Soil physico-chemical properties at two depths in a grassland, shrubland, and forest in the degraded karst region of southwest China.

aMeans for a property (averaged over both soil depths) followed by different letters are significantly different (p<0.05) according to the LSD test.
SWC (%), pH, TN (g kg−1 dry soil), SOC (g kg−1 dry soil), and C:N stand for soil water content, soil pH, soil total nitrogen, soil organic carbon, and ratio of soil organic carbon to total nitrogen, respectively.

同一土壤属性的平均值（以两种土壤深度的均值计）后标注不同字母的组间存在显著差异（p<0.05），该显著性通过最小显著差数法（LSD）检验得出。土壤含水量（SWC，单位：%）、土壤pH值、土壤全氮（TN，单位：g·kg⁻¹干土）、土壤有机碳（SOC，单位：g·kg⁻¹干土）以及碳氮比（C:N），分别对应土壤含水率、土壤酸碱度、土壤总氮、土壤有机碳及土壤有机碳与总氮的比值。中国西南退化喀斯特区域内草地、灌丛与森林生态系统中两种土壤深度下的土壤理化性质数据集。
