Abstract: In Geheyan Flatland alongside the Qingjiang River,Cunninghamia lanceolata-Choerospondias axillaris forest is a typical secondary forest,rather complex in composition and structure,and dominated with deciduous broad-leaf species of trees,showing the characteristics of the transitional vegetation section in between mid-subtropics and north-subtropics.The species diversity of the forest in this area is richer than in other secondary forests in the same region,which reveals that the community was disturbed moderately before.Today,the forest has been fairly well reestablished,tending to a mixed forest of evergreen broad-leaf and deciduous broad-leaf trees in succession.
