Resumo: | This study aimed at surveying the physiography and land use in the small watershed of Lençóis River, in order to constitute an instrument for the management of natural resources. This small watershed is located in the municipality of Lençóis, Chapada Diamantina, state of Bahia, Brazilian Northeast. The waters drained by this small watershed are destined to the water supply of the city. The methodology used they based on geosystemic theories and methods and on the use of geoprocessing and remote sensing. The results indicated that the small watershed of Lençóis River is elongated, with a low branched and sparse hydrography. The climatic typology is tropical at altitude, and lithology is predominantly metasedimentary, with a structural geology defined by transcurrent fault, which controls the main fluvial channel. Sierras, valleys and river terraces, with an average slope of 27.5%, compose the geomorphology. The predominant vegetation cover class is the rupestrian fields. The levels of preservation of the vegetation cover, detected in the mapping, provide ensure of protection to the fluvial system, thus protecting the good natural condition of the predominant geoenvironmental units. At the geosystemic interface, the small watershed Lençóis River presents physical-environmental characteristics that suggest a management that values conservation, in order to ensure the balanced use of natural resources that promote socio-economic resources. |

Esta microbacia, localiza-se no município de Lençóis, Chapada Diamantina, estado da Bahia, Região Nordeste do Brasil. As águas drenadas por esta microbacia são destinadas ao abastecimento hídrico da cidade. A metodologia empregada se fundamentou em teorias e métodos geossistêmicos e no uso do geoprocessamento e sensoriamento remoto. Os resultados indicaram que a microbacia do Rio Lençóis é alongada, com uma hidrografia pouco ramificada e esparsa. A tipologia climática é tropical de altitude, e a litologia é predominantemente metassedimentar, com uma geologia estrutural enviesada por falha transcorrente, que controla o canal fluvial principal. A geomorfologia é composta por serras, vales e terraços fluviais, com declividade média de 27,5%. A classe de cobertura vegetal predominante é o campo rupestre. Os níveis de preservação da cobertura vegetal, detectados no mapeamento, fornecem garantias de proteção ao sistema fluvial, resguardando assim, a boa condição natural das unidades geoambientais predominantes. Na interface geossistêmica, a microbacia do Rio Lençóis apresenta características físico-ambientais que sugerem um gerenciamento direcionado para conservação, a fim de garantir o uso equilibrado dos recursos naturais que promova recursos socioeconômicos.Universidade Federal de Uberlândia2017-05-18info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.ufu.br/index.php/sociedadenatureza/article/view/3047110.14393/SN-v29n1-2017-6Sociedade & Natureza; Vol. 29 No. 1 (2017)Sociedade & Natureza; v. 29 n. 1 (2017)1982-45130103-1570reponame:Sociedade & natureza (Online)instname:Universidade Federal de Uberlândia (UFU)instacron:UFUporhttps://seer.ufu.br/index.php/sociedadenatureza/article/view/30471/pdfMattos, Jonatas BatistaDe Paula, Francisco Carlos Fernandesinfo:eu-repo/semantics/openAccess2021-04-30T13:56:41Zoai:ojs.www.seer.ufu.br:article/30471Revistahttp://www.sociedadenatureza.ig.ufu.br/PUBhttps://seer.ufu.br/index.php/sociedadenatureza/oai||sociedade.natureza.ufu@gmail.com|| lucianamelo@ufu.br1982-45130103-1570opendoar:2021-04-30T13:56:41Sociedade & natureza (Online) - Universidade Federal de Uberlândia (UFU)false |
