ANÁLISE EMPÍRICA DA FRAGILIDADE AMBIENTAL EM ÁREAS DE EXPANSÃO URBANA: O CASO DO SETOR NOROESTE DO SÍTIO URBANO DE PIRACICABA (SP)
Resumo
Este artigo tem como objetivo discutir a aplicação da proposição
metodológica de Ross (1990, 1994 e 2001), quanto à análise empírica da
fragilidade de ambientes naturais e antropizados em área de expansão
urbana, contribuindo com a elaboração de um diagnóstico ambiental que
propicie subsídios ao planejamento urbano. O procedimento metodológico
promove a elaboração de um produto cartográfico de síntese para análise
integrada da informação geográfica, nomeado por Carta de Fragilidade
Ambiental, que é derivado da compilação de informações adquiridas nos
produtos cartográficos intermediários, como a Carta de Declividade ou
Clinográfica, a Carta Pedológica, a Carta Geomorfológica e a Carta de
Cobertura Vegetal e Uso da Terra. A pesquisa se enquadra nos termos de
uma Geografia Física Aplicada e de uma Geomorfologia Aplicada, no bojo
de uma abordagem geográfica integrada, com o intuito de contribuir com o
planejamento urbano do setor de expansão noroeste do sítio urbano de
Piracicaba (SP). Os resultados obtidos apontam que as ações promovidas
pelo sistema antrópico vêm alterando os fluxos de matéria e energia do
sistema geomorfológico. As principais formas de interferências
antrópicas estão associadas à monocultura canavieira e à expansão urbana
sem planejamento, interferindo diretamente na dinâmica morfológica e
hidrológica do sistema geomorfológico.

Empirical Analysis of Environmental Fragility Areas of Urban Exp
ansion: the Northwest Sector case of The Urban Site of Piracicaba (SP)
This article has as objective to discuss the application of Ross’s methodological proposition (1990, 1994 and 2001), as for the empirical analysis of the fragility of natural and anthropized environments in urban expansion area, contributing to the elaboration on an environmental diagnosis that propitiates subsidy to the urban planning. The methodological procedure promotes the elaboration on a cartographic product of synthesis to analysis of the integrated geographical information, named Environmental Fragility Map, which is derived from the compilation of acquired information in intermediate cartographic products as the Steepness or Clinographic Map, the Pedologic Map, the Geomorphological Map and the Vegetal Cover and Land use Map. The research frames to the terms of an Applied Physical Geography and an Applied Geomorphology, at the bulge of an integrated geographical approach, with the intention of contributing to the urban planning of the northwest expansion sector of the urban site of Piracicaba (SP). The obtained results point that the actions promoted by the anthropic system have been altering the matter and energy flows of the geomorphological system. The main forms of anthropic interference are associated with the sugarcane monoculture and the unplanned urban expansion, directly interfering in the morphological and hydrological dynamics of the geomorphological system.
Key words: Integrated geographical approach. Cartographic products of synthesis. Environmental fragility. Northwest sector of the urban site of Piracicaba.
