GEOPROCESSING APPLIED IN THE DETERMINATION OF THE SOIL USE IN PERMANENT PRESERVATION AREAS, ACCORDING TO BRAZILIAN ENVIRONMENTAL LEGISLATION

Abstract

The work sought to obtain the conflict spatial of soil use in permanent preservation areas in River Capivara - Botucatu (SP). The cartographic bases were: the chart planialtimetric of Botucatu used in the georreferencing and the satellite image of 2010. The GIS-IDRISI was used for conversion of the analogical information for digital and determination of the areas. The soil use showed that the pastures occupy most of the area (31,56%) showing with that the predominance of low fertility soils, besides the prevalence of the regional farming. The satellite image allowed the mapping of the soil use in a reliable way, as well as they will be for regional plannings futures. The area is being conserved environmentally, because it comes covered with more than 20% of forests (30,62%), minimum demanded by the Brazilian Forest Code effective. The delimitation of the drainage net, of PPA's and of use conflict in PPAs showed that only 29,2% are being busy appropriately for forests and 2 inadequately 59,98% for pastures and 29,68% for reforestations.
