| 摘 要： | 空间结构信息对异龄混交林经营特别重要.按森林资源清查和森林经理的观点,空间结构可从3个角度加以描述.对于描述种间混交和大小分化目前已有可使用的参数,这些参数用适当的花费就可以在地面调查中获得.但对于个体分布格局目前还没有如此有效的方法.本文提出的角尺度可明显地减少调查花费并使详细的结构分析和接近实际的重建林分空间结构成为现实.借助于它的均值(W)可以相对精确的确定出现实林分中林木的个体分布格局即规则、随机和团状分布.

| Abstract: | There is an
ever-increasing need for information relation to the spatial structure of uneven-aged
mixed forests.Forest structure may be described on three levelsthe level of species
mingling,the level of tree size differentiation and the level of the tree point
distribution.Suitable parameters are available for characterizing mingling and size
differentiation,but the same cannot be said about the distribution of tree positions.The
neighbourhood pattern,a new spatial parameter presented in this paper can be assessed with
little effort in the field,without having to measure distances.It can be used to describe
and reproduce stands with certain spatial characteristics(clumped,regular or random). |
