Descrição
This research realizes the application of the model, proposed by Jansen (2013), in the landscape in the contact between the Rio das Velhas Plain and the western edge of the Southern Espinhaço Ridge. This area is a representative sample of wide geo-ecological diversity due to its location. The research was based on the concepts of landscape and geosystems of Bertrand (2004), guiding field work of Couto and Travassos (2016), and allowed the model’s application of natural and environmental vulnerabilities. From west to east, from the municipality of Corinto to Diamantina, there is the Rio das Velhas Plain, the Karst of Monjolos, the Serra do Cabral and the Southern Espinhaço Ridge, the latter compartment is made of 03 facies (West Face, Interfluve, and East Face). These geosystems confirm the geo-ecological diversity that exists in the contact between the Rio das Velhas Plain and the western edge of the Southern Espinhaço Ridge. The Karst of Monjolos is the most fragile geosystem and susceptible to impacts, while the Southern Espinhaço Ridge has the most resistant physical attributes with vegetation cover fragile.||Este trabalho realiza a aplicação da modelagem, proposta por Jansen (2013), na paisagem do contato entre a planície do Rio das Velhas e a Serra do Espinhaço Meridional. Esta área surge como amostra representativa de ampla diversidade geoecológica em razão de sua localização. O trabalho baseou-se nos conceitos de paisagem e de geossistemas de Bertrand (2004), norteando os trabalhos de campo de Couto e Travassos (2016), e permitiu a aplicação de modelagens de vulnerabilidades natural e ambiental. De oeste para leste, partindo do município de Corinto até Diamantina, tem-se a Planície do Rio das Velhas, o Carste de Monjolos, a Serra do Cabral e a Serra do Espinhaço Meridional, sendo este último compartimento composto por 03 geofácies (Face Oeste, Interflúvio e Face Leste). Estes geossistemas confirmam a diversidade geoecológica existente no contato entre a planície do Rio das Velhas, onde o Carste de Monjolos é o geossistema mais frágil e susceptível a impactos, e a Serra do Espinhaço Meridional, cujos atributos físicos são resistentes, porém a cobertura vegetal é determinante na fragilidade ambiental.
Abstract
NATURAL AND ENVIRONMENTAL VULNERABILITIES AT THE CONTACT BETWEEN THE RIO DAS VELHAS PLAIN AND THE SOUTHERN ESPINHAÇO RIDGE, MINAS GERAIS
This research realizes the application of the model, proposed by Jansen (2013), in the landscape in the contact between the Rio das Velhas Plain and the western edge of the Southern Espinhaço Ridge. This area is a representative sample of wide geo-ecological diversity due to its location. The research was based on the concepts of landscape and geosystems of Bertrand (2004), guiding field work of Couto and Travassos (2016), and allowed the model’s application of natural and environmental vulnerabilities. From west to east, from the municipality of Corinto to Diamantina, there is the Rio das Velhas Plain, the Karst of Monjolos, the Serra do Cabral and the Southern Espinhaço Ridge, the latter compartment is made of 03 facies (West Face, Interfluve, and East Face). These geosystems confirm the geo-ecological diversity that exists in the contact between the Rio das Velhas Plain and the western edge of the Southern Espinhaço Ridge. The Karst of Monjolos is the most fragile geosystem and susceptible to impacts, while the Southern Espinhaço Ridge has the most resistant physical attributes with vegetation cover fragile.
