Mapeamento de areas de preservação permamente na carta Sb-22-X-D-1 na escala de 1:50.000 e identificação do uso do solo

Abstract

Permanent Preservation Areas (APP’s) have been defined and established by the Brazilian Forest Code, and created to protect natural environment, which means, they are not suitable areas for land use alteration, and should be covered with existent original vegetation. This paper aims to delimitation provided APP’s in Law (Forest Code Brazilian – Law 12.651/2012 – and CONAMA Resolution 303/2002) and its classification related to use of land, according to Earth Class 2010, provided by INPE, in 1: 50.000 scale, supported in computational techniques tools of geoprocessing and remote sensing products. Soil use, was classified as pasture, forest, secondary forest, urban area, non-forest. Mapping identified that 47454.06 ha from 305,369.03 total ha from studied area, are characterized as permanent preservation areas, corresponding to 15.78% of the total area of the chart. Registered PPA’s were the drains (95.2%), springs (0.8%), lakes (4.0%). In relation to soil use in areas that should be APP’s, but having other use and occupation, it means that, areas with occupancy conflict with environmental regulations, pasture corresponded to 32.18% and secondary vegetation 8.94% of all PPA’s. Use of geographic information system was effective in the realized analyzes, endorsing to future decision-making for efficiency in soil use and agreement with current legislation.
