| 森林土壤有机碳是森林碳库的重要组成部分。研究通过大范围采集连州市森林土壤分层样本
并测定有机碳含量，通过空间分析方法，进而揭示连州市林地土壤有机碳含量的空间分布格局特征。结
果表明：连州市森林土壤有机碳平均含量分别为 13.05±7.01 g/kg（I-F-1），11.81±6.01 g/kg（I-F-2），
11.30±5.86 g/kg（I-F-3）。土壤有机碳含量在垂直空间上随着土层的加深而降低，但土层间差异不显著。
在空间分布上，有机碳含量在连州市东南部区域为高值区，中北部为低值区域。这可能是地形、水系等
原因造成的。 |

| Abstract: |
| Forest soil organic carbon is an important part of the forest carbon pool. This study collected
stratified forest soil samples and measured organic carbon content in a wide range of Lianzhou city, and then
revealed the spatial distribution pattern of soil organic carbon content in Lianzhou city through the spatial analysis
method. The results showed that the average content of forest soil organic carbon in Lianzhou was 13.05±7.01
g/kg (I-F-1), 11.81±6.01 g/kg (I-F-2), and 11.30±5.86 g/kg (I-F-3), respectively. Soil organic carbon content
in vertical space decreased with the deepening of the soil layer, but the difference between soil layers was not
signi?cant. In terms of spatial distribution, the content of organic carbon in the southeastern parts of Lianzhou is
a high-value area, and the content of organic carbon in the central and northern part of Lianzhou is a low-value
area. This may be due to terrain, water system, and other reasons. The results of this study are helpful in clearly
understanding the forest soil site conditions in Lianzhou city and provide a basis for more reasonable forest
cultivation. |
