Abstract


This paper presents an environmental transgression analysis based on the 1965 Forest Code and its amendments in Permanent Preservation areas and Legal Forest reserves in the Queima-Pé river basin. We used images from GeoEye with 3m of spatial resolution to identify anthropogenic and natural vegetation areas and to determine the Permanent Preservation areas, supported by a geographic information system. The buffers for the Permanent Preservation areas were automatically generated in a geographic information system considering the sources, drainage network, and artificial reservoirs and then were compared with a map of human activities and natural vegetation. The results demonstrated that in the region of phytoecological forest, the vegetation comprised 7.18% of the Legal Forest reserves and the Savanna (Cerrado) and natural vegetation comprised 7.82% of the Legal Forest reserves. Approximately 64.10% of the permanent preservation areas were occupied by riparian vegetation. Generally, the basin presents an environmental passive of 8009.81 hectares.
