                         analyzes the spatial pattern of alterations in land cover in the 
                         municipalities directly affected by the Tucuru{\'{\i}} 
                         reservoir. This analysis was carried out by using Landsat 
                         satellite images. The mapping of the land cover classes and the 
                         quantitative characterization of the classes present in the region 
                         were carried out between the start period of the II phase and the 
                         conclusion of the construction of the Tucuru{\'{\i}} 
                         hydroelectric power plant. The study was carried out in two 
                         phases, the first one corresponds to the application of the linear 
                         model of mixing in Landsat-TM and ETM+ segmented images, executed 
                         for the mapping of the land cover classes. The second, corresponds 
                         to the calculation of landscape metrics, with the purpose of 
                         quantitatively characterizing the classes. The results revealed 
                         alterations in the spatial pattern of forest cover around the 
                         Tucuru{\'{\i}} Lake. The municipality of Novo Repartimento was 
                         the one that presented the largest expansion of deforested areas 
                         and is also the municipality that houses most of the reservoir. 
                         The high level of fragmentation is associated with highways and 
                         country roads in the region, which allow connectivity between 
                         urban spots, facilitating access to new areas and conversion of 
                         forests into large areas for agribusiness.",
