Linking land use change to soil carbon quality and management indices: Insights from labile SOC dynamics

“This dataset contains raw and processed data used to evaluate soil organic carbon fractions, carbon management index (CMI), and key biological indicators under different land‑use types. The data include measurements of SOC, labile carbon pools, microbial biomass carbon. These files were used to perform statistical analyses and generate the figures and tables presented in the manuscript.”本数据集包含用于评估不同土地利用类型下土壤有机碳组分、碳管理指数（Carbon Management Index, CMI）以及关键生物学指标的原始与处理后数据。数据涵盖土壤有机碳（Soil Organic Carbon, SOC）、活性碳库以及微生物生物量碳的测定结果。这些数据文件被用于开展统计分析，并生成论文中呈现的图表与表格。
