Abstract:

Ailaoshan is located in the central Yunnan region, affected by the southwest monsoon. Mid-mountain moist evergreen broadleaf forest vegetation is distributed within the altitude range of 2 000-2 600 m. Establishment of a long-term monitoring plot in mid-mountain moist evergreen broadleaf forest in Ailaoshan (Plot No.: ALFZH01AC0_01) for long-term ecological monitoring has important scientific value. This dataset integrates the data of species composition and community characteristics of the forest plant community, including the tree layer, shrub layer, herbaceous layer, inter-layer epiphyte (parasitic) and interlayer vines by utilizing monitoring data from 2005 and 2010 within the plot. A total of 174 species were recorded, belonging to 70 families and 129 genera. The top 5 families with the largest number of species were Liliaceae (10 species), Rosaceae (9 species), Hydrosauridae (9 species), Lauraceae (6 species) and Theaceae (6 species). The first five genera are Ilex (5 species), Symplocos (5 species), Elatostema (4 species), Impatiens (3 species) and Carex (3 species). The main plant life forms were herbaceous (56 species), accounting for 32.18%; there were 41 species of shrubs, accounting for 23.56%; there were 28 species of trees, accounting for 16.09%. The floristic components of the plot species were mainly tropical Asian species, accounting for 51.72%. According to the Chinese vegetation classification system, the vegetation in the plot were classified as Castanopsis wattii + Schima noronhae + Machilus gamblei - Fargesia wuliangshanensis - Plagiogyria pycnophylla Evergreen Broadleaf Forest.

Key words: mid-mountain moist evergreen broadleaf forest, Ailaoshan, long-term monitoring plot, species composition, community characteristics
