摘要
观光木属于珍稀植物，被列为我国Ⅱ级保护植物．观光木林是福建省建瓯万木林自然保护区的主要常绿阔叶林类型之一．本文通过无样地法群落调查，对其主要树种进行了重要值测定，并对群落的结构和动态进行了分析和研究．研究表明本群落是以木兰科等为主的常绿阔叶林，其优势种为观光木、尖叶水丝梨、拉氏栲．观光木目前林中幼苗很少，群落处于衰退之中．因此，本文还对观光木林的保护和研究提出了建议和措施．
Tsoongiodendron odorum forest is one of the main forest types in Wanmulin Nture Reserve,located in the mid-subtropical region in China. Analysis of structure and dynamic indicated that the community was dominated by some species of Magnolia family.The tree layer of the forest can be divided into two sublapers.Tsooglodendron odorum,25～33 metres in height,dominates the first sublayer.Sycopsis dunnii,Litses Subcorlacea and Sloanea sinensis dominate the second sublayer.The shrub layer,altogether 33 species,is less than 3 metres in height and dominated by Litsea subcoriacea, Maesa Japonica,Engelhardtia fenzelii and Cinnamomum Chekiangense etc, In the herb layer are only two fern species. Few Tsoongioderdron odorum seedlings under the canopy suggest its dominance in the fores will decrease as the succession proceeds.
