树种组成式仅为一个文字表达式,不便于林分间进行树种多样性的定量分析与比较。本文引入Shannon物种多样性指数,提出树种组成指数的概念,用树种组成指数可以定量描述林分树种多样性。用树种组成指数表,可迅速查出树种组成指数,应用十分方便。
Tree species composition is only a text expression, not easy for tree species diversity quantitative analysis and comparison. In this paper, the Shannon species diversity index is introduced and the concept of species composition index is proposed. The tree species composition index can be used to quantitatively describe the diversity of tree species. With species composition index table, can quickly identify the tree species composition index, the application is very convenient.
