In this paper, it is accessed the landscape dynamics in the watershed Cinqüenta e Quatro and Sete rivers, from the use of TM/Landsat of 2002, 2004 and 2005 images, analyzed by supervised classification by regions. It was verified that the class Anthropic Forest still has a prominent role among the mapped units, while the pasture areas represent the dominant patters of land use. For the landscape dynamics, the greatest percentuals of stability occurred for the class Anthropic Forest and Advanced Secondary Regrowth. Among the classes of land use, the pasture areas were more stable, although small conversions occurred for the class Grain Agriculture.  aAmazonia  aHidrografia  aMicrobacia  aSensoriamento Remoto  aSolo  aUso da Terra  aBrasil  aPará  aParagominas1 aMACIEL, M. de N.
