MAPEAMENTO DA FRAGILIDADE AMBIENTAL NO TRECHO DE VAZÃO REDUZIDA DO RIO ARAGUARI (MG) UTILIZANDO TÉCNICAS DE GEOPROCESSAMENTO

Abstract

Studies of environmental fragility are tools to aid planners and managers make decisions that ensure an adequate management of the environment because they allow evaluating the potential of the environment in an integrated manner. Based on the empirical methodology to evaluate environmental fragility proposed by Ross (1994) maps of environmental fragility of the basin tributary of Reduced Flow Channel of Araguari River in the years 1979, 1999 and 2009 were made using GIS techniques. Using the synthesis cartographic products was possible to demonstrate that human action is responsible for the alteration of environmental fragility in the period analyzed, because changes in land use pattern created by human action, directly interferes with the fragility of the landscape, generating areas with the highest propensity to environmental degradation.
