                         great interest of generating clean energy in the countries of the 
                         region for energy supply and continuous economic growth, motivates 
                         the planning and construction of large hydroelectric projects, 
                         with a significant presence in the Amazon basin. Nevertheless, due 
                         to the extent of the reservoirs generated by these projects, the 
                         dynamics of natural ecosystems may be altered. To better 
                         understand the spatial pattern of land cover changes fostered by 
                         large hydroelectric reservoirs, this study applied the linear 
                         mixture model in segmented Landsat-TM and ETM+ images, and 
                         landscape metrics for the mapping of land cover classes in 
                         municipalities directly affected by the Tucuru{\'{\i}}-PA 
                         reservoir, and the quantitative characterization of the classes 
                         present in the region, between the periods of completion of the 
                         1st phase and the beginning of the 2nd phase of construction of 
                         the Tucuru{\'{\i}} hydroelectric plant. The results of the 
                         spatial analysis indicated that there were modifications in the 
                         spatial pattern of the forest cover in the surroundings of the 
                         Tucuru{\'{\i}} reservoir, with differentiated behaviors in the 
                         scale of municipalities, in which the high level of fragmentation 
                         is associated to the connectivity of the highways between the 
                         urban spots present in them, facilitating the access and 
                         conversion of forest areas into pasture.",
