he enactment of the current Forest Code (Law 12.651/12) raised concerns regarding the preservation and protection of natural resources in different biomes of Brazil, due to its very general nature and tolerance to abusive uses. Facing to this question, this article is presented applied and comparative study of the use restrictions on private properties as the current Forest Code and the environmental zoning drawn from the proposal Geoecology of the landscape, applied in the high basin of Areia Dourada, Marabá Paulista (SP). Thus, we intend to evaluate the spatial differences in restricting land use identified in accordance with Law 12.651/12 and to a study conducted using the methodology of Geoecology, which is characterized by integrating the various elements that make up the natural landscape. Still, were added to the analysis linear erosional features in order to compare the fragile nature of the basin with the consequences of inadvertent use. As a result, the current Forest Code contemplates only 6,28% (290,55 ha) of the watershed area, which tends to aggravate erosive problematic as the methodology of Geoecology points to the need for preservation of 51,66% (2.388,28 ha). This land is directly affect by the areas of erosion in ravines and gullies, indicating efficiently the natural fragility of the basin.
