Resumo: | Landscape modification and habitat fragmentation have become major research topics. They are considered serious threats to biodiversity. The disturbance history of the area of Jalapão State Park (Parque Estadual do Jalapão – PEJ) was analysed given its characteristic as a Conservation Unit (CU) of integral protection inserted into the Cerrado biome. Thus, the objective of this research is to update the map of land use and cover of this CU and analyse the metrics that quantify habitat connectivity and fragmentation in the landscape ecologyfor 2015 based on the land use map for 2000. In order to plot the PEJ's 2015 map of land use, we used the scene 221/67 (orbit/point) of August 8, 2015, from the Landsat 8 satellite, OLI sensor, since it covered the entire study area and did not present cloud cover. In the digital image processing, radiometric correction, pre-classification, and association of classes of soil use were performed. Subsequently, a supervised classification was performed through visual interpretation. To verify map accuracy, the Kappa coefficient was calculated. Its value was 0.92. From the updated map, calculations of landscape ecology indexes were performed considering area, size, shape, border, and proximity of fragments. The procedures were performed using the software GIS ArcGIS 10.4 and the free extension Patch Analyst 5.2. Based on the maps of land use and cover, and indexes of landscape ecology, it is possible to verify that there were changes in the landscape. As for metrics, it can be concluded that the CU is fragmented (564 fragments) and has a high spatial heterogeneity, a complex form, and an irregular shape due to values of MPS, PSCoV and MSI. |

Considerando o histórico de perturbação da área do Parque Estadual do Jalapão (PEJ), dado sua característica de Unidade de Conservação (UC) de proteção integral inserida no bioma Cerrado, o objetivo desta pesquisa é atualizar o mapa de uso e cobertura do solo dessa UC e analisar as métricas que quantificam a conectividade do habitat e a fragmentação da ecologia da paisagem para o ano de 2015, tendo como base o mapa de uso e ocupação do solo do ano 2000. Para elaborar o mapa de uso do solo do PEJ de 2015, utilizou-se a cena 221/67 (órbita/ponto) de 8 de agosto de 2015 do satélite Landsat 8, sensor OLI, por abranger toda a área de estudo e por não ter cobertura de nuvens. No processamento digital das imagens foram realizadas a correção radiométrica, a pré-classificação e a associação das classes de uso do solo, e, posteriormente, classificação supervisionada por meio de interpretação visual. Para verificar a precisão do mapa foi calculado o coeficiente de Kappa, cujo valor foi de 0,92. A partir do mapa atualizado foram realizados os cálculos de índices de ecologia da paisagem referentes à área, tamanho, forma, borda e proximidade dos fragmentos. Os procedimentos foram realizados no software SIG ArcGIS 10.4 por meio da extensão gratuita Patch Analyst 5.2. Com base nos mapas de uso e cobertura do solo e nos índices de ecologia da paisagem, pode-se constatar que houve mudanças na paisagem. Quanto às métricas, conclui-se que a UC se encontra fragmentada, apresenta 564 fragmentos e possui alta heterogeneidade espacial e forma complexa e irregular em razão dos valores de MPS, PSCoV e MSI.Universidade Federal de Santa Maria2020-09-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/3453910.5902/1980509834539Ciência Florestal; Vol. 30 No. 3 (2020); 755-766Ciência Florestal; v. 30 n. 3 (2020); 755-7661980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/34539/33581Copyright (c) 2020 Ciência Florestalinfo:eu-repo/semantics/openAccessCachoeira, Jader NunesSilva, Allan Deyvid Pereira daBatista, Antonio CarlosBiondi, DanielaGiongo, MarcosGanassoli Neto, Eduardo2020-09-02T20:52:05Zoai:ojs.pkp.sfu.ca:article/34539Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2020-09-02T20:52:05Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
