| 摘 要： | 以长白山5.2 hm2椴树红松林固定监测样地为基础，研究优势种红松与紫椴的径级结构，运用Ripley's K函数探讨红松和紫椴不同生长阶段个体的空间分布格及其空间关系。结果表明:①红松和紫椴的径级结构均呈单峰分布，幼树数量较少。②红松和紫椴种群在空间上呈聚集分布，红松和紫椴幼树主要表现为随机分布，小树和大树主要表现为聚集分布，但大树的聚集强度小于小树。③红松小树与大树在1 m的空间尺度上呈显著正相关；紫椴幼树与小树、幼树与大树在较小的空间尺度上呈显著正相关；红松小树与紫椴大树、紫椴小树与红松大树在局部空间尺度上呈显著正相关。

| Abstract: | A 5.2 hm~2 sample plot of Tilia-Korean pine forest was founded in Changbai Mountain in 2007.DBH class structure of dominant tree species Pinus koraiensis and Tilia amurensis was analyzed,and spatial distribution patterns and associations in different growth stages were also examined based on Ripley's K function. DBH class of P.koraiensis and T.amurensis both presented a unimodal distribution with few saplings.Ripley's K function indicated that both species had an aggregated distribution,saplings mainly show... |
