ENVIRONMENTAL ANALYSIS THROUGH NETWORK GRAPHICS

ABSTRACT This article aims to discuss the erosive problem of the high basin of Areia Dourada stream, Marabá Paulista (SP), through a joint evaluation of the erosive forms with the physical and anthropic variables. From the methodological principles, we analyzed the information of lithology, soils, relief forms and relief energy, identifying the restriction to the use, conceived from the potential for erosion of the evaluated variables. This restriction was analyzed in conjunction with land use, making it possible to identify the compatibility and incompatibility relationship of the current use with the physical characteristics of the grounds and the erosive forms. This information was worked together from network graphics. As a result, we obtained a synthesis of the complexity between the combinations of the physical and anthropic variables, which allowed to indicate the forcing elements of the system, catalysts of the erosive processes, the mechanisms by which the processes evolve and the grounds subject to erosion, in case the current conditioners remain.
