摘要:
选取翠竹、髯毛箬竹、菲白竹、铺地竹、毛竹和金佛山方竹6个竹种作为研究对象,运用空间点格局分析方法和Taylor幂法则对6个竹种的空间分布格局进行研究,分析不同距离尺度下6个竹种的空间分布格局类型,为优化优良竹种的空间种植结构提供理论依据,促进竹类资源在我国的开发利用。结果表明:(1)空间点格局分析和Taylor幂法则两种研究方法对6个竹种的空间分布检验结果一致;(2)翠竹、髯毛箬竹和铺地竹均呈现较强的聚集性分布特征;在给定的距离尺度下,菲白竹呈现较弱的聚集性;毛竹和金佛山方竹都介于聚集性分布和随机分布之间,但严格上应划为随机分布。

Abstract:
Taken six species of bamboos: Pleioblastus pygmaeus, Indocalamus barbatus, leioblastus fortune, Pleioblastus argenteostriata, Phyllostachys edulis and Chimonobabusa utilis as objectives, the spatial distribution patterns of these six bamboo species on different distance scales were analyzed using the spatial point pattern analysis method and Taylor’s power law, to provide a theoretical basis for optimizing planting structure of some bamboo species with potential great economic and ecological values, and to enhance the exploitation level of bamboo resources in China. Results showed that: (1) the putative spatial distribution types of these six bamboo species by using Taylor’s power law were consistent with using the spatial point pattern analysis method. (2) P. pygmaeus, I. barbatus and P. argenteostriata all exhibited a strong characteristic of aggregated distribution, whereas P. fortunei showed a weaker aggregated distribution on given distance scales; the spatial distribution patterns of P. edulis and C. utilis were between the aggregated distribution and random distribution on given distance scales, which should be strictly classified as a random distribution.
Key words:  distance scale  K function  Monte-Carlo test  Taylor’s power law
