2026-07-16 A dataset of arbor diversity and soil physicochemical properties in Hainan tropical forests doi:10.57760/sciencedb.31669 en Hainan tropical forests are biodiversity hotspots, yet their complex terrain poses difficulties for extensive ecological monitoring. This dataset presents the results of a large-scale field survey of tree communities conducted in 2024 across Hainan key tropical forest areas: Wuzhi Mountain, Bawangling, Diaoluo Mountain, Yinggeling, Jianfengling, and Tongguling. The survey established 120 plots (20 m × 20 m) to record individual tree attributes, including Chinese and Latin species names, diameter at breast height, tree height, crown dimensions (major and minor axes), and abundance. The dataset further includes calculated values for α diversity (Simpson, Shannon-Wiener, Species richness, and Pielou evenness indices) and β diversity (Sørensen pairwise dissimilarity, as well as Bray-Curtis and Jaccard indices). All data have undergone strict quality control procedures to ensure accuracy, providing a valuable resource for investigating spatial distribution patterns of plant composition and diversity in tropical forest ecosystems. spatial distribution; field survey; plant diversity; species composition; tropical forest yang mei hua Zhang Zijia Qiao Dong Feng Junna Pang Zijie Qian Long Liu Zhihui Cai Nana Hu Zhongmin Yang Guojiao RESTRICTED dataset Science Data Bank
