| الوصف: | METODOLOGIA PARA AVALIAÇÃO RÁPIDA DA QUALIDADE AMBIENTAL DE NASCENTES METODOLOGÍA PARA LA EVALUACIÓN RÁPIDA DE LA CALIDAD AMBIENTAL EN NACIENTES ABSTRACT This study has the objective of proposing a methodology for the rapid evaluation of the environmental quality of water springs, in the context of hydrographic basins. For this, 11 water springs of the Bacanga River were assessed. To calculate the Environmental Quality Index, it was adopted the Fuzzy operator, Weighted Mean AHP, which uses the methodology of the Analytical Hierarchy Process (AHP) to address the environmental factors involved in the index. Of the 11 analyzed springs, five were classified in class Very Good, three in class Good, two in class Reasonable and one water spring was classified as class Bad. No spring was framed in Class Very Bad. Therefore, we concluded that the use of fuzzy logic with AHP aid has proven to be effective in the environmental quality classification of springs, as it allows monitoring and subsides for the management of this hydrological component. It was proposed that the water springs framed into classes Reasonable and Bad require mitigation measures for its environmental recovery. Urbanization has been identified as the main degradation agent of the springs studied here. Keywords: Land Use and Land Cover Change; Fuzzy Logic; Analytical Hierarchy Process; Bacanga River. RESUMO O presente estudo tem como objetivo propor uma metodologia simplificada para a avaliação rápida da qualidade ambiental de nascentes, no contexto de bacias hidrográficas. Para isso, foram avaliadas 11 nascentes do Rio Bacanga. Para calcular o Índice de Qualidade Ambiental, adotou-se o operador Fuzzy Média Ponderada AHP, que utiliza a metodologia do Processo Analítico Hierárquico (AHP) para lidar com os fatores ambientais envolvidos no índice. Das 11 nascentes analisadas, cinco foram classificados na classe Muito Boa, três na classe Boa, duas na classe Razoável e uma nascente foi classificada na classe Ruim. Nenhuma nascente foi enquadrada na classe ... |
