Abstract: The subtropical mixed evergreen-deciduous broad-leaved forest in karst, where Mulun National Nature Reserve of Guangxi lies, is the best preserved, largest and most representative karst forest of subtropical azonality in the world. The plant resources inventory and research on their biodiversity maintenance mechanism are of great significance to the reconstruction of degraded ecosystem in rocky desertification area. This dataset records and collects the information on species composition in 2014, with subtropical mixed evergreen and deciduous broad-leaved forest in 25 ha forest dynamic monitoring plot of Mulun National Nature Reserve of Guangxi, including scientific name of species, abundance, importance value, leaf habit, and species distribution, containing 227 species in 147 genera, 61 families. This dataset is useful to accumulate scientific data on the dynamic characteristics of the subtropical mixed evergreen-deciduous broad-leaved forest in karst, and to enrich the study of long-term vegetation ecology in China.
