| 摘 要： | 选取北京山区8块典型样地,根据样地调查结果,采用点格局分析方法,对群落内主要种群的空间分布格局及种间相互关系进行研究。结果表明：北京山区优势针叶树种群落内主要种群的分布格局随尺度的变化规律明显,主要以集群分布为主要特征,但不同优势树种群落的主要种群最大聚集程度和最大聚集尺度随林分类型的不同差异较大;主要种群之间的关系以显著性负相关关系为主,部分种群之间随着尺度的增加,种间负联结性减弱,无种群关系为正相关的针叶林群落。

| Abstract: | Eight typical plots in Beijing mountainous area were selected in this study.Based on the investigation results of these plots,the spatial distribution pattern and the interspecific relationship of main populations in the community were analyzed by the method of point pattern analysis.The results showed that the distribution pattern of dominant coniferous community changed by the scales obviously,and displayed the contagious distribution,but the maximum-aggregation scale and the maximum-aggregation extent of... |
