RESUMO:    As ações antrópicas sobre os recursos naturais no Brasil revelam que não está havendo cumprimento da legislação, principalmente no que se refere às áreas de preservação permanentes (APPs). O objetivo deste trabalho foi delimitar as APPs e mapear as classes de  uso  e  cobertura  da  terra  presentes  na  bacia  do  rio  Piauitinga,  no  estado  de  Sergipe,  averiguando se há conflitos de uso nas áreas de preservação. A demarcação das classes de uso e cobertura da terra ocorreu de forma manual, mediante a interpretação visual de imagens RapidEye. No mapeamento das APPs, foram utilizadas técnicas de geoprocessamento sobre as informações do relevo e a rede hidrográfica. A principal classe de uso e cobertura da terra mapeada foi a de pastagem (50,39%). Das três classes de APPs identificadas, ao longo dos cursos d’água (3,85%), lagos superficiais (0,80%) e ao redor das nascentes (0,08%), todas apresentaram conflito de uso e cobertura da terra. Pode-se afirmar que não está havendo respeito  aos  limites  de  APPs  na  bacia,  principalmente  em  relação  às  áreas  ao  redor  das  nascentes, revelando, principalmente, conflito com a classe pastagem.

ABSTRACT:    The human action over the natural resources in Brazil shows us that legislation has not been accomplished, mainly when the subject is Permanent Preservation Areas (PPAs). The purpose of this work was to delimit the PPAs and to map the classes of land use and land cover present in the Piauitinga river basin, verifying the existence of land use conflicts in the PPAs. The demarcation of land use and land cover classes occurred manually, through the visual interpretation of images RaddiEye from the 2013 year. The delimitation of the PPAs proceeded  based  on  the  elevation  digital  model  and  hydrographic  network  information.  The main land use and land cover classes mapped were farming culture (18.44%), native vegetation (22.69%) and pasture (53.11%). From the three PPAs classes identified, those through the water course (3.78%), superficial lakes (1.91%) and around the sources (0.07%), all of them presented land use and land cover conflict, being the pasture class the one with higher incidence (44.43%). Observing the current environmental law, it is possible to claim that there is a lack of respect to the PPAs limits on the Piauitinga river, mostly considering the areas around the source, showing a great land use and cover conflict of the use classes.
