Resumen
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.
