【 摘 要 】

The incorporation of the Multicriteria Decision-Making methodology from fuzzy logic to the environmental data model has allowed an arrangement mapping of environmental fragility (Ross, 1994) from the studies of the hydrographic carstica bassin. At the first step of methodology were applyied different criteria to overcome the strict classification of soils. In the second step, the Analytical Hierarchy Process wich uses fuzzy logic allowed to determine differences among the soil, slope, geology and geomorfology, with major value ascribed to the soil. This way, it’s possible to remark that the purposes of alternative methodology presented a very different output from those of Ross (1994), as the last one based his presuppositions on sustainability theoretical debate.
