Abstract

Landscape cartography is a methodology/activity of a physical-geographical nature that makes it possible to define units, attributing to them functions, limitations and potentialities linked to geoecological indicators. Given this premise, this article sought to identify, classify and map the landscape units of the coastal zone of Maranhão, especially the municipalities of Rosário, Axixá and Icatu, in the north of the state. The methodological guide covered geoprocessing precepts, in view of the data modeling linked to algebra map which allowed the crossing of geology, relief, slope and vegetation data, with their subsequent validation. The results showed ten units ranging from mangroves with herbaceous and arboreal riverine vegetation on reduced slopes superimposed on alluvium and colluvium, to units with urban influence. The typologies and dynamics of each unit made it possible to punctuate the cultivation, extractivism and livestock farming located in forest and countryside (natural) areas. As a result, those landscapes that are characterized by strong changes in spatial and functional structure may not fulfill their functions and services properly. It is concluded that this research will contribute to understand the coastal zone as a heterogeneous area from the geoecological point of view and to enable a future physical-territorial ordering of this complex and relevant region for Maranhão.
