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。
Spatial structure information is very important for the management of mixed-aged mixed forests. According to forest inventory and forest managers, the spatial structure can be described from three perspectives. There are currently available parameters for describing interspecies crossover and size differentiation, which can be obtained from surface surveys with appropriate costs. However, there is currently no such effective method for the distribution pattern of individuals. The proposed criterion can significantly reduce the cost of investigation and make it possible to reconstruct the spatial structure of the stand near detailed structural analysis. With its mean value W, the individual distribution patterns of trees, ie, random, cluster-like distribution, can be determined relatively accurately.
