摘 要
本研究以我国南方重要造林树种马尾松为研究对象,针对当前森林碳汇功能评估精度不足、经营策略缺乏针对性等问题,采用样地调查与模型模拟相结合的方法,系统评估了不同林龄马尾松林的碳储量动态变化及其影响因素。研究基于改进的CBM-CFS3模型,构建了马尾松林碳汇潜力评估体系,并通过情景模拟分析了不同经营措施对碳汇功能的影响机制。结果表明:成熟马尾松林单位面积碳储量可达120-150 t/ha,其中乔木层占比超过60%;通过优化密度调控和轮伐期设置,可使马尾松林年均碳汇量提升15%-20%;基于碳汇效益最大化的最优经营方案显示,将轮伐期延长至35年、保留密度控制在1200-1500株/ha时,可实现生态效益与经济效益的最佳平衡。本研究的创新点在于建立了适用于亚热带地区的马尾松林碳汇动态评估模型,提出了兼顾碳汇功能和木材生产的可持续经营策略,为区域森林生态系统服务功能提升提供了科学依据和技术支撑。研究成果对于完善森林碳汇计量方法、指导林业生产实践具有重要的理论价值和现实意义。

ABSTRACT
This study focuses on Pinus massoniana, a significant afforestation species in southern China, addressing the current limitations in the accuracy of forest carbon sink function assessment and the lack of targeted management strategies. By combining plot surveys with model simulations, the research systematically evaluates the dynamic changes in carbon storage and their influencing factors across different age classes of Pinus massoniana forests. Based on an improved CBM-CFS3 model, a carbon sink potential assessment system for Pinus massoniana forests was developed, and scenario simulations were conducted to analyze the impact mechanisms of various management measures on carbon sink functions. The results indicate that mature Pinus massoniana forests can achieve a carbon storage of 120-150 t/ha, with the tree layer accounting for over 60% of the total. Optimizing density regulation and rotation period settings can increase the annual carbon sequestration by 15%-20%. The optimal management strategy for maximizing carbon sink benefits suggests that extending the rotation period to 35 years and maintaining a stand density of 1200-1500 trees/ha can achieve the best balance between ecological and economic benefits. The innovation of this study lies in establishing a dynamic carbon sink assessment model suitable for subtropical regions and proposing sustainable management strategies that integrate carbon sink functions with timber production, providing scientific basis and technical support for enhancing regional forest ecosystem services. The findings hold significant theoretical value and practical implications for improving forest carbon sink measurement methods and guiding forestry production practices.
