The Brazilian Cerrado represents one of the largest tropical savannas in the world in terms of biodiversity. In this sense, this work had as objective to know the distribution of species allied to the gradient generated by different soil types in the National Forest of Paraopeba (Flona) in MG. All trees with soil height circumference (CAS) greater than or equal to 10 cm within the plots were identified. In each plot, soil samples were collected with three replicates totaling 75 samples. Data on the chemical composition of surface samples of the five different soil types in this Cerrado revealed different chemical properties. There were no significant differences in the concentrations of P, K, Fe+ 2, Ca+ 2 and Al+ 3 in the soils of the type Yellow Latosol, Red Yellow Latosol and Cambisol, on the Cerrado stricto sensu, but the Mesotrophic Cerradon presented statistical differences Significant. A total of 51 species from 29 families were listed, which presented a number of individuals ≥ 20, making a total of 4,214 individuals. As for abundance patterns, Miconia albicans was the most abundant species in Cambisols and Yellow Latosol, followed by Alibertia edulis in Mesotrophic and Pera glabrata in Cambisols and Yellow Latosol. The Cerrado Distrophic on Red Latosol was characterized by the predominance of arboreal species on soil with higher content of Al+ 3 and the most abundant species was Coussarea cornifolia. The distribution of abundance is suggestive of the formation of functional groups and this is not by chance but determined by the gradient generated by different soil types in the Flona of Paraopeba.Keywords: Solo, Functional group, Paraopeba, Flona, Cerrado.
