摘　　要：研究了发现于湖州市埭溪的古樟树Cinnamomum camphora林的生境、植物区系、群落学特征和保护价值等。结果表明:该古树群地处浙江北部水网平原,区系组成复杂,共有维管植物219种,隶属于70科166属;地理成分多样,以温带成分略占优势。具有典型的常绿阔叶林外貌;生活型以高位芽植物居首位,次为地面芽植物和1年生植物。垂直结构复杂,成层现象明显,可分为乔木层、灌木层、草本层和层间层。优势种主要为樟树,朴树Celtis sinensis,糙叶树Aphananthe aspera,榉树Zelkova schneideriana,其中樟树的龄级结构属于增长型趋向稳定型。群落生物多样性丰富,具有十分重要的生态、景观、科研和文化价值。The eco-environment, flora, community features, and conservation value of an old-growth community dominated by Cinnamomum camphora in Daixi Town, Huzhou, Zhejiang Province were studied. Results indicated that this community located on a flatland with water networks in the northern part of Zhejiang Province had a complex and diversified floristic composition of 219 vascular plant species belonging to 70 families and 166 genera with temperate elements predominating. The C. camphora dominated community had the classic appearance of an evergreen broadleaf forest with the dominant life forms classes being from Phanerophytes followed by Hemicryptophytes and Therophytes. The community vertical structure was complex with stratification divided into tree, shrub, and herb layers along with interlayers. Dominant species were C.camphora, Celtis sinensis, Aphananthe aspera, and Zelkova scheioleriana. The C. camphora age structure belonged to the growth type and tended to be stable. Overall, the community was rich in biodiversity and valuable for its ecology, landscape, science, research, and cultural opportunities.
