Study on Weibull Model for Species Abundance Distribution of Tsoongiodendron odorum Forest

Wu Chengzhen;Hong Wei(Resources & Evironment Dept. Fujian College of Forestry, Nanping, Fujian 353001)  
Species abundance distribution is an imporant content of biodiversity study. This paper first poses Weibull model of species abundance distribution to simulate the species abundance distribution of arbor layer,shrub layer and arbor+shrub layer of Tsoongiodendron odorum forest, the results show that they all follow Weibull distribution. This study enrichs the distribution model of species abundance distribution, and provides theoretic basis for management and protection to Tsoongiodendron odorum.
