Resumo: | The Geoprocessing has been considered a fundamental tool in the definition of intervention policies and environmental management. This work presents a methodological guide of application of Geoprocessing technologies to characterize the environmental fragility of Arroio Cadena sub river basin, inserted in the municipality of Santa Maria, central region of Rio Grande do Sul state. We used the methodology proposed by Ross in (1994), which is based in the comprehension of the characteristics and the dynamics of the natural environment. To evaluate the fragility, it is established weights or grades to each situation that the variables can present. We used as indicators of the potential environmental fragility, the factors: declivity and soil type, and as indicators of emerging fragility, the factors: declivity, soil type and the use and occupation of the land. Among the uses of the basin, the areas of soil that is exposed and urbanization predominate. The basin has a weak potential fragility, with 52.9% in relation to the total area, and it is a consequence of the flat declivity aggregated in the soil type. It presents a strong emerging fragility, with 37.7% of the total area, due to the irregular occupations and the inadequate use of natural resources. |

O presente trabalho objetiva caracterizar a fragilidade ambiental da sub-bacia hidrográfica do arroio Cadena, inserida no município de Santa Maria, região central do estado do Rio Grande do Sul, com o uso de geotecnologias. Utilizou-se o método adaptado proposto por Ross em (1994), que é baseado na compreensão das características e da dinâmica do ambiente natural. Para avaliar a fragilidade foram estabelecidos pesos ou notas a cada situação que as variáveis do processo apresentaram, processadas em ambiente SIG a partir da ferramenta álgebra de mapas. A bacia hidrográfica possui uma fragilidade potencial fraca, com 52,9 % em relação a área total, consequência da declividade plana agregada ao tipo de solo. Apresenta uma fragilidade emergente forte, com 37,7% da área total, devido ao processo de urbanização associado a ocupações irregulares e uso inadequado dos recursos naturais. A metodologia apresentada foi considerada satisfatória, pois, foi possível analisar a fragilidade ambiental da área de estudo, e ainda, os resultados obtidos indicam a importância de se implantar um plano de gerenciamento urbano e ambiental no município de Santa Maria.Universidade Federal de Santa Maria2016-02-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/reget/article/view/1998110.5902/2236117019981Revista Eletrônica em Gestão, Educação e Tecnologia Ambiental; REGET, V. 20, N. 1, JAN.-APR., 2016; 464-474Revista Eletrônica em Gestão, Educação e Tecnologia Ambiental; REGET, V. 20, N. 1, JAN.-ABR., 2016; 464-4742236-11702236-1170reponame:Revista Eletrônica em Gestão Educação e Tecnologia Ambiental (REGET)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/reget/article/view/19981/pdfSchiavo, Bruna Nascimento de VasconcellosHentz, Ângela Maria KleinCorte, Ana Paula DallaSanquetta, Carlos Robertoinfo:eu-repo/semantics/openAccess2020-05-19T12:50:03Zoai:ojs.pkp.sfu.ca:article/19981Revistahttps://periodicos.ufsm.br/regetPUBhttps://periodicos.ufsm.br/reget/oaimarcelobdarosa@gmail.com||reget.ufsm@gmail.com2236-11702236-1170opendoar:2020-05-19T12:50:03Revista Eletrônica em Gestão Educação e Tecnologia Ambiental (REGET) - Universidade Federal de Santa Maria (UFSM)false |
