珍稀濒危植物长苞铁杉群落物种多度分布模型研究

Study on species abundance distribution m odel of the race and endangered plant Tsuga longibracteata community

摘要: 用Weibu11分布模型拟合珍稀濒危植物长苞铁杉群落物种多度分布结果表明，长苞铁杉群落乔木层、灌木层物种多度分布均符合Weibul1分布，WdbuU分布模型应用于珍稀濒危植物长苞铁杉群落物种多度分布具可行性。

Abstract: This paper poses the Weibull model of species abundance distribution to simulate the species abundance distribution of the rare and endangered plant Tsuga Iongibracteata forest．The results show that the species abundance distributions of arbor layer and shrub layer of Tsuga longibracteata forest all follow the Weibull distribution，and it is feasible to use the Weibull model to simulate the species abundance distribution of the rare and endangered plant Tsuga longibracteata forest．
