The characteristics of synecology, population ecology and physio-ecology of main tree species Quercus fabri, Pinus massoniana, Castanopsis sclerophylla, Lithocarpus glaber, Schima superba and C. fargesii of evergreen broadleaved forest in Tiantong National Forest Park, Zhejiang Province were studied by comparative method. The successional process was clarified through the comparative studies of the synecological characteristics of these main tree species, the individual plant structure and renewability were discussed by comparative study of population ecological characteristics of main trees' populations, and the mechanism of replacement with each other of these main tree species was open out by comparative study of physio-ecological characteristics of these main trees. Based on the study of comparative ecology of the main dominant evergreen broadleaved forest series, the successional stage and direction and its management could be determined, and the theoretical basis for the planning and management of forest production, and the restoration, reconstruction, and exploiting under artificial disturbance could be offered.
