How individual species structure the community in Dinghushan 20 ha forest plot

The large permanent forest plots have been an important platform for researches in community constructions.Interaction of individuals in community plays an important role in construction of community.Previous studies mostly focused on the interac-tions among species,and few of attentions were paid to how individual species construct a community.Comparative with result of BCI plot,we used the individual species-area index(ISAR) to analyze how the individual species construct the community in DHS plot.The result revealed that,unlike BCI plot and Sinharaja plot,majority of big trees are neutral in DHS plot.For smaller trees,both BCI and DHS plots showed a similar result that the number of accumulator species decreased along with the increase of radius scale,while neutral species increased.This indicated that individual species plays a different role in construction of different community at different development stages.Further studies should be focused on the forward exploitation,integrating others community informa-tion(such as,phylogeny and spatial structure et al) in the role of individual species on community.
