摘　　要：运用生态学方法对后河国家级自然保护区楠木资源进行实地调查,记录楠木种类分布、生境条件及群落数量特征和综合特征等,分析其群落组成、年龄结构、区系特征和生活型谱。结果显示:润楠(Machilus pingii Cheng ex Yang)、山楠(Phoebe chinensis Chun)、桢楠(Phoebe zhennan S.Lee)为3个五峰县新发现记录种;样地1调查群落内共有维管束植物28科32属38种,物种丰富;楠木种群结构不完整,大致呈增长趋势;在高度结构中主林层所占比例最高;分为6个分布区类型和3个变型,且多集中在泛热带分布、北温带和南温带间断分布和世界分布;高位芽植物占绝对优势,其次是地上芽植物和一年生植物。楠木种类较为丰富,但种群数量不大,需要对其进行有效合理的保护。Geographical distribution,habitat conditions,as well as quantitative and comprehensive characteristics of the nanmu population at Houhe Nature Reserve were surveyed.The community composition,population structure,life-form spectrum and areal-types of the forest were analyzed using ecological approaches through field investigation and statistical analysis.Three nanmu varieties,Machilus pingii Cheng ex Yang,Phoebe chinensis Chun and P.zhennan S.Lee,were found for the first time in Wufeng county.The community composition at Sample Lot No.1 was rich in species that included 28 families,32 geniuses,and 38 vascular plants.The population structure of nanmu was generally in a growing trend,but not for all varieties.For plant height,the greatest proportion was in the dominant forest,which was classified into 6 distributions and 3 variant floristic types mostly of pantropic,north temperate and south temperate life-form spectra.Among them,the phaenerophyte plants were most prevalent in the region,followed by chamaephyte and therophyte.Abundant varieties of nanmu were found in thereserve,but limited in quantity.It was recommended that an effective protection program be implemented timely to ensure an appropriate growing population of nanmu.
