Resumo: | In this study, we discuss the importance of land use, land cover planning and forest stand management in fire hazard reduction, through the analysis of fire behavior in relation to landscape changes in Deilão, northeastern Portugal. Markov chains and cellular automata model were used to project future landscapes whose structures were quantified by landscape metrics. FlamMap model was used to simulate fire behavior. According to landscape metrics from Fragstats, we observe that scenarios and projections in Deilão have a trend towards landscape simplification, which may facilitate the occurrence of larger, more severe fires. The analyses indicate an increased fire hazard trend in the region, largely caused by the continuity of forest cover. To avoid such impacts, forest management and landscape development should be modified in order to reduce the accumulation of combustible materials. |

Foram utilizadas cadeias de Markov e modelos de autômatos celulares como metodologia para projetar a paisagem no futuro. FlamMap foi utilizado para simular o comportamento do fogo. De acordo com as métricas da paisagem obtidas no Fragstats, observou-se que os cenários e projeções em Deilão têm uma tendência à simplificação da paisagem, o que pode facilitar a ocorrência de incêndios maiores e mais graves. A análise dos resultados indicou uma tendência ao aumento do perigo de incêndios na região, em grande parte, ocasionado pela expansão de plantações contínuas de florestas. Para evitar tais impactos, o manejo florestal e ordenamento da paisagem devem ser modificados a fim de se reduzir o acúmulo de materiais combustíveis.Universidade Federal de Santa Maria2017-06-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/2772810.5902/1980509827728Ciência Florestal; Vol. 27 No. 2 (2017); 457-469Ciência Florestal; v. 27 n. 2 (2017); 457-4691980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/27728/15735Copyright (c) 2017 Ciência Florestalinfo:eu-repo/semantics/openAccessde Magalhães, Simone RodriguesRibeiro, Carlos Antonio Alvares Soaresde Azevedo, João Carlos MartinsFerreira, José Manuel Correia dos SantosFernandes, Paulo Alexandre Martinsda Silva, Carlos Alberto Rodrigues LoureiroPinheiro, Helena Margarida Pires2017-07-08T02:12:01Zoai:ojs.pkp.sfu.ca:article/27728Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-07-08T02:12:01Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
