摘　　要：【目的】浙江婺城南山自然保护区在植被分区属于中亚热带常绿阔叶林带,但在其中高海拔区域分布着典型的落叶阔叶林群落,是保护区重点保护的森林生态系统。分析浙江婺城南山1 hm^(2)动态监测样地物种组成及群落结构等特征,为保护区的生物多样性和特色植被资源的保护和动态研究提供参考,也为研究中国亚热带地区落叶阔叶林群落提供基础数据。【方法】基于婺城南山1 hm^(2)固定样地的调查数据,具体分析了该群落物种组成、区系特征、物种多样性指数、群落的径级结构与垂直结构等信息。【结果】(1)样地内共有木本植物39科65属97种(裸子植物3科3属3种,被子植物36科62属94种),其中蔷薇科Rosaceae、杜鹃花科Ericaceae和樟科Lauraceae所占物种数最多;(2)样地内木本植物区系成分中,属级层面温带成分为热带成分的1.63倍,温带成分明显占优势;(3)样地内木本植物总计11 019株,短柄枹栎Quercus serrata、映山红Rhododendron simsii和石灰花楸Sorbus folgneri重要值居前3位,是该群落的优势物种;群落中落叶物种、常绿物种和针叶物种的重要值分别为0.709、0.180和0.111,意味着该群落为典型的落叶阔叶林;(4)样地内植株平均胸径3.66 cm,径级结构呈现倒“J”型,小.径级和较小径级的植物数量占比达95.16%。(5)群落垂直结构上,灌木层、亚冠层和林冠层的植株占比分别为73.79%、23.44%和2.77%,这说明该群落灌木层植株比例较高且林冠层不明显。【结论】浙江婺城南山1 hm^(2)固定样地为典型的落叶阔叶林,群落的物种多样性丰富,植株密度较大,但群落中植株径级总体较小,垂直结构分层不明显,在中亚热带中高海拔地区有一定的代表性。[Objective]The Wucheng Nanshan Nature Reserve in Zhejiang Province belongs to the midsubtropical evergreen broad-leaved forest zone in the vegetation zone,while the typical deciduous broad-leaved forest community is distributed in medium and high altitude area,which is the forest ecosystem under the protection of the Reserve.By analyzing the species composition and community structure characteristics of the 1 hm^(2) forest plot in Nanshan Nature Reserve,this study provides scientific basis for the protection and dynamic research of biodiversity and characteristic vegetation resources in the nature reserve,and also contributes foundational data for the study of deciduous broad-leaved forest communities in the subtropical areas of China.[Method]Based on the survey data from 1 hm^(2) forest plot in the Nanshan Nature Reserve,species composition,flora characteristics,the species diversity index,diameter class structure and vertical structure of the community were analyzed.[Result](1)There were 97 woody species belong to 39 families,65 genera(3 gymnosperms species belong to 3 families and 3 genera,94 angiosperms species belong to 36 families and 62 genera),among which Rosaceae,Ericaceae and Lauraceae accounted for the largest number of species.(2)From a perspective of the flora,the temperate component was approximately 1.63 times as much as the tropical component at the generic level,and the temperate component was dominant.(3)A total of 11019 woody individuals were found in the plot.Quercus serrata,Rhododendron simsii and Sorbus folgneri were the top three dominant species in the community.The important values of the deciduous species,evergreen species and coniferous species were 0.709,0.180 and 0.111,respectively,indicating that the community was a typical deciduous broad-leaved forest.(4)The DBH size-class distribution followed a reverse“J”shape with an average diameter of only 3.66 cm,and the individuals at the minor diameter class accounted for 95.16%of the total population.(5)The proportion of plants in shru
