In this study, the features and species diversity of the Cerbera manghas communities in Dazhou Island, Wanning, Hainan were studied based on field investigation, in order to provide references for the germplasm conservation, the reasonable matching of coast shelter-forest species and the ecological restoration of mangrove forest. There were 62 species in 58 genera and 37 families of vascular plants in the quadrats. Cerbera manghas, Ardisia humilis, and Peristrophe bivalvis occupied the predominant position in the tree layer (36.45% of Importance Value (IV)), shrub layer (8.31% of IV) and herb layer (25.53% of IV) respectively. Flora of seed plant was dominant with tropic zone. The pantropic type was the most widely distributed form, with 27 families and 17 genera. The Margalef’s index, Shannon-Wiener index and Pielou’s index order of all layers in the community was shrub layer>tree layer>herb layer. The pattern of the Simpson index was shrub layer>herb layer>tree layer.

Key words: Dazhou Island, Cerbera manghas, mangrove forest, flora characteristics, species diversity
