This work analyzes the biodiversity of evergreen rainforests in Binh Chau - Phuoc Buu Nature Reserve, Vietnam. 4 combinations of the dominant tree communities of the Dipterocarpaceae family were observed in the park: Dipterocarpus formation, Shorea formation, Anisoptera formation, and Vatica formation. The study found 104 species from 38 families (Dipterocarpus formation - 45 species, Shorea formation - 86 species, Anisoptera formation - 21 species, Vatica formation -26 species). The most common are woody plants from the Anacardiaceae family - 8 species, the plants from the Clusiaceae and Dipterocarpaceae family are on the second place - 6 species. In general, the four studied plant formations have a different number of various tree species in their composition. The study shows that under the dominance of Shorea roxburghii G. Don, the plant community has the greatest biodiversity of plant species, whereas the smallest number of plant species is observed in phytocoenoses dominated by Anisoptera costata Korth. Fluctuations in the values of biodiversity indices are caused by the heterogeneity of the growth areas and previous anthropogenic impact.
