Previous issue date: 2018-03-14 / The creation of Conservation Units has been showing the most widespread idea in our current conception of nature conservation, mainly with the various transformations that occurred in the second half of the twentieth century. The Environmental Protection Areas (APA) are an example of Conservation Units, as is the case of APA Serra Branca, a Sustainable Use Conservation Unit. There are several criteria used for the delimitation of a Conservation Unit, and the risk of environmental vulnerability is one of them, so this work aimed to analyze the environmental vulnerability of the APA Serra Branca through environmental indicators for the elaboration of an Environmental Zoning, using variables that point out and quantify vulnerable areas as a means of responding if environmental indicators are capable of measuring environmental vulnerability, making it possible to infer about environmental sustainability and the possible fragilities and potentialities of the area. The application of geoprocessing techniques subsidized the analysis and integration of data and information, as well as the generation of products, such as cartographic. It was these techniques that made it possible to obtain the results such as: Map of Critical Areas; Modeling of the Environmental Vulnerability of the APA Serra Branca and Environmental Zoning of the APA Serra Branca. In order to define the critical areas, the criteria proposed by Bessa Junior and Muller were taken into account, taking into account environmental indicators (Hypsometry, Declivity, Hydrography) that were crossed through the intersection with the land Use and Coverage map. The modeling developed was based on criteria adapted from Crepani to local reality. The map of environmental vulnerability derived from map algebra related to the themes: Land Declivity, Use and Coverage, Geomorphology, Geology and Soils, for each variable, a vulnerability value was inserted through a map reclassification technique. As a final result, the Environmental Zoning was generated, which was derived from the intersection of the Environmental Vulnerability map with the Land Use and Coverage map. At the end of these stages, it was possible to observe the areas with greater environmental vulnerability, and the areas that were more stable, which represented the greater part of the APA Serra Branca area / A cria??o de Unidades de Conserva??o vem se mostrando a ideia mais difundida na nossa atual concep??o de conserva??o da natureza, principalmente com as diversas transforma??es que ocorreram na segunda metade do s?culo XX. As ?reas de Prote??o Ambiental (APA) s?o um exemplo de Unidades de Conserva??o, como ? o caso da APA Serra Branca, uma Unidade de Conserva??o de Uso Sustent?vel. S?o diversos os crit?rios utilizados para a delimita??o de uma Unidade de Conserva??o, e o risco a vulnerabilidade ambiental ? um deles, ent?o esse trabalho objetivou analisar a vulnerabilidade ambiental da APA Serra Branca atrav?s de indicadores ambientais para a elabora??o de um Zoneamento Ambiental, utilizando vari?veis que apontem e quantifiquem ?reas vulner?veis, como meio de responder se os indicadores ambientais s?o capazes de mensurar a vulnerabilidade ambiental, possibilitando inferir sobre a sustentabilidade ambiental e as poss?veis fragilidades e potencialidades da ?rea. A aplica??o de t?cnicas de geoprocessamento subsidiou a an?lise e integra??o de dados e informa??es, bem como a gera??o de produtos, como os cartogr?ficos. Foram essas t?cnicas que tornaram poss?vel a obten??o dos resultados tais como: Mapa de ?reas Cr?ticas; Modelagem da Vulnerabilidade Ambiental da APA Serra Branca e Zoneamento Ambiental da APA Serra Branca. Para definir as ?reas cr?ticas, foram seguidos crit?rios propostos por Bessa Junior e Muller, levando em considera??o, indicadores ambientais (Hipsometria, Declividade, Hidrografia) que foram cruzados atrav?s da interse??o com o mapa de Uso e Cobertura das Terras. A modelagem desenvolvida foi baseada nos crit?rios adaptados de Crepani ? realidade local. O mapa de vulnerabilidade ambiental derivou da ?lgebra de mapas relacionada aos temas: Declividade, Uso e Cobertura das Terras, Geomorfologia, Geologia e Solos, para cada vari?vel, foi inserido um valor de vulnerabilidade por meio de t?cnica de reclassifica??o de mapas. Como resultado final, foi gerado o Zoneamento Ambiental, que foi derivado da interse??o do mapa de Vulnerabilidade Ambiental com o mapa de Uso e Cobertura das Terras. Ao fim dessas etapas, foi poss?vel observar as ?reas com maior vulnerabilidade ambiental, e as ?reas que se encontravam com uma maior estabilidade, que representavam a maior parte da ?rea da APA Serra Branca
