Resumo: Geographic Information System tools, combined with mathematical methods for complex geospatial scientific investigations, are essential for environmental zoning. Among these tools, environmental fragility models evaluate criteria related to the physical attributes of the landscape to ensure multi-disciplinarity of the information plans used in a study. However, questions are raised on the priority allotted to each criterion or environmental factor within a multi-criteria analysis model. In this sense, the analytic hierarchy process is another mathematical model that is used in decision theory, which sorts criteria hierarchically. This study aims to use the AHP method as a tool to support multi-criteria decision making as applied to environmental fragility mapping, using the Jequitinhonha River Basin, Minas Gerais, Brazil, as a case study. The application of the AHP method provided a hierarchy of five important environmental criteria for the environmental fragility mapping. The use of AHP allowed the modeling of empirical evaluations in mathematically consistent results, to provide better conciseness in geospatial processes. Therefore, it is an adequate method to minimize subjectivity in environmental and territorial planning. It can also help the management of priority zones for conservation, preservation, or ecological restoration.

As ferramentas do Sistema de Informações Geográficas, combinadas com métodos matemáticos para investigações científicas geoespaciais complexas, são essenciais para o zoneamento ambiental. Dentre essas ferramentas, os modelos de fragilidade ambiental avaliam critérios relacionados aos atributos físicos da paisagem para garantir a multidisciplinaridade dos planos de informações utilizados em um estudo. No entanto, são levantadas questões sobre a prioridade atribuída a cada critério ou fator ambiental dentro de um modelo de análise de múltiplos critérios. Nesse sentido, o processo analítico hierárquico é outro modelo matemático usado na teoria da decisão, que classifica os critérios hierarquicamente. Este estudo tem como objetivo utilizar o método AHP como uma ferramenta para apoiar a tomada de decisão multicritério aplicada ao mapeamento de fragilidade ambiental, usando a Bacia Hidrográfica do rio Jequitinhonha, Minas Gerais, Brasil, como um estudo de caso. A aplicação do método AHP forneceu uma hierarquia de cinco critérios ambientais importantes para o mapeamento da fragilidade ambiental. O uso do AHP permitiu modelar avaliações empíricas em resultados matematicamente consistentes, para proporcionar uma melhor concisão nos processos geoespaciais. Portanto, é um método adequado para minimizar a subjetividade no planejamento ambiental e territorial. Também pode ajudar no gerenciamento de zonas prioritárias para conservação, preservação ou restauração ecológica.Universidade Federal do Paraná2020-09-04T17:20:17Z2020-09-04T17:20:17Z2020-07info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfFRANÇA, L.
