This paper presents a comparative analysis of the natural predisposition of land to erosive processes and soil loss, based on the application of two methodological models used in environmental fragility and environmental vulnerability studies in the same area, Anicuns river basin, Goiânia-GO. The application of these empirical models resulted in the creation of two different mappings, which were analyzed and compared to each other. The first methodological model, Urban Environmental Fragility bases on slope classes. The second empirical model, Natural Vulnerability to Soil Loss bases on Basics Territorial Units. The cartographic representations derived from the application of the empirical models allow the identification, hierarchy and analysis of areas according to the different levels of susceptibility to erosive processes, constituting on guiding tools in the process of territorial zoning of hydrographic basins, being able to subsidize the strategic environmental planning. Analyzing the final products, despite the differences between the methodologies, regarding the adoption of the variables and the results related to the information plans, the summary maps presented similarities regarding the final classification, being the correlation between them considered as very strong.
