The morphopedological approach when using the soil-relief-geology relationship of a given area, allows the understanding of the landscape structure, serving as a basis for implementing environmental policies for land use and occupation. The study area comprises the municipality of Bom Jesus, state of Rio Grande do Norte, located in a geopedoclimatic transition area, in the rugged state of Rio Grande do Sul, where physical information, on a regional scale, cannot meet the basic level of necessary details environmental management at the local scale. In this context, the objective of the present work was to carry out a morphopedological analysis of the municipality of Bom Jesus-RN, based on the methodology of Castro and Salomão (2000), with field surveys, laboratory and mapping of the morphopedological units considered homogeneous in a GIS environment. The combination of soil-relief-geology made it possible to divide the relief into four morphopedological units, called Conserved Pediment, Dissected Pediment, Pediplane and Inselbergs in Tors, with surfaces ranging from flat to smoothly wavy, except for Inselbergs. In soil associations, three subclasses of NEOSOLOS and one of LUVISSOLOS were identified. Land use and occupation identified eight classes with the following percentages: short cycle crops with 50.53%, grasses / pastures with 18.09%, sparse caatinga 18.96%, dense caatinga 1.50% and hydrography with 2.64% of the municipal area. In view of the results presented, it was verified the importance of understanding the morphogenetic processes, their classifications, and their uses associated with geomorphological compartments. Thus, in addition to contributing to a better understanding of the geology-relief-soil relationship in the landscape structure, the perspective of this work aims to enable subsidies for decision making by public managers in the planning and territorial management of the municipality.
