Resumo: In this study the regulation service was evaluated provided by the maintenance of the riparian zone for the conservation of water courses in the hydrographic basin of a hydroelectric project. This study aims to identify the variables that contribute the most to the ecosystem service of erosion and siltation control in the hydrographic basin of the Nova Ponte Hydroelectric Power Plant (NPHP), Araguari river basin, MG. Were analyzed types of land use and occupation as well a physical habitat metrics in years of regular average rainfall and one with rainfall. Among these variables, presence of native vegetation at riparian zone and flow characteristics were the most important related to the ecosystem service of erosion and sedimentation control in the two sample periods (2009 and 2013). The results obtained corroborate the importance of the conservation of the riparian zone of headwaters for maintenance of the ecosystem service of erosion and sedimentation control, besides contributing to the maintenance of the water cycle and recharge of aquifers and consequent maintenance of water levels in hydroelectric reservoirs.

O objetivo deste estudo foi identificar as variáveis que contribuem para os serviços ecossistêmicos de controle de erosão e sedimentação na bacia hidrográfica do reservatório da Usina Hidrelétrica (UHE) de Nova Ponte, bacia do rio Araguari, MG. Foram analisados os tipos de uso e cobertura do solo, além de métricas de habitats físicos, em um ano de pluviosidade média regular e em um ano de escassez de chuvas. Dentre as variáveis analisadas, as relacionadas à presença de vegetação ripária e velocidade de fluxo foram as mais importantes relacionadas ao serviço ecossistêmico de controle de erosão e sedimentação nos dois períodos amostrais (2009 e 2013). Os resultados obtidos corroboram a importância da conservação da zona ripária de riachos para manutenção do serviço ecossistêmico de controle de erosão e sedimentação, além de contribuírem para manutenção do ciclo da água e recarga de aquíferos e consequente manutenção dos níveis de água em reservatórios hidrelétricos.UFVJM2018-06-07info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionArtigo avaliado pelos Paresapplication/pdfhttps://revistas.ufvjm.edu.br/revista-espinhaco/article/view/11210.5281/zenodo.3952921Revista Espinhaço ; Revista Espinhaço #122317-0611reponame:Revista Espinhaçoinstname:Universidade Federal dos Vales do Jequitinhonha e Mucuri (UFVJM)instacron:UFVJMporhttps://revistas.ufvjm.edu.br/revista-espinhaco/article/view/112/123Copyright (c) 2022 Revista Espinhaço https://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccessSilveira, Carolina Rezende SavinoMacedo, Diego RodriguesCallisto, Marcos2022-07-22T18:46:54Zoai:ojs.pkp.sfu.ca:article/112Revistahttps://revistaespinhaco.com/index.php/revista/indexPUBhttps://revistas.ufvjm.edu.br/revista-espinhaco/oairevista.espinhaco@gmail.com || doug.sathler@gmail.com2317-06112317-0611opendoar:2022-07-22T18:46:54Revista Espinhaço - Universidade Federal dos Vales do Jequitinhonha e Mucuri (UFVJM)false
