021-06-02T16:45:52Zoai:ojs.www.seer.ufu.br:article/55183Revistahttps://seer.ufu.br/index.php/caminhosdegeografia/indexPUBhttp://www.seer.ufu.br/index.php/caminhosdegeografia/oaiflaviasantosgeo@gmail.com1678-63431678-6343opendoar:2021-06-02T16:45:52Caminhos de Geografia - Universidade Federal de Uberlândia (UFU)false |
