This research about structural characteristics of evergreen broad-leaved natural forest was examined on the six permanent sample plots in the Ba Be National Park, Bac Kan province. The result showed that there were 18 dominant species in the study areas, in which some species with the highest composition coefficients as Streblus ilicifolius, Alphonsea, Glycosmis cymosa, Streblus saper and Scheffera octophylla. The average number of species and the average of density recorded were 41 species per plot and 442 trees per plot. The Shannon-Wiener diversity index (H') and Simpson index (D) were calculated at 2.5756 and 0.8497, respectively. The distance distribution showed the best to fit N-D distribution of the forest stands in the study areas. This study results have significantly contributed to the scientific basis for the management of natural forests in a sustainable manner in general and provided a basis for studying the dynamics of forest structures in the next stage.
