Nonparametric species richness estimations of the monodominant Gilbertiodendron forest and the adjacent mixed forest.

*A total of 211 tree species and morphotypes were recorded from plot surveys (a total of 3 ha for each forest type). n represents sample size (number of 20 m×20 m quadrats); Spobs and Indobs represent total number of species and individuals observed, respectively. ACE, ICE, Chao1, Chao2, Jack1, Jack2, Bootstrap, MMRuns and MMMeans are nonparametric species estimators. Number in parentheses represents the proportion of the estimated species richness that was observed.

本研究通过样地调查共记录到211个树种及形态型，每种森林类型的调查样地总面积为3公顷。其中n代表样本量（即20米×20米样方（quadrat）的数量）；Spobs与Indobs分别代表观测到的物种总数与个体总数。ACE、ICE、Chao1、Chao2、Jack1、Jack2、Bootstrap、MMRuns及MMMeans均为非参数物种估计器（nonparametric species estimators）。括号内的数值代表观测到的物种丰富度占估计物种丰富度的比例。
