摘　　要：多样化的森林群落为植物生长提供了不同的微生境。然而,物种在不同类型森林群落中是呈随机分布还是生态专化仍有待阐明。基于不同优势物种群落在太行山猕猴国家自然保护区建立了4个1 hm^(2)(100 m×100 m)森林动态监测样地,采用Kruskal-Wallis方法、Betadisper检验分析不同群落间的物种组成和结构差异,利用相关网络和指示种分析探索物种-群落间的关系。结果表明,不同群落间木本植物的多度、丰富度和物种组成存在显著差异;共有5种物种同时出现在四个群落中,有43.82%(39/89)的物种分布在两个或两个以上的群落中;网络分析结果显示,物种与群落之间的连接指数为41.29%,专化指数为60.89%;指示种分析显示不同植物群落间指示物种不同。了解了太行山猕猴国家自然保护区不同群落的物种组成和群落结构特征。研究结果同时表明,木本植物在不同群落中的分布具有较高的专化特征。希望本研究能为该区域木本植物多样性维持机制的理解和物种保护提供一定参考。The diversified forest communities provide different microhabitats for plant growth.However,whether the species are randomly distributed or ecologically specialized in different forest communities remains to be elucidated.In this study,four 1 hm^(2)(100 m×100 m)forest dynamic monitoring plots based on different dominant species communities were established in Taihang Mountain Macaque National Nature Reserve.We analyzed species composition and structure differences by Kruskal-wallis method and betadisper test in different communities,and then analyzed the plant-community relations by correlation network approach and indicator species analysis.Results showed that the abundance,richness,and species composition of woody plants exhibited significant differences in different communities.A total of 5 species were recorded in each of the four communities,and a total of 43.82%(39/89)species distributed in two or more communities.The results of network analysis showed that the linkage index between species and communities was 41.29%,and the specialization index was 60.89%.Indicator species analysis showed that the indicator species were different among different plant communities.Through this study,we understood the species composition and community structure characteristics of different communities in Taihang Mountain Macaque National Nature Reserve.The results also suggest that the distribution of woody plants in different communities showed high specialization characteristics.It is hoped that this study can provide some references for understanding of the mechanism of woody plant diversity maintenance and species conservation in this region.
