摘　　要：为探究黄海北部大鹿岛鹅耳枥群落特征及其与土壤环境因子的关系,以大鹿岛9个鹅耳枥群落的样地调查数据为数据源,采用植物区系成分、物种重要值、物种多样性和径级结构等指标表征群落特征,运用双向指示种分类法(TWINSPAN)和冗余分析方法(RDA)分析其土壤环境影响因子。结果表明:(1)大鹿岛鹅耳枥群落维管植物共计110种,隶属46科84属,包括种子植物44科82属107种和蕨类植物2科2属3种。种子植物区系成分大部分具有温带分布性质。群落乔木层、灌木层和草本层的优势种分别为鹅耳枥(Carpinus turczaninowii)、山花椒(Zanthoxylum schinifolium)和矮丛薹草(Carex callitrichos var.nana),重要值分别为52.84%、34.49%和21.54%。群落乔木层的物种较少,而灌、草层植物种较为丰富,群落尚未达到演替的顶极阶段。鹅耳枥种群径级结构反映出该群落由增长型种群构成。(2)聚类分析将鹅耳枥群落划分为4类群丛,排序分析结果在验证前述聚类分析结果合理性的同时,进一步佐证土层厚度、土壤全磷含量和pH值是影响鹅耳枥群落物种分布的主要土壤环境因子。To explore the community characteristics of Carpinus turczaninowii and their relationships with soil environmental factors on Dalu Island in the northern Yellow Sea,we carried out plot survey with nine C.turczaninowii communities on Dalu Island.We analyzed community characteristics by flora composition,species importance value,species diversity,and diameter structure,and determined the soil influencing factors by using two-way indicator species analysis(TWINSPAN)and redundancy analysis(RDA).The results showed that:(1)A total of 110 vascular plant species belonging to 46 families and 84 genera were recorded in the C.turczaninowii communities,including 107 species in 82 genera of 44 families of seed plants and 3 species in 2 families of 2 genera of ferns.Most of the seed flora composition had temperate distribution properties.The dominant species in the tree,shrub,and herb layers were C.turczaninowii,Zanthoxylum schinifolium,and Carex callitrichos var.nana,with importance values of 52.84%,34.49%,and 21.54%,respectively.Species composition of tree layer was relatively poor,while species of shrub and herb layers were more abundant.The community did not reach the climax stage of succession.The diameter size structure of C.turczaninowii populations reflected that the community was composed of growing population.(2)The cluster analysis classified the C.turczaninowii communities into four types of clusters.The ordination analysis results verified the rationality of the aforementioned cluster analysis results,and showed that soil thickness,soil total phosphorus content,and pH were the main factors affecting species distribution in C.turczaninowii communities.
