摘　　要：【目的】研究福建省牙梳山香果树生境群落特征和物种多样性,为香果树野生群落保护提供依据。【方法】采用样地法获取香果树生境群落信息,测定并分析优势种的重要值、多样性指数、径级结构、高度结构和群落稳定性。【结果】牙梳山香果树生境群落共有植物64科93属143种,主要由樟科、蔷薇科、壳斗科、茜草科和鳞毛蕨科物种组成,其优势种为紫楠、粗糠柴、杜茎山和翠云草,香果树为乔木层的重要组成部分。各层次物种多样性指数表现为乔木层(2.121)>草本层(1.976)>灌木层(1.437)。香果树种群缺乏中层径级,断层严重,且稳定性较低。【结论】香果树生境群落各层次群落稳定性均较低,建议加强环境监测,并适当采取人为保护措施。【Objective】This study investigated the community characteristics and species diversity of Emmenopterys henryi habitat in Yashu Mountain,Fujian Province,to provide a basis for the conservation of wild E.henryi communities.【Method】Sample plot method was used to obtain the E.henryi habitat information,and the importance values of dominant species,diversity index,diameter structure,height structure and community stability were determined and analysed.【Result】The E.henryi habitat community in Yashu Mountain harbored 143 plant species,which belonged to 93 genera and 64 families.The dominant families were made up by Lauraceae,Rosaceae,Fagaceae,Rubiaceae and Dryopteridaceae,with Phoebe sheareri,Mallotus philippensis,Maesa japonica and Selaginella uncinata as the dominant species,and E.henryi was an important part of the arbor layer.The plant diversity index of each layer followed the order of arbor layer(2.121)>herb layer(1.976)>shrub layer(1.437).The E.henryi population were seriously lack of middle diameter class,and featured by low stability.【Conclusion】The community stability of E.henryi habitat was low at all layers,therefore strengthened environmental monitoring and appropriate anthropogenic protection measures were highly recommended.
