Resumo: | Environmental indices are important information tools about the state of the soil resulting from the use and anthropic management that impacts positively or negatively the quality of life in living beings. The objective of this study was to elaborate aSoil and Environmental Status Index (SESI) to analyze the spatialization through interpolation by ordinary kriging of soil chemical factors resulting from anthropic use and management in the Una River Watershed. Thus, it is possible to observe that there is a phosphorus deficit in the Una River Watershed and that the transport of this nutrient to the water bodies can trigger eutrophication processes. Approximately 65% of the area of the Una River Watershed is classified as regular, that is, they are in the range of 0.38 to 0.60. There were no values classified as bad or awful for the SESI, indicating that the Watershed is poorly degraded, a fact evidenced by the occupation rate by forests in the study area that corresponds to 41% of the territorial extension. The SESI can be used asan important tool for the management of soil state in watersheds, since it allows the interpretation of this state numerically, and can serve as a decision-making tool for public and private managers. |

Nesse estudo objetivou-se elaborar um índice do Estado Ambiental do Solo (IEAS) para analisar a espacialização através da interpolação por krigagem ordinária de fatores químicos do solo resultante do uso e manejo antrópico na Bacia Hidrográfica do Rio Una. Como resultado, é possível observar que há um déficit de fósforo na Bacia Hidrográfica do Rio Una e que o carreamento desse nutriente para os corpos de água pode desencadear processos de eutrofização. Aproximadamente 65% da área da Bacia Hidrográfica do Rio Una está classificada como regular, isto é, encontram-se na faixa de 0,38 a 0,60. Não houve valores classificados como ruins ou péssimos para o IEAS, indicando que a Bacia Hidrográfica está pouco degradada, fato comprovado pela taxa de ocupação por matas na área de estudo que corresponde a 41% de sua extensão territorial. O IEAS é uma importante ferramenta para a gestão do estado do solo em bacias hidrográficas, pois permite interpretar numericamente esse estado, além de poder servir como um instrumento de tomada de decisão para gestores públicos e privados.Universidade Federal de Uberlândia2018-12-20info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.ufu.br/index.php/sociedadenatureza/article/view/3734010.14393/SN-v30n3-2018-5Sociedade & Natureza; Vol. 30 No. 3 (2018); 85-107Sociedade & Natureza; v. 30 n. 3 (2018); 85-1071982-45130103-1570reponame:Sociedade & natureza (Online)instname:Universidade Federal de Uberlândia (UFU)instacron:UFUporhttps://seer.ufu.br/index.php/sociedadenatureza/article/view/37340/pdfCopyright (c) 2018 Revista Sociedade & Naturezainfo:eu-repo/semantics/openAccessSilva, Darllan Collins da Cunha eAlbuquerque Filho, José LuizOliveira, Renan Angrizani deLourenço, Roberto Wagner2020-07-03T10:37:31Zoai:ojs.www.seer.ufu.br:article/37340Revistahttp://www.sociedadenatureza.ig.ufu.br/PUBhttps://seer.ufu.br/index.php/sociedadenatureza/oai||sociedade.natureza.ufu@gmail.com|| lucianamelo@ufu.br1982-45130103-1570opendoar:2020-07-03T10:37:31Sociedade & natureza (Online) - Universidade Federal de Uberlândia (UFU)false |
