摘 要
在全球气候变化的背景下，森林作为关键的碳汇，其管理对碳储量的影响备受关注。本研究以中国亚热带常绿阔叶林为对象，结合长期定位观测和模型模拟，评估了不同经营模式对森林碳储量的影响。研究涉及天然林、人工林和次生林三种类型，通过样地调查、生物量测定和土壤碳分析等技术，获取了2005-2020年森林植被和土壤碳储量的变化数据。结果显示，适度间伐的人工林经营模式显著提高了森林碳储量，年均增长率为2.3%，高于天然林和次生林。土壤有机碳含量初期下降，但随经营年限增加而恢复并超过初始水平。植被碳储量与土壤碳储量之间存在显著正相关。本研究创新地构建了森林经营与碳储量响应关系曲线，揭示了经营强度与碳储量的非线性关系。研究证明了科学合理的森林经营措施能有效提升碳汇功能，为碳中和下的森林管理策略提供了理论和实践指导。这些结果对优化区域森林资源管理和增强生态系统固碳能力具有重要现实意义。

STUDY ON THE INFLUENCE OF FOREST MANAGEMENT ON FOREST CARBON RESERVES
ABSTRACT
In the context of global climate change, the management of forests is the influence of carbon reserves. In this study, the effects of different business models on forest carbon reserves were assessed using Chinese subtropical evergreen broad-leaved forest, combined with long-term localization observation and model simulation. The study involves three types of natural forest, artificial forest and secondary forest, and obtains the change data of forest vegetation and soil carbon reserves from 2005 to 2020 through sample site survey, biomass measurement and soil carbon analysis. The results showed that the plantation management model of moderate thinning significantly increased the forest carbon reserves, with an average annual growth rate of 2.3%, higher than that of natural forests and secondary forests. The soil organic carbon content decreased initially, but recovered with the increase of operating life and exceeded the initial level. A significant positive correlation was observed between vegetation carbon reserves and soil carbon reserves. This study innovatively constructs the response relationship curve between forest management and carbon reserves, and reveals the non-linear relationship between management intensity and carbon reserves. The research proves that scientific and reasonable forest management measures can effectively improve the function of carbon sink, and provide theoretical and practical guidance for the forest management strategy under carbon neutrality. These results have important practical implications for optimizing regional forest resource management and enhancing ecosystem carbon sequestration capacity.
