摘　　要： 为了了解乡土阔叶树种的生物学特性,通过测定林木地径、树高和冠幅的方法,对樟树、大叶女贞、观光木、山杜英、乳源木莲和乐昌含笑等6种阔叶林的生长进行研究。结果表明:林木地径、树高和冠幅生长均呈现樟树、山杜英、乐昌含笑快,大叶女贞、观光木、乳源木莲慢的格局。聚类分析表明,樟树、山杜英、乐昌含笑为速生树种,其平均地径年生长量范围为2.2～2.5cm,平均树高年生长量范围为0.9～1.1m,平均冠幅年生长量范围为0.5～0.6m。大叶女贞、观光木、乳源木莲为生长速度慢的树种,平均地径年生长量范围为0.7～1.1cm,平均树高年生长量范围为0.3～0.5m,平均冠幅年生长量范围为0.1～0.3m。樟树、山杜英、乐昌含笑是适宜推广的乡土阔叶树种。 In order to understand biological characteristics of local broadleaved trees,the study on growth characteristics of broadleaved stands of Cinnamomum camphora,Ligustrum lucidum,Tsoongiodendron odorum,Elaeocarpus sylvestris,Manglietia yuyuanensisand,Michelia chapensis were conducted from 2005 to 2008,using methods of determining mean ground diameter,tree height and crown width.The results were listed as follows：the growth of C.camphora,E.sylvestris and M.chapensis was fast,whereas the growth of L.lucidum,T.odorum and M.yuyuanensis was slow.Cluster analysis indicated that C.camphora,E.sylvestris and M.chapensis were fast-growth tree species with increment ranges of mean ground diameter from 2.2 to 2.5 cm,mean tree height from 0.9 to 1.1 m and mean crown width from 0.5 to 0.6 m,whereas L.lucidum,T.odorum and M.yuyuanensis were slow-growth tree species with increment ranges of mean ground diameter from 0.7 to 1.1 cm,mean tree height from 0.3 to 0.5 m and mean crown width from 0.1 to 0.3 m.The C.camphora,E.sylvestris and M.chapensis are the tree species which are suitable to popularize.
