Abstract: We used the plot investigation method to study the species composition and species diversity of a Hopea reticulata forest in Ganshiling Natural Reserve, Hainan Island. The results showed that: (1) 163 species in 128 genera and 64 families of vascular plants were recognized. A total of 90 tree species belonging to 66 genera and 40 families were identified and 25 species of rattans from 23 genera and 18 families were recorded. The shrubs contained 29 species, 24 genera and 17 families and a total of 21 species of herbs belonging to 20 genera, 14 families were recorded. (2) The proportions of dominant species and constructive species were low. (3) Compared with other tropical communities, the species diversity indexes of this community were relatively lower with the Margalef index of 27.038, Shannon index of 3.647, Simpson index of 0.944, Pielou evenness index of 0.716 and species dominance index of 0.054. (4) The Margalef index and the Shannon index of each layer of the community were in order of tree layer > shrub layer > liana layer > herb layer, and the Simpson index and the Pielou evenness index were in order of tree layer > liana layer > shrub layer > herb layer, while the species dominance index was in order of herb layer > shrub layer > liana layer > tree layer.
