Resumo

Objetivou-se analisar o conflito de uso e cobertura das terras em Áreas de Preservação Permanente (APP) do Ifes – Campus de Alegre, à luz do atual Código Florestal Brasileiro. Foram delimitadas e investigadas as APP de nascentes, cursos d’água, declividades e topos de morro. As APP de declividades e de topos de morro foram obtidas a partir do modelo digital de elevação global GEDM-ASTER. O uso e a cobertura da terra foram alcançados por fotointerpretação sobre imagem orbital do sensor Geoeye 1 (resolução espacial de 0,50 m), totalizando 36 classes temáticas. Os resultados revelam que as APP totalizam 34,33% da área do Ifes – Campus de Alegre, ocupando 114,32 ha de extensão. As APP de topos de morro e dos cursos d’água são as que ocupam maior área, correspondendo a 16,94% e 14,03%, respectivamente. As APP de cursos d’água são as mais atingidas e as principais classes responsáveis por conflitos são as pastagens naturais (20,41 ha) e as estradas não pavimentadas (1,18 ha).

Abstract

This study aimed to analyze the conflict of land use and land cover in Permanent Preservation Areas (PPA) of the ‘Instituto Federal de Educação, Ciência e Tecnologia do Espírito Santo’ - Ifes, Alegre Campus, in light of the current Brazilian Forest Code. The springs, watercourses, slopes and hill tops of the PPA were defined and investigated. The slopes and hill tops were obtained by the global digital elevation model GEDM-ASTER. Land use and land cover were achieved by photo-interpretation of orbital image sensor Geoeye 1 (spatial resolution of 0.50 m), totaling 36 thematic classes. The results showed that the PPAs occupy 34.33% of the total Ifes area, with an extension of 114.32 ha. The hilltops and watercourses occupy the largest areas, corresponding to 16.94% and 14.03%, respectively. The watercourses are the most affected areas, and the main classes responsible for conflicts are natural pastures (20.41 ha) and non-paved roads (1.18 ha).
