摘要
混交度表明了任意一个树的最近相邻木为非同种的概率。以参照树及其相邻最近 4株树组成的最小空间结构单元较“结构 4组法”更能恰当地进行林分空间结构分析。当借助整个林分的混交度分布或均值来分析树种空间隔离程度时最好附加说明混交林分的树种组成及其比例。这一点对精确分析树种空间分布及其结构重建意义十分重大。
Mingling was used to describe the probability of the closest neighboring tree in a forest being a different species. The minimum spatial structure unit consisting of a reference tree and its 4 closest neighboring trees is more appropriate than the “four group structure method” in analyzing spatial structure of forest stands. When using the distribution or the mean of mingling to analyze the spatial isolation of species in the stands, it is recommended that the species composition and their ratio in the mixture stand be described. The description has significant impacts on the precise analysis of species spatial distribution and structure restoration.
