摘　　要：【目的】以台州地区雁荡山系和括苍山系森林群落为研究对象,研究2类山系森林群落结构和物种组成差异及其成因,为了解台州地区常绿阔叶林变化提供技术支撑。【方法】基于雁荡山系11个和括苍山系15个20 m×20 m森林群落样地调查结果,结合冗余分析(RDA)等方法,分析样地物种组成、径级结构及其与环境因子的关系。【结果】雁荡山系森林群落共记录乔木67种,隶属31科46属,括苍山系森林群落共记录乔木89种,隶属38科62属。2类山系森林群落重要值≥1%的共有物种有木荷Schima superba、枫香Liquidambar formosana、樟树Cinnamomum camphora、杉木Cunninghamia lanceolata、檵木Loropetalum chinense、窄基红褐柃Eurya rubiginosa、青冈栎Quercus glauca、苦槠Castanopsis sclerophylla、水团花Adina pilulifera、隔药柃Eurya muricata和白花龙Styrax faberi。括苍山系森林群落中木荷重要值为27.37%,比雁荡山系高16.80%。雁荡山系森林群落Shannon-Wiener指数、Pielou均匀度指数均显著高于括苍山系(P<0.05)。2类山系森林群落物种总个体径级结构呈倒“J”型。全氮、岩石裸露率、pH、土壤全碳和土壤电导率是影响2类山系群落多样性指数的主要因素。【结论】2类山系森林群落具有相似优势物种,雁荡山系森林群落的Shannon-Wiener指数与Pielou均匀度指数显著高于括苍山系。2类山系森林群落的主要差异是括苍山系森林群落的木荷重要值明显高于雁荡山系。[Objective]Taking the forest communities of Yandang and Kuocang Mountains in Taizhou as the research objects,this study focuses on the differences of forest community structure and species composition of 2 mountain systems and their causes,which provides technical support for understanding the changes of evergreen broad-leaved forests in Taizhou.[Method]Based on the survey of 11 plots in Yandang Mountain and 15 plots in Kuocang Mountain(20 m×20 m),species composition,diameter structure and their relationships with the environmental factors were analyzed using methods such as Redundancy Analysis(RDA).[Result]Forest communities of Yandang Mountain recorded 67 species of trees,belonging to 31 families and 46 genera while those of Kuocang Mountain recorded 89 species of trees,belonging to 38 families and 62 genera.Species having important values≥1%in the forest communities of Yandang and Kuocang Mountains were Schima superba,Liquidambar formosana,Cinnamomum camphora,Cunninghamia lanceolata,Loropetalum chinense,Eurya rubiginosa,Cyclobalanopsis glauca,Castanopsis sclerophylla,Adina pilulifera,Eurya muricata,Styrax faberi.The important value of Schima superba in the forest communities of Kuocang Mountain was 27.37%,which was 16.80%higher than that in Yandang Mountain.Shannon-Wiener index and Pielou evenness index of the forest communities of Yandang Mountain were significantly higher than those of Kuocang Mountain(P<0.05).The total individual diameter distribution of species in 2 forest communities showed inverted“J”shapes.Total nitrogen,rock exposure rate,pH,soil total carbon and electrical conductivity were the main factors affecting the diversity indexes of forest communities of 2 mountains.[Conclusion]Shannon-Wiener index and Pielou evenness index of Yandang Mountain forest community were significantly higher than those of Kuocang Mountain forest communities.The main difference between 2 mountain forest communities is that the important value of Schima superba in Kuocang Mountain forest community is significa
