Resumo: The techniques of remote sensing and GIS in environmental characterization and the study of landscape ecology in the Apeu river basin were used with the intention to generate subsidies for the implementation of public policies directed to environmental planning with biodiversity conservation. In 2008, a map of land cover and land use was generated through TM/Landsat 5 digital images; subsequently, the analysis of the fragmentation of trees species populations was performed by landscape metrics. The landscape of the Apeu river basin is strongly marked by cattle ranching and the natural vegetation covers 34.4% of the basin area. This vegetation is highly fragmented and most of it is located next to water resources. In the landscape of the Apeu river basin, 70% of the natural vegetation consists of edge environment, which risks the sustainability of the ecosystem. Thus, the development of efficient ecological management plans is a way of contributing to the conservation and recovery of the remaining fragments of degraded areas in the region.

As técnicas de sensoriamento remoto e geoprocessamento, a caracterização ambiental e o estudo de ecologia de paisagem na bacia hidrográfica do Rio Apeú foram usados com a perspectiva de produzir subsídios para a implementação de políticas públicas voltadas ao planejamento ambiental, que atenda à conservação da biodiversidade. Utilizaram‐se imagens digitais TM/Landsat 5 do ano de 2008, por meio das quais inicialmente gerou‐se o mapa de cobertura vegetal e uso da terra e, posteriormente, efetuou‐se a análise da fragmentação da vegetação arbórea mediante métricas de paisagem. A paisagem da bacia do Rio Apeú é fortemente marcada pela atividade pecuária e os ecossistemas naturais abrangem 34,4% da área da bacia. Essa vegetação encontra‐se bastante fragmentada e a maior parte dela está localizada junto aos recursos hídricos. Na paisagem da bacia hidrográfica do Rio Apeú, 70% da vegetação natural é constituída de ambiente de borda, o que compromete a sustentabilidade do ecossistema. Dessa forma, a elaboração de planos de manejo ecológicos eficientes constitui uma das formas de contribuição para a conservação dos fragmentos remanescentes e a recuperação das áreas degradadas da região.
