Abstract: Hainan tropical forests boast extremely high biodiversity, yet large-scale field surveys are highly challenging due to the complex topographical conditions in tropical regions. Large-scale tree quadrat survey data of Hainan tropical forests can provide a scientific basis for the conservation of tropical forest ecosystems. Based on the results of Hainan tropical forest community surveys conducted in 2024, this dataset covers core tropical forest areas in Hainan Province, including Wuzhi Mountain, Bawangling, Diaoluo Mountain, Yinggeling, Jianfengling, and Tongguling. Individual tree surveys were conducted in 120 20 m×20 m quadrats, with Alpha diversity (including Simpson index, Shannon-Wiener index, Species richness, and Pielou evenness index) and Beta diversity (including Sørensen pairwise dissimilarity index, as well as its species turnover and nestedness components) calculated. Having undergone a rigorous data quality control process, this dataset will provide data support for studies on the spatial distribution patterns of plant species composition and diversity in tropical forests.

Key words: spatial distribution, field survey, plant diversity, Species composition, tropical forest
