| 摘要: |
| 森林土壤有机碳在维持全球生态系统碳平衡中发挥重要作用。本研究通过实地调查韩江流域森林土壤，分析土壤样点数据，获取土壤有机碳养分特征及分布格局。结果表明：韩江流域不同土层有机碳含量均值处于9.121~17.702 g/kg之间，不同土层由表层至深层，有机碳含量逐渐降低；空间分布上，在靠近韩江水系平缓区域，森林土壤有机碳含量相对较低，远离水系的高海拔地区森林土壤有机碳含量相对较高。 |

| Abstract: |
| Forest soil organic carbon plays an important role in maintaining global ecosystem carbon balance. The forest soil in Hanjiang watershed was investigated on the spot, the soil sample data were analyzed, and the soil organic carbon nutrient characteristics and distribution pattern were obtained. The results show that the average organic carbon content in different soil layers is between 9.121 g/kg and 17.702 g/kg in Hanjiang River basin. The organic carbon content decreases gradually from the surface layer to the deep layer in different soil layers. In terms of spatial distribution, the forest soil organic carbon content is relatively low in the flat area close to the Hanjiang River, while the forest soil organic carbon content is relatively high in the high altitude area far away from the river. |
