Resumo: | The research aims to map and analyze land use and land cover and forest landscape structure from forest fragments (patches) and landscape metrics in the Uraim river basin, Paragominas-PA. The classification of use and coverage was performed using ENVI v. 5.3 with application of the Maximum Likelihood algorithm (MAXVER). Forest fragments were analyzed using landscape metrics with ArcMap v. 10.5 software. The classification indicated that the most predominant classes in the Uraim basin area were primary forest (27.50%), secondary vegetation (21.46%) and agriculture (17.68%). Mapping of forested areas accounted for 29,504 fragments in the basin. Mapping of forest fragments has shown that most of the remnants of the Uraim basin are composed of very small fragments. Most of the forest remnants of the Uraim basin are composed of very small fragments. Larger fragments had lower edge effect than smaller fragments, however, the shape metrics indicated more irregularity for the larger fragments. In this context, it is noteworthy that the development profile of agricultural activities in the Uraim basin is the key factor for forest fragmentation and the analysis of these fragments contributes as an aid in decision making for better management of the basin, considering the need for ecological corridors. |

A classificação de uso e cobertura foi realizada no software ENVI v. 5.3 com aplicação do algoritmo de Máxima verossimilhança (MAXVER). Já os fragmentos florestais foram analisados a partir de métricas de paisagem, no software ArcMap v. 10.5. A classificação indicou que, as classes com maior predomínio na área da bacia do Uraim eram floresta primária (27,50%), vegetação secundária (21,46%) e agricultura (17,68%). O mapeamento das áreas florestadas contabilizou 29.504 fragmentos na bacia. A maior parte dos remanescentes florestais da bacia do Uraim são compostos por fragmentos muito pequenos. Os fragmentos maiores apresentaram menor efeito de borda em relação aos menores, entretanto, as métricas de forma indicaram irregularidade mais acentuada para os fragmentos com maior área. Nesse contexto, vale ressaltar que o perfil de desenvolvimento de atividades agropecuárias na bacia do Uraim é o fator chave para a fragmentação florestal e a análise desses fragmentos contribui como auxílio na tomada de decisões para melhor gestão da bacia, considerando a necessidade de corredores ecológicos.
