ANÁLISE INTEGRADA DE DADOS ESPACIAIS UTILIZANDO MULTICRITÉRIO PARA A DELIMITAÇÃO DE CORREDORES ECOLÓGICOS

Abstract

The objective of the research was to analyze the spatial relationship of the variables of the physical environment, using methods of multicriteria analysis for the delimitation of  ecological corridors. Were used the procedures adopted by Ross (1993) for environmental fragility and by Saaty (1997), the decision method in hierarchical levels (AHP) using the ArcGis and Spring software. The results indicate that the study area has 69.5% very weak and weak fragility, being influenced by pasture and vegetation fragments and the medium and strong fragility classes have a total of 28.33% of the area considered to have potential for the erosion process to occur. In the assessing the distance of the physical variables, it was possible to identify the behavior of the variables and define the choice of the most favorable areas for the delimitation of ecological corridors. In the corridor viability map, we identified that 52% has very high and high viability of the study area.
