Abstract:
We investigated the species,quantity and growth state of the plants at the wind dama ged slash in 1992,1994,1996,1999 and 2001.On the basis of the investigation into ecological restoration of evergreen broadleaved forest of wind-damaged slash in Jinyun Mountain,we studied the distribution pattern and dynamics of dominant population.The result indicates that seedlings of
Pinus massoniana and
Gordonia acuminata are decreasing,but the seedlings of
Costanopsis carlesii var.spinulosa,Symplocos setchuanenesis and other evergreen broadleaved trees are increasing.Patterns of spatial dispersion of the dominant population are varied with size class,the clumped distribution appears in
Costanopsis carlesii var.spinulosa and Symplocos setchuanenesis,Possion distribution in Ⅰ and Ⅱ class of
Gordonia acuminata after 1996,before 1996,it appeared clumped distribution.Ⅲ and Ⅳ class in
Pinus massoniana and
Gordonia acuminata are appearing possion distribution.The age structure of
Pinus massoniana and
Gordonia acuminata appeared declining,and
Costanopsis carlesii var.spinulosa,Symplocos setchuanenesis appeared growing.
