Description: The southeastern region of Pará State, Brazil, is one of the critical areas of Amazon deforestation, due to the great transformations that have occurred there. This work had the objective of evaluating spatially the landscape dynamics in the areas of Lago Azul and São Francisco settlement projects, based in landscape metrics calculated by using a specific softwares. For this, it was used the land cover/ land use thematic products, by considering the Landsat Thematic Mapper (TM) images acquired in 1984, 1988, 1992, 1996 and 2000. It was observed that the curves showed by the different landscape metrics analyzed, have a tendency to reflect the fact that anthropization processes which occurred in the study areas, have shown distinct trajectories, due to the particularities of the migration flux and the strategies of land distribution. In general, the obtained results also express the gradual process of removal intensification of the Primary Forest, originally the major class, for annual crops and pasture formation.
