Population characteristics of the medicinal plants in Castanopsis fissa communities at different sites

Population characteristics of the main medicinal plants in Castanopsis fissa communities protected for 28 years at the best and ordinary fertile sites and protected for 8 years at the less fertile site were analyzed.At the best fertile site,the main medicinal plants in arbor layers were composed by Elaevcarpus sylvestris,Itea chinensis and Heteropanax brevipedicellatus,et al;Itea chinensis,Iiex pubescents and Elaevcarpus sylvestris consisted of the main medicinal plants in shrub layers,and the main medicinal plants in herb layers were composed by Cibotium barometz,Maesa japonica,Pteris aguium,et al.At the ordinary fertile site,the main medicinal plants in arbor layers were composed by Elaevcarpus sylvestris,Itea chinensis and Heteropanax brevipedicellatus,et al;Itea chinensis,Iiex pubescents and Elaevcarpus sylvestris consisted of the main medicinal plants in shrub layers,and the main medicinal plants in herb layers were composed by Cibotium barometz,Maesa japonica and Pteris aguium,et al.At the less fertile site,the main medicinal plants in arbor layers were composed by Cunninghamia lanceolata,Rhododendron simsii,Elaevcarpus sylvestris,et al;the main medicinal plants in shrub layers were composed by Dicranopteris dichotoma,Clerodendron fortunatum and Ardisia crenata,et al,and the main medicinal plants in herb layers were composed by Adiantum flabellulatum,Iiex pubescents and Dicranopteris dichotoma,et al.
