- Abstract
The present article aims to conduct a geoecological study on the coastal landscape of Aracaju/SE, based on functional, structural and anthropogenic approaches. The methodological procedures adopted were the evaluation of the horizontal and vertical dimension of the landscape, based on the individualization, mapping and analysis of geoecological units and subunits. From the observation of relatively homogeneous complexes, six units were delimited: Marine Terrace, Deposits Associated with the Coalescence of Sand Banks, Dunes Field, Tidal Flat, Recent Sedimentation Environments and Technogenic Deposits. The analyzed units revealed differentiated structures, forms, functions and genesis, nevertheless they constitute the same unit of relief - the coastal plain. The genesis and structure of the units are mainly associated with fluviomarine dynamics and anthropic derivations. Regarding the landscape mosaic that has been studied, we can highlight the Deposits unit associated with the Coalescence of Sand Banks that went through natural derivations, from which part of the Tidal Flat and Dunes Field units were originated; and anthropic derivations, which resulted in the emergence of the Technogenic Deposits unit. The functions performed by the units are associated with receiver/accumulator zones that have low energy flow and low altimetry - Marine Terrace and Tidal Flat; with areas of accumulation and dispersion - Dunes field; and with Transmitter and Receiver/Accumulator Zones - Sedimentation Environments. We can also highlight degrading geoecological processes associated with the continuous anthropic intervention, which have resulted in the loss of attributes and systemic properties that guarantee the fulfillment of geoecological functions and mechanisms of selfregulation of the evaluated landscape.
