Abstract: With the rapid development of society, the scale of plantation is continuously expanding. How to effectively carry out the management of plantation and evaluate the functions of the ecosystem is a long-term research topic. Heshan Hilly Comprehensive Open Experimental Station of the Chinese Academy of Sciences (hereafter referred to as Heshan Station) was established in 1984, focusing on "plantation ecosystems" as the research object, adhering to the long-term observation standards of CERN, and conducting long-term community dynamics observation of the main plantation types in the South China region, accumulating long-term data. This dataset includes the species composition and community characteristics data of the long-term monitoring plot of Acacia mangium plantation at Heshan Station from 2005 to 2015, as well as detailed information on the construction process of the dataset., It is expected to provide important data support for plantation management and ecosystem function evaluation.

Key words: Heshan Station, Acacia mangium plantation, species composition, community characteristics
