中国天然森林土壤碳储量分布图-亚热带森林土壤碳储量分布图（2011-2015）

本数据集包含了我国华南亚热带典型常绿阔叶林0-100cm深度天然森林土壤碳密度分布图（tif格式），数据由野外土壤采集样品，分层取样，层次划分：0-10cm、10-20cm、20-30cm、30-50cm、50-100cm，实验室检测土壤碳含量，汇总计算得出，然后导入ArcGIS软件，叠加我国亚热带区域地理数据融合而成，直观展现我国亚热带常绿阔叶林土壤碳密度的分布情况，区域范围包括经度：18°25-32°45；纬度：100°88-122°27；海拔：3-587米。

This dataset contains a TIFF-format spatial distribution map of soil carbon density in natural forest soils at 0–100 cm depth within the typical subtropical evergreen broad-leaved forests of South China.
The data was generated through field soil sampling with stratified layering: the soil profiles were divided into five sampling layers, specifically 0–10 cm, 10–20 cm, 20–30 cm, 30–50 cm, and 50–100 cm. Soil carbon content was measured via laboratory analysis, and the measured values were aggregated and calculated to derive the soil carbon density dataset. The dataset was then imported into ArcGIS software and integrated with geographic datasets of China's subtropical regions to intuitively illustrate the spatial distribution of soil carbon density in the subtropical evergreen broad-leaved forests of China.
The study area spans a longitude range of 18°25' to 32°45', a latitude range of 100°88' to 122°27', and an elevation range of 3 to 587 meters.
