Resumo
A Fragilidade Ambiental tornou-se uma metodologia assertiva nas propostas de diagnóstico e zoneamento ambiental, nesta pesquisa é usada para analisar a situação da Sub-Bacia Hidrográfica do Ribeirão da Confusão, uma área localizada na UGRHI 21-Peixe. Com o levantamento de dados topográficos, geomorfológicos e pedológicos foi possível identificar os locais que necessitam de conservação ambiental assim como examinar quais áreas tem déficit de vegetação que acabam sendo afetadas por processo erosivos, tudo isso tendo como objeto de análise às Áreas de Preservação Permanente, instrumento vinculado a Lei 12.651/2012 que garante, entre outros locais, a proteção das margens dos rios e nascentes. Por meio dos produtos gerados nos procedimentos metodológicos, sobretudo os mapas sínteses, é possível destacar área carentes de conservação e recuperação. Durante a análise dos resultados outros indicadores contribuíram com a investigação, os relatórios do IPT (2017), do Cadastro Ambiental Rural (2019) e do Inventário Florestal do Estado de São Paulo (IPA, 2020), contribuíram para examinar pontos de suscetibilidade a problemas ambientais dentro da Sub-Bacia, considerando tanto os aspectos das características naturais como as ações antrópicas decorrentes da sua ocupação.

With the survey of topographic, geomorphological and pedological data, it was possible to identify the places that need environmental conservation as well as to examine which areas have a deficit of vegetation that end up being affected by erosive processes, all this having as object of analysis the Permanent Preservation Areas, instrument linked to Law 12.651/2012 that guarantees, among other places, the protection of the banks of rivers and springs. Through the products generated in the methodological procedures, especially the synthesis maps, it is possible to highlight areas in need of conservation and recovery. During the analysis of the results, other indicators contributed to the investigation, the reports from the IPT (2017), the Rural Environmental Registry (2019) and the Forest Inventory of the State of São Paulo (IPA, 2020), contributed to examining points of susceptibility to problems within the Sub-Basin, considering both aspects of natural characteristics and human actions resulting from its occupation.
