| 摘要: |
| 以清远市针叶林土壤为研究对象，采用专题样点与空间随机样点布设相结合，布点 134 个，
测定 0~80 cm 土层有机碳含量，并用空间插值法分析其含量分布特征。结果显示：清远市针叶林 0~20 cm
层土壤有机碳含量最高，随土层厚度增加，有机碳含量大致呈递减趋势，表层土壤有机碳含量平均值为
13.99 g · kg-1；同一土层不同区域有机碳含量存在差异，西北部有机碳含量相对较低，中部和东南部相对
较高。 |

| Abstract: |
| Exploring the distribution of soil organic carbon in coniferous forests is of great significance to
soil carbon cycle research and scientific management of coniferous forests. This study took coniferous forests as
the research object, measured the soil organic carbon content, and used spatial interpolation to analyze its content
distribution. The results showed that the organic carbon content in the topsoil of coniferous forest in Qingyuan
city was the highest, and the organic carbon content generally decreased with the increase of soil thickness. The
organic carbon content in the topsoil was about 13.99 g · kg-1.There are differences in content, with relatively low
organic carbon content in the northwest and relatively high levels in the center and southeast. |
