摘要/Abstract

摘要： 2011年,在吉林市磨盘山次生林建立了1hm²的永久样地,调查了样地内胸径(DBH≧1cm)的所有紫椴个体。该样地共有紫椴653株,平均胸径6.39cm。运用Ripley's K函数分析了紫椴种群的空间分布格局。结果表明:1)所有紫椴个体以及紫椴幼树(DBH＜10cm)、紫椴小树(10cm≤DBH＜20cm)在空间上呈聚集分布格局,紫椴大树(DBH≥20cm)在空间上随机分布;2)不同发育阶段紫椴个体在空间上呈负关联关系。次生林紫椴的空间格局与紫椴的更新策略和种子传播有关。

Abstract: Based on investigation data from a permanent secondary forest plot of 1ha in Mopan Mountains,Jilin city,the structure of Tilia mandshurica population was analyzed.Ripley's K function was used to analyze spatial patterns of T.mandshurica population at different growth stages (saplings,small trees and big trees).The results showed that DBH structure of T.mandshurica presented a reverse “J” distribution and small age individuals accounted more.The spatial pattern of T.mandshurica population was clump for all stems,saplings and small trees,but random for big trees; spatial associations between different stages were repulsed .It indicates that seed dispersal and regeneration mechanism was a key factor to spatial pattern.

Key words: Mopan Mountains, Tilia mandshurica, Ripley's K, spatial pattern, spatial association
