摘　　要：为揭示群落结构与功能分析,加强对森林生态系统的有效管理,为保护区常绿阔叶林的保护和生态恢复提供科学依据,对贵州省习水国家级自然保护区森林群落进行了Jaccard相似性与聚类分析。结果表明：群落Jaccard指数在0.50以上占总数的10.6%,大部分样地群落之间的相似性系数在0.1~0.49。保护区森林群落在水平结构上镶嵌性不明显,在垂直分布上差异明显。以植物的重要值数据进行聚类分析,保护区森林群落可以划分为11种群落类型,分别为润楠群落、厚皮栲群落、杜英群落、杉木-柃木群落、杉木-福建柏群落、丝栗栲-福建柏群落、鹅掌楸群落、丝栗栲-山矾群落、石栎群落、卫矛群落、丝栗栲-柃木群落,较全面地反映了群落的组成结构及群落的生境。The forest communities in Xishui National Nature Reserve were analyzed by Jaccard similarity and cluster analysis to reveal community structure and functional analysis,strengthen the effective management of forest ecosystems,provide the scientific basis for broad-leaved evergreen forests protection and ecological restoration.The results showed that communities with Jaccard index over 0.50 accounted for 10.6% of the total,most of the similarity coefficients between communities ranged from 0.1 to 0.49.The community mosaicism was not obvious in the horizontal structure,but significantly different in the vertical distribution.The cluster analysis based on important values of plants showed that the forest communities could be divided into 11 types,including Machilus pingii community,Castanopsis chunii community,Elaeocarpus decipiens community,Cunninghamia lanceolata-Eurya japonica community,Cunninghamia lanceolata-Fokienia hodginsii community,Castanopsis fargesii-Fokienia hodginsii community,Liriodendron chinense community,Castanopsis fargesii-Symplocos sumuntia community,Lithocarpus glabra community,Euonymus alatus community and Castanopsis fargesii-Eurya japonica community,the cluster analysis comprehensively reflected the community constitution and habitat.
