In recent decade, the additive partitioning of species diversity has been revived, and used to describe a variety of diversity patterns. This paper analyzed the additive partitioning of tree species diversity in Tiantong National Forest Park, based on species richness, Shannon index and Simpson index. For species richness, small part was partitioned within plots, and most diversity was partitioned among plots or (sub-) associations. For example, in Schimeto-Castanopsietunm fargesii association, only 20.3% of the species richness was assigned within plots. However, for Shannon index and Simpson index, most diversity was partitioned within plots, because these indices gave consideration to both species number and its abundance in each plot. The results of additive partitioning were also compared to those of traditional method in this paper.
近十年来，物种多样性的加法划分得以复兴，并被用于描述各种多样性模式。本文基于物种丰富度、香农指数和辛普森指数，分析了天童国家森林公园树种多样性的加法划分。对于物种丰富度，小部分是在样地内划分的，而大部分多样性是在样地间或（亚）群落间划分的。例如，在木荷-栲树林群落中，只有20.3%的物种丰富度是在样地内分配的。然而，对于香农指数和辛普森指数，大部分多样性是在样地内划分的，因为这些指数同时考虑了每个样地中的物种数量及其丰度。本文还将加法划分的结果与传统方法的结果进行了比较。
