Resumo: | The GIS (Geographical Information Systems), as a tool for theenvironmental analyses of specific modules, makes possiblethe use of different sources of information simultaneously. Inorder to exploit this characteristic, the present research applieda Multi criteria evaluation (MCE), using also the AHP (AnalyticHierarchy Process) for the identification of differentiated levelsof environmental fragility from the definition of weights for theconsidered physical variables. The work has used the Cará-Cará River watershed, Ponta Grossa/PR, as its study area.The results have shown a five-class variation of environmentalfragility, which have been correlated witch the reality, givingsupport to a positive evaluation of the methods which wereused. |

O trabalho utilizou a bacia hidrográfica dorio Cará-Cará, Ponta Grossa/PR, como área de estudo. Osresultados demonstraram uma variação de cinco classes defragilidade ambiental que se correlacionaram com a realidade,fornecendo assim subsídios para uma avaliação positiva dosmétodos utilizados.UFPRcapesMiara, Marcos AntonioOka-Fiori, Chisato2007-06-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://revistas.ufpr.br/raega/article/view/664210.5380/raega.v13i0.6642RA'E GA Journal - The Geographic Space in Analysis; v. 13 (2007)RAEGA - O Espaço Geográfico em Análise; v. 13 (2007)2177-27381516-413610.5380/raega.v13i0reponame:Ra'e Ga (Online)instname:Universidade Federal do Paraná (UFPR)instacron:UFPRporhttps://revistas.ufpr.br/raega/article/view/6642/9084info:eu-repo/semantics/openAccess2018-10-03T13:14:41Zoai:revistas.ufpr.br:article/6642Revistahttps://revistas.ufpr.br/raegaPUBhttps://revistas.ufpr.br/raega/oai||raega@ufpr.br2177-27382177-2738opendoar:2018-10-03T13:14:41Ra'e Ga (Online) - Universidade Federal do Paraná (UFPR)false |
