。通过在10m×25m的1 cm网格上跟踪植物个体，描述了在最初裸露的泥炭表面上建立的植物种群在5年期间的大小和空间排列的变化，并对种群的空间格局和物种间的关联进行了统计分析。研究地点被14种多年生植物很慢地定植。演替早期以长喙苔草为主，空间分布呈簇状，分布均匀的绒毛绒毛藻和樟子松为优势种。种群规模的增长和空间分布的变化都被解释为物种扩散能力、对底物严酷的耐受性和繁殖模式的结果。
. Changes in size and spatial arrangement of plant populations established on an initially bare peat surface were described over a period of 5 yr by following plant individuals on a 1-cm grid in an area of 10 m x 25 m. The spatial pattern of populations and association between species was analyzed statistically. The study site was very slowly colonized by 14 perennial plant species. The early successional stage was dominated by Carex rostrata, with a clumped spatial distribution, and the homogeneously distributed Eriophorum vaginatum and Pinus sylvestris. Both the growth in size of populations and changes in their spatial distribution were interpreted as a result of species dispersal ability, tolerance to severity of the substrate and pattern of reproduction.
