Abstract:Species relative abundanee distribution in Tsoongiodendro odorum community in Wanmulin Nature Reserve，Fujian Province, was studied by using patterns of geometric series distribution，log series distribution, log normal distribution，broken stick modeI and W eibul1 distribution to evaluate the simulation of such methods．Twenty-two species in tree layer were randomly investigated，and 33 species in shrub layer were surveyed in a quadrat of 5 m × 10 m．The simulation results show that the species relative abundance of tree layer in the community can be well described by all the models mentioned above，while that of shrub layer can be well described by log series distribution, log normal distribution and Weibull distribution．It is suggested that these methods might be useful for the
protection of biodiversity of the community dominated by endangered Tsoongiodendron oderum．
