SUMMARY:

Pedogeomorphology is defined as the study of the soil-relief relationship under different aspects: conceptual, methodological, operational and/or scalar. In landscapes, soils and reliefs evolve together, in this process, constantly, one influences the other in different ways, resulting in landscape implications and complex pedogeomorphological processes. Knowledge regarding the physical environment is essential to guide territorial planning policies, environmental preservation and recovery of degraded areas. The Brazilian semi-arid region is seen as a fragile region from an environmental point of view and still lacks scientific information that allows for a deeper understanding of its dynamics. The objective of this work was to carry out a pedogeomorphological characterization of the RPPN Olho d'água das Onças, located in the municipality of Picuí-PB, in the Brazilian semi-arid region. The geological substrate of the study area is associated with the Serra do Martins Formation (predominance of conglomerate, sandstone and laterites). A bibliographical and cartographic review of the region under analysis was carried out. For the characterization of the RPPN, cartographic products were elaborated in a GIS environment, using the QGIS software. The ALOS-PALSAR satellite image was used as a basis. Cartographic products were prepared, such as: MDE, slope map, geomorphological map and soil map. Field work was carried out with collections of seven soil profiles (Neossolo Flúvico P1; Neossolo Regolítico P2; Cambissolo Háplico P3; Cambissolo Háplico P4; Neossolo Regolítico P5; Plintossolo Pétrico P6; Latossolo Amarelo P7), representing different geomorphological compartments. Five geomorphological units were identified in the area: i) plateau, ii) escarpment, iii) valley with flat bottom, iv) structural valley, and v) river plain. The pedogeomorphological characterization of the RPPN provides relevant information for the future preparation of the Management Plan for the Conservation Unit. The identification of geomorphological units and associated soils enabled a better understanding of the potential and vulnerabilities of each sector. The area with flat relief (ith Latossolo) is the most appropriate for creating areas of intensive use. In turn, greater care must be taken with the edges of the plateau, with greater declivity and associated with poorly developed soils. In some areas, laterite degradation favors the formation of a concavity, with features of gently inclined ramps.
