Abstract

Mingling of dominant plant populations in an evergreen broadleaf forest,one of the most important plant types in the Mount Tianmu National Nature Reserve of Zhejiang Province,were studied to supply a theoretical basis for evergreen broadleaf forest protection,restoration,and reconstruction. A typical plot in the reserve,100 m×100 m,was surveyed for tree diameter at breast height(DBH) above 5 cm with Total Station(Leica TCR702Xrange) equipmentused to measure tree coordinates. Also,dominant plant populations were determined using the Dominance Index with edge correction applied and the mingling index calculated for tree species diversity. Results showed that the dominant plant populations of evergreen broadleaf tree species(Cyclobalanopsis gracilis,Cyclobalanopsis glauca,and Lithocarpus brevicaudatus) exhibited diverse and dominant species characteristics. The average mingling index for the plots was 0.505 1; while the evergreen broadleaf tree species mingling index was 0.483 6, and the non-evergreen broadleaf species mingling index was 0.582 3. Overall,these tree species maintained the evergreen broadleaf forest biodiversity.In addition,as dbh increased,the mingling index increased. Since C. gracilis,C. glauca,and L. brevicaudatus predominantly reproduced through sprouting,the mingling index was low. This study showed that these evergreen broadleaf tree species showed moderate mixing.
