Abstract:

The ecological “green-core” area of Changzhutan urban cluster is located in the center of red soil hilly region of Southern China, and the northern vegetation sub-zone of mid-subtropical evergreen broad-leaved forests. In this area, the vegetation is dominated by secondary forests, and the vegetation types are diverse. It is representative of the current vegetation in red soil hilly region of South China, and hance can provide a good platform for the research of regional vegetation succession dynamics and vegetation restoration. We set up 50 plots with a unified and standardized method, and then the species composition, quantitative characteristics, and habitat information of the main vegetation types in the area were investigated. The importance values of species in the tree layer, shrub layer and herb layer were calculated, and the vegetation type of each community were identified and named according to the compilation and research standard of Vegegraphy of China. The community species composition and characteristics were described, and the original data of 50 plots divided into 10 vegetation formations, 22 alliances and 33 associations were provided, including 43 forest plots, 5 shrub plots, 1 grassland plot and 1 swamp plot.

Key words: vegetation classification, species composition, vegetation restoration, red soil hilly region of Southern China, ecological green-core area of Changzhutan urban cluster
