Resumo: | The forest remnants present a relevant multi-functionality for the provision of ecosystem services to cities, especially the ones related to water availability in quantitative and qualitative terms, since they contribute to the control of runoff and floods, reduction of water filtration pollution, among others. Therefore, the present study aimed to assess the environmental quality of the forest remnants of the Capivari River sub-basin, in Campinas-SP, which has high water potential, by using landscape metrics. The analyzes were performed in ArcGIS on the following metrics: AREA, CAI, CI, ENN, PROXFLOW, WAT, SUR, EROD, applied for the calculation of the Environmental Quality Index (IQrem). It was identified that 78.0% of remnants have medium environmental quality, followed by 15.2% with low quality and only 6.8% with high quality. This condition is mainly related to the predominance of remnants with little or no central area, associated with predominantly elongated shapes and the distribution of these remnants in a predominantly anthropized mesh. On the other hand, these remnants have considerable connectivity, since more than 50% are close to a neighboring remnant within 60 m. A key point identified is the fact that 93.2% of the remnants are distant up to 60 m from some watercourse. Thus, it was found that the forest remnants play a significant role in maintaining water availability for the municipality of Campinas, in terms of quality and quantity. This increases the importance of carrying out effective management actions that contribute to increasing and ensuring the environmental quality of these remnants. |

Diante disso, o presente estudo teve como objetivo avaliar a qualidade ambiental dos remanescentes florestais da sub-bacia do rio Capivari, em Campinas-SP, que apresenta alto potencial hídrico, utilizando-se métricas da paisagem. As análises foram realizadas em ArcGIS sobre as seguintes métricas: AREA, CAI, IC, ENN, PROXRIOS, AGUA, BORDA, EROD, aplicadas para o cálculo do Índice de Qualidade Ambiental (IQrem). Identificou-se que 78,0% dos remanescentes apresentam qualidade ambiental média, seguidos por 15,2% com qualidade baixa e apenas 6,8% com qualidade alta. Esta condição está principalmente relacionada à predominância de remanescentes com pouca ou nenhuma área central, associada à formatos predominantemente alongados e a distribuição destes remanescentes em uma malha predominantemente antropizada. Por outro lado, estes remanescentes apresentam considerável conectividade, já que mais de 50% estão próximos a algum remanescente vizinho em até 60 m. Um ponto chave identificado é o fato de que 93,2% dos remanescentes estão em até 60m de algum curso d’água. Desta forma, constatou-se que os remanescentes florestais apresentam uma significativa função para a manutenção da disponibilidade hídrica para o município de Campinas, em termos de qualidade e quantidade. Isto aumenta a importância de que sejam realizadas ações de manejo eficazes que contribuam para aumentar e assegurar a qualidade ambiental destes remanescentes.Universidade Federal de Uberlândia2021-07-09info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/pdfhttps://seer.ufu.br/index.php/sociedadenatureza/article/view/5912910.14393/SN-v33-2021-59129Sociedade & Natureza; Vol. 33 (2021)Sociedade & Natureza; v. 33 (2021)1982-45130103-1570reponame:Sociedade & natureza (Online)instname:Universidade Federal de Uberlândia (UFU)instacron:UFUporenghttps://seer.ufu.br/index.php/sociedadenatureza/article/view/59129/32235https://seer.ufu.br/index.php/sociedadenatureza/article/view/59129/32236Copyright (c) 2021 Alessandra Leite da Silva, Admilson Írio Ribeiro, Regina Márcia Longoinfo:eu-repo/semantics/openAccessSilva, Alessandra Leite daRibeiro, Admilson ÍrioLongo, Regina Márcia2021-07-28T18:28:11Zoai:ojs.www.seer.ufu.br:article/59129Revistahttp://www.sociedadenatureza.ig.ufu.br/PUBhttps://seer.ufu.br/index.php/sociedadenatureza/oai||sociedade.natureza.ufu@gmail.com|| lucianamelo@ufu.br1982-45130103-1570opendoar:2021-07-28T18:28:11Sociedade & natureza (Online) - Universidade Federal de Uberlândia (UFU)false |
