| Abstract: |
| Based on the investigation of Syzygium hancei community along the coast of guangxi，the
characteristics and distribution mechanism of the species composition were studied，the relationship among different
groups in the community was explored，to provide a scientific basis for the protection and development of S. hancei.
Three representative communities of S. hancei along the coast of guangxi were selected to build plots，the species
and quantity was investigated，the diversity characteristics of S. hancei were analyzed from community structure and
important value index. The results shoued that in the community of S. hancei along the coast of Guangxi，there were
73 plant species，belonging to 39 families and 66 generas，including 44 species of trees，11 species of shrubs，10
species of herbs，8 species of vines. S. hancei was the dominant species in tree layer，other building groups included
Neolitsea alongensis，Garcinia oblongifolia，Acronychia pedunculata，Symplocos poilanei and so on. The dominant
species in shrubs layer included Neolitsea alongensis，Acronychia pedunculata and Dasymaschalon rostratum. The
species was rich in the community of S. hancei along the coast of Guangxi. S. hancei had absolute advantage in tree
layer，but its advantage decreased with age community increasing. The dominant species in tree layer and shrubs
layer were different in different places. |
