Different uses of natural resources of the coastal landscape generate impacts that need to be known and studied. As far as the coastal zone is concerned, there is an aggravating factor, since it is formed by highly specialized, productive and ecologically and economically important environments. In addition, it has a high degree of urbanization and consequently a high settlement rate. The National Coastal Management Plan applied to the Amazonian coastal zone has operated in an incipient way, since there is still no political articulation between the municipalities involved and the other spheres of power, lack of a base of information and methodologies based on local experiences, which ensure the proper execution of the plan. However, other strategies on the knowledge of the coastal environments were executed, based on regional and national research edicts, applied to the municipality of Quatipuru, ensuring a good information base, which were useful for the purposes of this dissertation, which aimed at mapping the landscape units of the municipality of Quatipuru, Pará, which today has become a conservation unit, RESEX Marine category, with the monitoring and participation of public hearings. In this way, it is understood that it is a separation of the coastal landscape into homogeneous areas, denominated "landscape units", covers an analysis and treatment of data without the right to products of Landscape Ecology, through Remote Sensing with an application of computational programs of object oriented classification in Geographic Information Systems, generating specialization and even an understanding of landscape formation processes are not filters of geographic analysis. For the better definition and delimitation of landscape units, the vegetation unit was chosen as an essential element because it is the result of the dominant ecological processes in the coastal zone. In this way, a physiographic matrix was generated that aided the mapping by identifying two geomorphological units of regional expression: 1) the Lower Coastal Plateau, which is formed by secondary vegetation or capoeira in different stages of regeneration. Of particular note are the urban areas, formed by dense human occupation, including the municipal headquarters - Quatipuru and the community of Boa Vista, and other traditional communities, thus forming diverse groups of family farmers, fishermen, crabmen, that uses the secondary vegetation and the field areas with cattle and buffalo management differently. The sandy Coastal Plain is integrated by the restinga, in contact with the Atlantic Ocean, while the 3) Lamosa Plain is dominated by mangroves and saline fields. Note: 4) Alluvial plain with quite impacted floodplain forests by the removal of vegetation cover. In addition to these mapped units, paleorestingas bands with old and successive coastlines were identified in the interior of the mangrove, up to the present sandy range. Besides this, it was identified that each mapped unit has spatial relations of connectivity, adjacency and delimitation, with the adjacent unit, concomitantly. Such relationships spatially demonstrate the interactions of the ecological and anthropic processes that form the coastal landscape. Thus, the mangrove stands out as the largest and most important landscape unit, because it has a spatial relation with all other units, the flooded, saline or freshwater fields are always bordering the mangrove. The contribution of the research will mainly be to guide management and governance actions within the Marine Quatipuru-Primavera RESEX, combined with the elaboration of the municipal territorial planning plan.
