The municipality of Ituiutaba is located in the state of Minas Gerais, specifically in the geographical mesoregion of Triângulo Mineiro e Alto Paranaíba. It has an municipal area of 2.598,046 km2 and an urban perimeter of 37,40 km2. The lack of data about the environmental characteristics and kind of land occupation are an obstacle to the preparation of environmental plans in the municipality. In this sense, the objective was to make a morphologic compartimentation of Ituiutaba following the taxonomy proposed by Ross (1992), comprising the 1st to 4th taxon. And the analysis of the environmental characteristics of the municipality was made following the methodology of Ab’Sáber (1969) on the Morphology Compartimentation, Superficial Structure and Landscape Physiology. The compartment was made from the research using the bibliography about the study area and the analysis of the past and current landform dynamic. The materials used were TM/Landsat 5 satellite images, aerial photographs and topographic maps. Thus, four major units have been mapped, being: Planalto de Ituiutaba, Superfícies de Cimeira, Chapada Embutida e Depressão Interplanáltica. The soil classes that were found are: red Oxisol; red-yellow Ultisol; Melanic Gleysol; Lithic Orthents and red Afisols. Whereas agriculture; pasture; natural vegetation; water bodies and urban area are the categories of land use found. This work will give data to a future study of environment vulnerability of Ituiutaba’s municipality.
