The Upper Coxim River Basin (UCB) has an area of approximately 1375 km located in the municipalities of So Gabriel do Oeste and Camapu in the state of Mato Grosso do Sul, Brazil. The aim of this work was to evaluate the environmental fragility of the UCB using fuzzy logic implemented at a Geographic Information System to propose a model of physical-territorial management. Spatial data used were arranged in a database implemented in a Geographic Information System (GIS). The generation of the physical-territorial management model was carried out considering preparation of UCB relief mapping, potential natural erosion, land-use and land-cover, environmental fragility and, environmental legislation. Results indicated a significant relationship between landforms and their uses: mechanized agriculture in the Chapada of the So Gabriel and livestock development on the Plateau Taquari hills. The guidelines set out by the type of land use proposals were: Priority areas for permanent preservation, priority area for rehabilitation and preservation and areas for sustainable use.
