Abstract:

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.
