DATASET: Climatic and edaphic drivers of soil organic carbon and pyrogenic carbon stocks across elevation and disturbance gradients in Colombian Andean forests

The dataset contains information on: entry variables in column: soil pyrogenic carbon PyC (Org) (Mg/ha), PyC (mg cm-3), NDVI(Nrmalized Difference Vegetation Index), Slope (degrees), AMT (Annual Mean Temperature in degrees Celsius), AP (Annual precipitation in mm), pH ( measure of soil acidity or alkalinity), P_available ( phosphorus available, in mg/kg), Tot_ p (Total phosphorus, in mg/kg), sand (%), clay (%), silt (%), Ca_ex (exchangeable calcium, in meq/100g), Mg_ex (exchangeable magnesium, in meq/100g), K_ex (exchangeable potassium, in meq/100g), and Na_ex (exchangeable sodium, in meq/100g). Disturbance (entries by row: low, médium, high, very high); Zone (entries by row: high Andes (h_And), médium Andes (m_And), and low Andes (l_And); and Depth (cm), entries by row: 0-5 cm, 20-30 cm, 30-50 cm and 50-100 cm本数据集包含如下列输入变量信息：土壤热解碳（soil pyrogenic carbon, PyC）相关指标：PyC(Org)（单位：Mg/ha）、PyC（单位：mg·cm⁻³）；归一化差分植被指数（Normalized Difference Vegetation Index, NDVI）；坡度（Slope，单位：°）；年平均气温（Annual Mean Temperature, AMT，单位：℃）；年降水量（Annual Precipitation, AP，单位：mm）；土壤pH值（表征土壤酸碱程度）；有效磷（phosphorus available, P_available，单位：mg/kg）；全磷（Total phosphorus, Tot_P，单位：mg/kg）；砂粒占比（%）、黏粒占比（%）、粉粒占比（%）；交换性钙（exchangeable calcium, Ca_ex，单位：meq/100g）、交换性镁（exchangeable magnesium, Mg_ex，单位：meq/100g）、交换性钾（exchangeable potassium, K_ex，单位：meq/100g）及交换性钠（exchangeable sodium, Na_ex，单位：meq/100g）。此外还包含三类分类变量：干扰程度（Disturbance），其行取值依次为低、中、高、极高（原文存在拼写笔误“médium”，应为“medium”）；安第斯山区海拔带（Zone），其行取值依次为高海拔安第斯山区（high Andes, h_And）、中海拔安第斯山区（medium Andes, m_And）、低海拔安第斯山区（low Andes, l_And）；土层深度（Depth，单位：cm），其行取值依次为0~5 cm、20~30 cm、30~50 cm及50~100 cm。
