The region of Vão do Paranã, inserted in the northeast (2000), is one of the three main centers of endemism in the Cerrado and goes through a process of fragmentation, which determines the ratings of potential and environmental vulnerabilities to promote appropriate policies of occupation. The study proposed here has as reference the integrated analysis of the landscape using the morphopedological compartments, to evaluate the dynamics of landscape structure in the microregion of Vão do Paranã. The methodology was based on the interpretation of Landsat images for temporal analysis (1984-2015) the use and soil coverage, with analysis of landscape structure through metrics and evaluation of morphopedological compartments. The results indicate that the characteristics associated morphopedological compartments the dynamics of occupation of the region respond by different forms of occupation of this area and the way it is structured the landscape in the region. Along the evolution of the use, the remaining vegetation concentrated in the eastern portion, coinciding with areas of emphasis more bustling, where currently the UC's; in the western portion, where the areas are more flat, there is a higher concentration of anthropic uses and high levels of fragmentation of the landscape. Although the agricultural expansion process has not yet strengthened in the region, the remaining areas were converted to 8.44% in anthropic areas, the pasture aptitude is present, however the agricultural areas have been growing exponentially in all compartments. The compartments favored, by relief, for anthropic occupation correspond to CMP I and III. The other compartments are indicated for the maintenance of environmental conservation.
