Resumo: Freshwater ecosystems suffer influences by anthropogenic pressures, and they can be represented by land use and cover assessment. The objective of this paper is to evaluate the relations between land use and cover and water quality in a legal protected watershed: Pandeiros River, MG. Water quality assessment was done in 40 sample sites in 3-5th order streams. Trough satellite images, land use and cover was evaluated at three spatial scales: sub-basin, riparian buffer, and local (site). Our results showed that Pandeiros watershed had about 85-95% of natural vegetation at all spatial scales, and water physical and chemical variables are adequate to class 1 of Brazilian environmental law. Correlations between land use and cover class and water quality presented low coefficients at all spatial scales, perhaps due to the low variability of land use and cover results.

O objetivo deste estudo foi avaliar a relação entre o uso e cobertura do solo e a qualidade de água em uma bacia hidrográfica legalmente protegida: a bacia do rio Pandeiros, Minas Gerais. O levantamento de qualidade de água foi realizado em 40 sítios de amostragem balanceada e aleatoriamente distribuídos. Através de imagens de satélite foi avaliado o uso e cobertura do solo em três escalas espaciais: sub-bacia, ripário e local. Os resultados mostraram que a bacia possui em média de 85%-95% de cobertura vegetal íntegra em todas as escalas espaciais avaliadas, e que os parâmetros de qualidade de água estão dentro dos limites de classe 1, segundo a resolução Conama 357/2005. A correlação entre as classes de uso e cobertura do solo e variáveis de qualidade de água foram baixas em todas as escalas avaliadas, e acredita-se que isto deva-se à baixa variabilidade nas porcentagens das classes de uso e cobertura do solo na bacia.UFVJM2017-12-05info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionArtigo avaliado pelos Paresapplication/pdfhttps://revistas.ufvjm.edu.br/revista-espinhaco/article/view/10510.5281/zenodo.3955122Revista Espinhaço ; Revista Espinhaço #112317-0611reponame:Revista Espinhaçoinstname:Universidade Federal dos Vales do Jequitinhonha e Mucuri (UFVJM)instacron:UFVJMporhttps://revistas.ufvjm.edu.br/revista-espinhaco/article/view/105/116Copyright (c) 2022 Revista Espinhaço https://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccessSantos, João Pedro dosMartins, IsabelaCallisto, MarcosMacedo, Diego Rodrigues2022-07-22T18:46:30Zoai:ojs.pkp.sfu.ca:article/105Revistahttps://revistaespinhaco.com/index.php/revista/indexPUBhttps://revistas.ufvjm.edu.br/revista-espinhaco/oairevista.espinhaco@gmail.com || doug.sathler@gmail.com2317-06112317-0611opendoar:2022-07-22T18:46:30Revista Espinhaço - Universidade Federal dos Vales do Jequitinhonha e Mucuri (UFVJM)false
