It analyses theCastanopsis carlesii, Camellia oleifera andSymplocos laurina populations' status and role in theCastanopsis carlesii community basing on the study on the dominant population size structure, survival curve and dynamic. It reveals theCastanopsis carlesi population acts as a main role in the community which maintains the stabilization and renovation of the community. The populations ofCamellia oleifera andSymplocos laurina act as a secondary position. The development and succession dynamics of dominant populations is also discussed. The management method is preliminary drawn out which offers a theoretical basis for the evergreen broad-leaved forest restoration and reconstruction in the lower hilly of the west edge of the Sichuan basin.
