摘要
the objective of this study was to analyze the floristic composition, diversity and similarity of a submontane, semideciduous tropical forest in marcelandia-mt, in an ecological tension area in the forest contact region. the 33 families and 92 species specimens were found in 4008 individuals, in 74 plots of 10m x 250 m. the families that contributed most frequently to the floristic composition were lauraceae (15.99%), melastomataceae (12.97%), sapotaceae (12.50%), fabaceae - mimosoideae (9.91%), burseraceae (9.13%) and moraceae (7.29%). the shannon-weaver diversity, simpson concentration and pielou evenness indexes indicated that the area presents relatively high diversity and low concentration of species with high uniformity in the ratios of individuals per species. the floristic similarity standards had low similarity among the evaluated areas evidencing the existence of phitogeografic standards based on the species distribution.
