摘要
考察了太行山南段峡谷区小叶鹅耳枥群落,沿不同海拔布置样方,结合双向指示种分析(TWINSPAN)和典范对应分析(CCA)方法,分别对乔木层、灌木层进行数量分类和排序,并进行了环境解释。用TWINSPAN等级分类法将乔木层和灌木层各分为9个群丛,较好的反映了群落生境特征。CCA排序结果同TWINSPAN。CCA第一排序轴主要与植物所在环境的坡度相关,第二轴主要与坡向和海拔相关。CCA结果表明,坡度、坡向、海拔对不同功能层的植被类型、结构、分布所起到的作用具有一致性,其中坡度、坡向的影响比较明显,海拔的影响次之。
Arbors, shcrubs and herbage species were included for analyzing relations of different functional layers by using TWINSPAN and CCA. Results of TWINSPAN and CCA analyses were consistent. CCA ordination can reflect their spatial changes in graph of environment space. Results showed that the changes of aspect, slope and elevation can affect community type, structure and distribution of Carpinus turczaninowii forests and their functional layers, with the role of aspect and slope was more significant than that of elevation in the study area.
