摘　　要：为揭示穗花杉群落在井冈山地区野外生存状态,从而促进其保护和利用,对井冈山地区穗花杉植物群落进行了野外调查和研究与分析。结果表明:穗花杉群落中共有维管植物93种,隶属47科69属;年龄结构显示群落的主要优势种属于稳定型种群,群落总体处于稳定状态;群落的频度指数规律为A>B>C<D<E,与Raunkiaer频度定律相似,E级所占比例较高,说明群落优势种分布较为均匀;井冈山穗花杉群落的多样性指数和均匀度指数不仅高于纬度更高的江西官山穗花杉群落,且高于同纬度且气候条件与江西井冈山差异不大的湖南神坡山穗花杉群落。In order to reveal survival status of Amentotaxus argotaenia in Mount Jingganshan of Jiangxi province,its protection and utilization were promoted,the Amentotaxus argotaenia communities from mount Jingganshan in Jiangxi province was researched and analysed on basis of the field investigation.The results showed that 92species of vascular plants,belonging to 47families and 69genera were found in the A.argotaenia community.The analysis for the age structure of the community showed that the main dominant species were stable populations.And the frequence index of the community was ABCDE,which was similar to the Raunkiaer’s frequency law.Meanwhile,the E ratio was higher in the community,indicating the dominant species were quite even.The diversity and evenness index in the Amentotaxus argotaeniacommunity of mount Jingganshan were not only higher than the community of Guanshan in Jiangxi province,but also higher than that of the community for Shenposhan in Hunan province which latitude and climate conditions had little difference from Mount Jingganshan.
