Resumo: | This study aimed to assess the wild fire propagation risk to wildfires in the Itacolomi State Park, in Minas Gerais State, Brazil, using GIS and to compare the efficiency of the incident solar radiation over the aspect variable. The following variables were used: land cover/use (LCU), slope (SLP), slope curvature (CUR), aspect (ASP) and incident solar radiation (SOL). The weights of each variable were calculated from the ratio between the total area and the burned area of each class in order to generate the fire propagation risk maps. Fire data from 2016 to 2019 were used for validation. When the moderate risk class was considered susceptible, inadequate precision was observed for both methods (ASP and SOL). On the other hand, when the moderate class was considered non-susceptible to fire, the results presented moderate accuracy. Furthermore, the methods using SOL and ASP showed similar results. The results can guide fire mitigation actions on the park. |

Foram utilizadas as seguintes variáveis: uso / cobertura do solo (LCU), declividade (SLP), curvatura do declive (CUR), aspecto (ASP) e radiação solar incidente (SOL). Os pesos de cada variável foram calculados a partir da razão entre a área total e a área queimada de cada classe, para gerar os mapas de risco de propagação de fogo. Dados de incêndios de 2016 a 2019 foram usados para validação. Quando a classe de risco moderado foi considerada suscetível, a precisão inadequada foi observada para ambos os métodos (ASP e SOL). Por outro lado, quando a classe moderada foi considerada não suscetível ao fogo, os resultados apresentaram acurácia moderada. Além disso, os métodos utilizando o SOL e o ASP apresentaram resultados semelhantes. Os resultados podem nortear as ações de mitigação de incêndios no parque.Embrapa Florestas2023-06-21info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/octet-streamhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/222710.4336/2023.pfb.43e202102227Pesquisa Florestal Brasileira; v. 43 (2023)Pesquisa Florestal Brasileira; Vol. 43 (2023)1983-26051809-3647reponame:Pesquisa Florestal Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAenghttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/2227/1697Copyright (c) 2023 Vicente Paulo Santana Neto, David Marques Soares, Thais Camargos da Silva, Fillipe Tamiozzo Pereira Torreshttps://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccessSantana Neto, Vicente PauloSoares, David MarquesSilva, Thais Camargos daTorres, Fillipe Tamiozzo Pereira2023-03-16T12:47:49Zoai:pfb.cnpf.embrapa.br/pfb:article/2227Revistahttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/PUBhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/oaipfb@embrapa.br || revista.pfb@gmail.com || patricia.mattos@embrapa.br1983-26051809-3647opendoar:2023-03-16T12:47:49Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
