以往在长白山植物群落生态学的研究中极少考虑物种间的亲缘关系。由物种亲缘关系所度量的群落谱系结构可以反映进化与生态过程对群落结构的影响,因而可以从全新的角度来了解群落构建的成因。文中研究以长白山76块样地为基础,分析了群落的谱系结构以及环境因子对其所造成的影响,结果显示:各样地、各群落类型均表现出一定的谱系结构,表明长白山植物群落构建过程主要是受生态位机制的作用;海拔、林分郁闭度、坡度及土壤腐殖质厚度与谱系结构存在显著的相关性。进一步将群落谱系结构结合环境因子的分布状态进行分析可以推测,环境压力作为生境过滤的形式是高山苔原以及岳桦林群落构建的最主要驱动力;干扰与环境压力对低海拔阔叶林群落构建起到重要作用;环境压力的缺失使得竞争作用放大,这成为决定阔叶红松林群落结构的主要方面。
In the past, the research on plant community ecology in Changbai Mountain seldom considered the genetic relationship among species. The phylogenetic structure as measured by species kinship can reflect the impact of evolution and ecological processes on community structure, so that we can understand the causes of community construction from a completely new perspective. Based on the study of 76 plots in Changbai Mountain, the author analyzed the pedigree structure and the influence of environmental factors on the plots. The results showed that all plots showed certain pedigree structure, indicating that the plant community in Changbai Mountain The process is mainly affected by the niche mechanism; altitude, stand density, slope and soil humus thickness and pedigree structure have significant correlation. Further analysis of the distribution of community pedigree and environmental factors can be speculated that environmental pressure as the form of habitat filtration is the most important driving force for the construction of mountain tundra and the community of erhualia birch forest. Play an important role; the lack of environmental pressure makes the competitive role of amplification, which became the deciduous broad-leaved Korean pine community structure of the main aspects.
