This work investigated the physical parameters of the model of landscape of the Island of the Mosqueiro, in the Northeast of the State of Pará, in the Amazon region, using itself of investigative strategies that allowed insertions in the ambient order. In this chance the activities in the area of the geoprocessing. In the ambient context had been privileged this work present products of integration and other unknown ones whose idea is of instrumentalizer the local governmental politics, aiming at to contribute for improvement of the relation of the model of antropic occupation of the landscape versus maintenance of the quality and ambient preservation, in view of the necessity of if establishing a structure of adequate development to the current scenes. The importance of the District of Mosqueiro for Belém is unquestionable. Its history and tourist potential are peculiar; beyond the one that the island if establishes as important component to the social life, artistic, cultural and sporting of the majority of the population that composes the great Belém. To the long one of the time, the Island of the Mosqueiro was scene of many landscapes transformations. The performance of litologics, pedologics local factors as to those of order, of relief and, more recently, antropics, is used to explain the current arrangement of the landscape. In this direction the ecology of the landscape is presented as important boarding integrator for the search for the agreement of the Neogenic evolution. Inside of the flowing varied ones of studies on the shaped one of the landscape, it was opted to multitemporaly evaluating the evolution of the systems natural and constructed (landscape diversity), as well as the unknown application of metric of the landscape quantifying the current landscape situation and its possible future ambient impacts, ahead of the current strategies of occupation. Moreover, it searched integration of different variable as the ground, geology, geomorphology, neotectonic and the vegetal covering and use of the land of the Island of the Mosqueiro, for the attainment of the vulnerable areas the processes that are inserted in the dynamics of the same one, the example of the erosion. Thus, in the conduction of this research in the Island of the Mosqueiro the application sources had involved: geoprocessing; digital processing of images; metric of the landscape; and statistics and algebra of maps. The primordial data to this work had been: images of the Landsat satellite; deriving cartographic products of the aerophotogrammetry survey of Belém-PA; map of detailed ground survey; geology map; and information collected in field. The applicatory ones used for the attainment of the results had been the following ones: SPRING (version 4.0/Windows); ARCVIEW (version 3.3/Windows); SURFER (version 8.0); and FRAGSTATS (version 3.0). Amongst the main results reached in the study of the landscape of the Island of the Mosqueiro, they are distinguished: maps that portray the occupation dynamics (multitemporal analysis); space analysis of the current landscape structure (application of metric of the landscape); evaluation of geomorphology changes; framework current of the tectonic regimen (tectonics imperfections); and, finally, the map of vulnerability to the erosion.
