摘要:
为探究江苏杨树人工林碳储量本底，该研究对苏南丘陵、苏北沿海、苏北黄泛平原3个杨树种植重点区域的杨树人工林碳密度进行了调查，探讨了不同区域、不同林龄杨树人工林碳密度的分布特征，并分析了杨树人工林碳密度与土壤理化性质的相关性。结果表明：（1）杨树人工林成熟林碳密度在苏南丘陵区和苏北黄泛平原区之间存在显著差异(P<0.05)；在苏北沿海地区和苏北黄泛平原区，各区幼龄林碳密度与成熟林碳密度之间均存在显著性差异(P<0.05)；而苏北黄泛平原区中龄林和成熟林中之间也具有显著差异(P<0.05)；各区域杨树人工林碳密度随着林龄的增加而显著增大。（2）杨树人工林碳密度与土壤可溶性有机碳(DOC)以及pH之间均存在显著的正相关关系。江苏杨树人工林的碳密度与分布区域、林龄结构、土壤性质等都有一定的相关性，在杨树人工林的后续管理中，应依据不同区域的立地特征和林分状况，科学优化管理措施，以提升江苏杨树人工林的固碳能力。
Abstract:
To investigate the baseline carbon storage of poplar plantations in Jiangsu Province, we examined the carbon density distribution characteristics of poplar plantations in three typical cultivation regions: the Southern Hilly Region, Northern Coastal Area, and Northern Yellow River Flood Plain. The correlations between carbon density and soil physicochemical properties were analyzed. The results demonstrated that: (1) Significant differences (P<0.05) in mature stand carbon density were observed between the Southern Hilly Region and Northern Yellow River Flood Plain. In both the Northern Coastal Area and Northern Yellow River Flood Plain significant differences (P<0.05) exhibited in carbon density between young and mature stands. Furthermore, in the Northern Yellow River Flood Plain, significant differences (P<0.05) showed between middle-aged and mature stands. Carbon density significantly increased with stand age across all regions. (2) Significant positive correlations were identified between poplar plantation carbon density and both soil dissolved organic carbon (DOC) and pH. The findings suggest that carbon density in Jiangsu’s poplar plantation demonstrates regional specificity and shows relationships with stand age structure and soil properties. For enhancing carbon sequestration capacity, future management strategies should be scientifically optimized, and implemented according to site characteristics and stand conditions across different regions.
