A análise das potencialidades de fragilidades ambientais de ambientes naturais e antropizados tem como finalidade adequar medidas de conservação, restauração e usos antrópicos destes ecossistemas, mantendo a perpetuação dos recursos naturais. Nessa perspectiva, o presente trabalho buscou identificar os diferentes níveis de fragilidade física na bacia hidrográfica do Rio Mocajuba – PA por meio da interação de elementos físicos e bióticos (pedologia, geologia, altitude, intensidade pluviométrica e uso e cobertura da terra) para a representação da paisagem local. Verificou-se que a bacia do Rio Mocajuba possui uma maior proporção de classes Média, Baixa e Alta, respectivamente, para Fragilidade Emergente e Potencial. Em que as áreas antropizadas promoveram o incremento da fragilidade natural, assim como observou-se que a classe de fragilidade baixa se concentrou na foz da bacia, englobando manguezais e áreas vegetadas. E a classe média e alta envolveram áreas de mangue e áreas antropizadas. Dessa forma a aplicação de metodologias de fragilidade possibilitam gerar um diagnóstico dos fatores limitantes ao uso e ocupação das terras. Assim como identificar áreas prioritárias para conservação e restauração florestal, contribuindo com a gestão e planejamento territorial da bacia.Palavras-chave: Fragilidade. Ecossistema. Alteração.

Potential and emerging environmental fragility of the Mocajuba river basin - PA A B S T R A C TThe analysis of the potential of environmental fragilities of natural and anthropized environments aims to adapt measures for conservation, restoration and anthropic uses of these ecosystems, maintaining the perpetuation of natural resources. In this perspective, the present work sought to identify the different levels of physical fragility in the hydrographic basin of the Mocajuba River - PA through the interaction of physical and biotic elements (pedology, geology, altitude, rainfall and land use and coverage) for representation of the local landscape. It was found that the Mocajuba River basin has a higher proportion of Middle, Low and High classes, respectively, for Emerging and Potential Fragility. Where the anthropized areas promoted an increase in natural fragility, just as it was observed that the class of low fragility was concentrated at the mouth of the basin, encompassing mangroves and vegetated areas. And the middle and upper class involved mangrove areas and man-made areas. Thus, the application of fragility methodologies makes it possible to generate a diagnosis of the factors limiting the use and occupation of land. As well as identifying priority areas for forest conservation and restoration. Contributing to the management and territorial planning of the basin.Keywords: Fragility. Ecosystem. Amendment.
