Relações morfopedológicas no geossistema ferruginoso do Parque Nacional dos Campos Ferruginosos, Carajás-PA

Abstract

The soils are important means of studies regarding the processes that restrict the evolution of the relief, since it is from them that the preservation of materials related to its modeling events occur. In the Southeast region of Pará, especially in the Campos Ferruginosos National Park, there is the occurrence of ferruginous materials that correspond to the relief model, but there are no detailed studies on it. The general objective of the research is to identify and analyze through the morphopedological approach the interrelationship between soil and relief that constitutes the landscape of Campos Ferruginosos National Park, thus supporting environmental planning actions. To this end, we used the theoretical and methodological bases of Landscape Geoecology, associated with the free software QGis 2.18.18, used for interpretation and processing of spatial data information. The characterization and identification of the area conditioners was necessary for the determination of the natural physical parameters leading to a preliminary interpretation of the geology, geomorphology, hydrography, pedology and vegetation of the area. In addition, the GPS points for crossing data in cabinets with the morphology / relief and hypsometry data allowed a better spatialization of the information. The morphopedological approach proved to be adequate and very useful for the elaboration of the work, since from this approach it was possible to map and identify, in the study region, seven relatively homogeneous pedoenvironments regarding the interaction between the geological substrate, relief and soils, called Morphopedological Compartments. Finally, the results generated may serve as a basis for the environmental planning and management of the Park, allowing subsidies for future studies of the management plan and management of the area in question.
