摘要
基于山西文峪河上中游森林群落的野外调查数据,采用植被数量生态学研究方法,对该区域森林群落进行分类与排序。利用双向指示种分析(TWINSPAN)方法对研究区森林群落进行分类,将52个森林样地分为13个群丛,优势群丛主要有群丛Ⅰ(白杄、歪头菜和披针薹草)、群丛Ⅱ(白桦、白杄、榛和披针薹草)以及群丛Ⅲ(青杄、美蔷薇和披针薹草)等。典型相关分析(CCA)结果表明,海拔是影响研究区森林群落分布和优势种分布的主控环境因子,优势种与环境、群落与环境具有较为一致的空间分布格局,即优势种与环境的相关性直接反映了群落与环境的相关性。研究结果为研究区森林群落的保护和管理提供参考。
Based on field survey data of forest communities in the upper and middle reaches of the Wenyu River in Shanxi Province,the forest communities in this area were classified and sorted by quantitative ecology of vegetation.Two way indicator species analysis(TWINSPAN)was used to classify the forest communities in the study area,dividing 52 forest plots into 13 clusters,the dominant clusters mainly include Cluster Imainly including Cluster I(Picea meyeri,Vicia unijuga and Carex lancifolia),Cluster II(Betula platyphylla,Picea meyeri Corylus heterophylla and Carex lancifolia),and Cluster III(Picea wilsonii,Rosa bella and Carex lancifolia).The results of canonical correspondence analysis(CCA)showed that altitude was the main controlling environmental factor affecting the distribution of communities and dominant species in the study area.Dominant species and environment,as well as communities and environment,had a relatively consistent spatial distribution pattern,that was,the correlation between dominant species and environment directly reflected the correlation between communities and environment.The research results provided references for the protection and management of forest communities in the study area.
