Abstract: Alniphyllum fortunei forest is a seral stage of evergreen broadlleaf forest sere, mainly occurs in red and yellow soil mountain of eastern central subtropics below 130.0m at elevation.It belongs to a community type of subtcopical deciduous broadleaf forest.3 Plant Association Classes and 13 Plant Associations are described as follows: I Young growth of Ahniphyllum fortunei with single tree layer 1.Alniphyllum fortunei-Eurya nitida -Miscanthus floridulus Association, 2.Alniphyllum fortunei-Itea chinensis-Woodwardia japonica Association, Ⅱ Middle age forest of Alniphyllum fortunei with two tree layers 3.Alniphyllum fortunei-Eurya loquiana-Maesa japonica-Woodwardia japonica Association, 4.Alniphyllum fortunei+Liquidambar formosana-Eurya impressinervis-Masea japonica-Woodwardia japonica Association, 5.Alniphyllum fortunei+carpinus fargesii-castanopsis carlesii-Masea japonica-Woodwardia japonica Association, Ⅲ Mature forest of Alniphyllum fortunei with three tree layers 6. Alniphyllum fortunei+Betula luminifera-Clethra kaipoensis -Blastus cochinchinensis-Woodwardia japonica Association, 7.Alniphyllum fortunei-Cinnamomum parthenoxylon-Ilex asprella-Woodwardia japonica Association, 8.Aliphyllum fortunei+Liquidambar formosana-Pseudosasa amabilis-Ilex asprella-Woodwardia japonica+Blechnum orientale Association, 9.Alniphyllum fortunei-Itea chinensis-Lasianthus, acuminatissima-woodwardia japonica Association 10.Alniphyllum fortunei-Eurya impressinervis-Blastus cochinchinensis-Woodwardia japonica Association, 11.Alniphyllum fortunei-Daphniphyllum glaucescens-Hydrangea paniculata-phyllagathis cavaleriei Association, 12.Alniphyllum fortunei-Schima argentea-Lasianthus glaberrima-Woodwardia japonica Association, 13.Alniphyllum fortunei+Schima argentea-Eurya impressinervis-Maesa japonica-Woodwardia japonica Association. Its successional trend toward recovering evergreen broadleaf forest can be fully proved through information analysis of community physiognomy, structure and species composition change between 13 Associations.
