不同演替程度下马尾松人工林生物多样性对生物量的影响实验数据集

2018年湖北省荆门市京山县太子山林场马尾松人工林样地调查及实验分析数据，由课题组实测。所有样地共计55，每个样地设置20m×20m样方，并记录坡度、坡向、林龄，胸径≥5cm的木本植物每木检尺。实验分析针对样地内主要优势树种，计算了包括马尾松、麻栎、樟树、柏木、杉木、阔叶树种的生物量，以及样地Shannon_Wiener指数、Simpson指数、Pielou指数、功能丰富度（FRic）、功能均匀度（FEve）、功能离散度（FDis）、功能多样性（RaoQ）、林分密度。所有数据整理为样地每木表和数据汇总表。

This dataset comprises field survey and experimental analysis data of Pinus massoniana plantation plots in Taishan Forest Farm, Jingshan County, Jingmen City, Hubei Province, collected in 2018, which was measured and compiled by the research team. A total of 55 plots were established, each with a 20m×20m quadrat. Slope gradient, slope aspect and stand age were recorded, and a tree-by-tree census was conducted for woody plants with diameter at breast height (DBH) ≥ 5 cm. For the dominant tree species within the plots, experimental analyses were performed to calculate the biomass of Pinus massoniana, Quercus acutissima, Cinnamomum camphora, Cupressus funebris, Cunninghamia lanceolata and broad-leaved tree species, as well as the plot-level Shannon-Wiener Index, Simpson Index, Pielou Index, Functional Richness (FRic), Functional Evenness (FEve), Functional Dispersion (FDis), Functional Diversity (RaoQ) and stand density. All data were organized into individual tree tables for each plot and a comprehensive data summary table.
