摘　　要：对浙江铜铃山国家森林公园次生常绿阔叶林和针阔混交林乔木群落的物种组成、径级结构、优势种种群存活曲线及稳定性进行了调查和研究。结果表明:次生常绿阔叶林乔木层包含31科51属84种,针阔混交林乔木层包含26科48属76种;2个林型的优势种明显,次生常绿阔叶林重要值排名前5的物种为木荷(Schima superba Gardn.et Champ.)、甜槠〔Castanopsis eyrei(Champ.)Tutch.〕、短尾柯〔Lithocarpus brevicaudatus(Skan)Hayata〕、马银花〔Rhododendron ovatum(Lindl.)Planch.ex Maxim.〕和尖连蕊茶〔Camellia cuspidata(Kochs)Wright ex Gard.〕,针阔混交林重要值排名前5的物种为杉木〔Cunninghamia lanceolata(Lamb.)Hook.〕、木荷、马尾松(Pinus massoniana Lamb.)、黄山松(Pinus taiwanensis Hayata)和柳杉(Cryptomeria fortunei Hooibrenk ex Otto et Dietr.)。次生常绿阔叶林乔木层中木荷、甜槠和短尾柯种群径级分布均呈倒“J”型,存活曲线均为直线型,属于稳定型种群;红楠(Machilus thunbergii Sieb.et Zucc.)种群径级分布接近“L”型,存活曲线为“凹”型,属增长型种群。针阔混交林乔木层中杉木种群径级分布呈“L”型,存活曲线为“凹”型,属于增长型种群;木荷种群径级分布呈倒“J”型,存活曲线为直线型,属于稳定型种群;黄山松和马尾松种群径级分布接近正态分布,存活曲线均呈“凸”型,属于衰退型种群。MGodron群落稳定性分析结果表明:铜铃山国家森林公园2种林型均处于不稳定状态。CCA分析结果显示:海拔是影响这2个林型的主要环境因子。综合研究结果显示:铜铃山国家森林公园次生常绿阔叶林和针阔混交林处于相对稳定的演替中期,未达到稳定的顶极群落状态。Species composition,diameter class structure,survival curve of populations of dominant species,and stability of arbor community of secondary evergreen broad-leaved forest and coniferous and broad-leaved mixed forest in Tonglingshan National Forest Park of Zhejiang Province were surveyed and studied.The results show that there are 84 species in 51 genera belonging to 31 families in arbor layer of secondary evergreen broad-leaved forest,and 76 species in 48 genera belonging to 26 families in arbor layer of coniferous and broad-leaved mixed forest.The dominant species of two forest types were obvious.Top five species based on important value in secondary evergreen broad-leaved forest are Schima superba Gardn.et Champ.,Castanopsis eyrei(Champ.)Tutch.,Lithocarpus brevicaudatus(Skan)Hayata,Rhododendron ovatum(Lindl.)Planch.ex Maxim.,and Camellia cuspidata(Kochs)Wright ex Gard.,and those in coniferous and broad-leaved mixed forest are Cunninghamia lanceolata(Lamb.)Hook.,S.superba,Pinus massoniana Lamb.,Pinus taiwanensis Hayata,and Cryptomeria fortunei Hooibrenk ex Otto et Dietr.Diameter class distributions of S.superba,C.eyrei,and L.brevicaudatus populations in arbor layer of secondary evergreen broad-leaved forest exhibit inverted J-shape,and their survival curves are linear type,which belong to stable type;that of Machilus thunbergii Sieb.et Zucc.population is close to L-shape,and its survival curve is concave type,which belongs to increasing type.Diameter class distribution of C.lanceolata population in arbor layer of coniferous and broad-leaved mixed forest shows L-shape,and its survival curve is concave type,which belongs to increasing type;that of S.superba population shows inverted J-shape,and its survival curve is linear type,which belongs to stable type;those of P.taiwanensis and P.massoniana populations are close to normal distribution,and their survival curves are convex type,which belong to declining type.The result of M-Godron analysis on community stability shows that the two forest types in Tonglingshan N
