Abstract:

The Cryptocarya concinna,Lindera chunii community in Dinghu Mountain is one of the types of evergreen broadleaf forest in low subtropical area of China. The specific composition and structural feature in an experimental plot of 1300 m2 of the community were investigated. The community can be divided into arbor layer including 3 sublayers,shrub layer and hero layer clearly,the tallest tree was 21 m high.In the plot there were 109 species of vascular plants,belonging to 61 families 91 genera,most of which belong to tropical genera.There were 42 species of plants in arbor layer,30 species in shrub layer and 21 spacies in herb layer as well as 12 species of liana and 4 species of epiphytes in the plot.It is such a community with complex structure and species diversity.The physiognomy of the community is evergreen all the year round.The life form of plant in the community is phaenetophytes,no cryptophyte,with simple leaf and mesophylls for most trees.Those reflect the climatic characteristics of high temperature and humidity in low subtropical area.
