Abstract:

In this study, floristic composition, community structure, and phytogeographic characteristics in a Lithocarpus glaber-Cyclobalanopsis glauca forest community were investigated in a 1 hm2 permanent plot (100 m×100 m) located in Dashanchong state-owned forest farm (113°17'46″-113°19'8″E, 28°23'58″-28°24'58″N), Changsha County, Hunan Province. The results showed that plants with diameter at breast height (DBH) larger than 1 cm in the plot belonged to 73 woody species, 55 genera, and 38 families. Evergreen broadleaved and deciduous tree species shared a similar proportion of composition (i.e. evergreen broadleaved 50.68% and deciduous 49.32%), but no large woody vines were found in the forest community. Fagaceae had the highest important value (35.94) and was the most dominant family in the community. The distribution of plant individuals, species, DBH classes, and height classes all displayed a reverse "J" pattern, indicating the apparent vertical canopy stratification and good understory regeneration in the forest community. The flora had the typical characteristics of subtropical flora with extreme similarity with the forest community in Japan and belonged to L. glaber-C. glauca formation group of typical evergreen broadleaved forest in the eastern region, China. The origin time of the forest community should not be later than the tertiary period.

Key words: evergreen broadleaved forest, phytogeographical floristic composition, community structure, Sino-Japan forest region, community origin
