Abstract

Treating geosystems as relatively homogeneous units brings up the possibility of attributing to the relief, a primordial role as a first taxonomic level of landscape analysis. To apply such a form of compartmentalization in an area of the Amazon is fundamental in view of the inexistence of mappings and documents that portray the landscapes of the Maranhense Amazon. The present article aims to identify the geoforms of the Pindaré River Basin-MA, as a first level of the geosystemic units, giving the factor relief and rock substrate, important highlights. The methodology consisted in using geoprocessing techniques and methods in order to find the variables slope, hypsometry, surface curvature, slope orientation, shaded relief and geology. As a result, it was possible to identify 14 units and 27 sub-units that were given the nomenclature of geoforms, each with unique geological and geomorphological characteristics that gave rise to many of the current features of the landscape of the western Maranhão region. Tabular plateaus and mountain ranges contrast with reduced plateaus and flat reliefs of the Amazon lowlands; amidst them, fluvial, fluvial-lacustrine and fluvial-marine plains also stand out in this important hydrographic basin. From these results, it was possible to obtain a proposal for hierarchization and mapping on a regional scale, helping in possible future planning proposals.
