Model Fit Statistics for Urban Tree Biomass Equations in Shihezi City

This dataset provides the statistical diagnostics for species-specific biomass allometric equations developed for 14 urban tree species in Shihezi City, an arid region of northwestern China. The dataset includes the coefficient of determination (R²), root mean square error (RMSE), standard errors of model parameters, and sample sizes used for model fitting. These diagnostics evaluate the performance and reliability of the biomass equations reported in the associated manuscript. The dataset serves as supplementary material supporting transparency and reproducibility in urban tree biomass and carbon estimation studies.

本数据集针对中国西北干旱区石河子市的14种城市树木物种，提供了为其构建的物种特异性生物量异速生长方程（species-specific biomass allometric equation）的统计诊断指标。数据集包含决定系数（coefficient of determination, R²）、均方根误差（root mean square error, RMSE）、模型参数标准误以及模型拟合所用的样本量。这些统计诊断指标可用于评估相关研究论文中报道的生物量方程的性能与可靠性。本数据集作为补充材料，为城市树木生物量与碳储量估算研究的透明度提升及可重复性保障提供支撑。
