Distribution Pattern and Dynamics of Dominant Population in the Progression of Ecological Restoration of Evergreen Broadleaved Forest after Wind-damage in Jinyun Mountain

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.
