Resumo: The expansion of the urban area of Matola city in Mozambique has happened according an unstructured way. For better understand that expansion along the time images from TM / Landsat 5 and OLI / Landsat 8 orbital sensor from 1997, 2007 and 2014 were utilized in order to produce temporal vegetation cover maps. From these maps it was estimated the Vegetation Cover Index (VCI) that was useful to evaluate the urban sprawl. Results indicated that the area of vegetation cover decreased to 118.74km 2 (52.62%) in 17 years and the VCI also decreased from 61.25% in 1997 to 29.02% in 2014. On the other hand, the detailed study of the VCI to different neighborhoods of Matola, showed a very uneven spatial distribution, and from this distribution, there are alarming situations in certain villages of the Administrative Post of Matola-Sede, for the year 2014, being Matola H, Matola B, Matola G, Sikwama and Liberdade with values lower than 5%, what suggests these villages as floristic deserts.

Para melhor diagnosticar essa expansão ao longo do tempo, foram empregadas imagens dos sensores orbitais TM/Landsat 5 e OLI/Landsat 8, dos anos 1997, 2007 e 2014. A extração de informação dessas imagens foi feita mediante o emprego de técnicas de processamento de imagens com o objetivo de mapear a cobertura vegetal do município ao longo do tempo. A partir desses mapeamentos foram estimados índices de cobertura vegetal (ICV) que serviram de base para avaliar a expansão urbana. Os resultados indicaram que a área da cobertura vegetal do Município reduziu 118,74m2 (52,62%) em 17 anos, fazendo com que o ICV reduzisse de 61,25% em 1997 para 29,02% em 2014. Por outro lado, o estudo detalhado do ICV por bairros, mostrou distribuição espacial bastante desigual e dessa distribuição, percebem-se situações alarmantes em certos bairros do Posto Administrativo da Matola-Sede, para o ano de 2014, como Matola H, Matola B, Matola G, Sikwama e Liberdade com valores muito abaixo dos 5%, considerando-se esses bairros desertos florísticos.Universidade Federal de Uberlândia2018-04-12info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.ufu.br/index.php/sociedadenatureza/article/view/3873910.14393/SN-v29n3-2017-1Sociedade & Natureza; Vol. 29 No. 3 (2017); 371-381Sociedade & Natureza; v. 29 n. 3 (2017); 371-3811982-45130103-1570reponame:Sociedade & natureza (Online)instname:Universidade Federal de Uberlândia (UFU)instacron:UFUporhttps://seer.ufu.br/index.php/sociedadenatureza/article/view/38739/pdf_1Copyright (c) 2018 Revista Sociedade & Naturezainfo:eu-repo/semantics/openAccessMatule, Euclides DélioPonzoni, Flávio JorgeChaves, Joselisa Maria2021-04-30T13:55:17Zoai:ojs.www.seer.ufu.br:article/38739Revistahttp://www.sociedadenatureza.ig.ufu.br/PUBhttps://seer.ufu.br/index.php/sociedadenatureza/oai||sociedade.natureza.ufu@gmail.com|| lucianamelo@ufu.br1982-45130103-1570opendoar:2021-04-30T13:55:17Sociedade & natureza (Online) - Universidade Federal de Uberlândia (UFU)false
