摘要:

森林在全球碳循环中发挥着重要作用，森林碳汇是陆地碳汇的重要组成部分，其研究的知识领域在国际社会中已较为成熟。以Web of Science中1990-2021年4973篇相关的文献为研究对象，运用文献计量工具CiteSpace绘制文献共被引和关键词共现网络知识图谱，以此清楚分析森林碳汇研究的发展趋势。研究发现：（1）森林碳汇研究的发文量持续增长，文献数量的变化趋势证明森林碳汇仍是国内外的研究热点。（2）森林碳汇研究主线变化从运用大量方法测量森林碳平衡，到对森林碳汇稳定区域估计的理论归纳，再到将理论用于实践并全面实现对全球碳汇规模的监控。阶段的热点问题从森林是否为碳汇到森林碳汇的形成机制，再到实现监控管理下的可持续森林碳汇。（3）国内森林碳汇研究主线变化从研究测量碳储量的方法，到运用大量方法测量中国森林碳平衡，再到中国森林碳汇稳定区域估计的理论归纳。阶段的热点问题从中国森林碳储量的变化，转变为中国森林是否为碳汇，最后聚焦到中国森林碳汇的形成机制。如今国内研究趋势逐渐与国际接轨，中国在国际森林碳汇研究领域中的学术地位日益提升。在未来，中国需要增加对森林生态系统调查和监测强度，构建"天-空-地"一体化的碳汇计算体系，进而实现对碳汇规模的准确监控。并且需要准确且全面评估森林碳汇对我国实现"碳中和"目标的贡献，推动我国"碳中和"目标的实现。

Abstract:

Forests have a significant impact on the global carbon cycle. Forest-carbon-sinks are a key component of terrestrial carbon sinks, as evidenced by a growing literature in the international community. This study identified 4,973 relevant peer reviewed studies from 1990-2021 using Web of Science and the bibliometric tool “CiteSpace”. These studies formed the foundation of a knowledge map of literature co-citation and keyword co-occurrence networks, which were used to and analyze trends of forest carbon sink research. This study found that: (1) the number of articles on forest carbon sink research continues to grow, suggesting that forest carbon sinks remain a high-priority research topic both in China and abroad; (2) the main topics of research include methodological developments in the measurement of forest carbon balance, generalizing the underlying theory of the estimation of stable forest carbon sink areas, application of theory to practice, and understanding the scale of global carbon sinks’ influence; and (3) the main focus of domestic research includes methods for estimating carbon stocks and balance of China"s forests, and the theoretical integration of China"s stable forest carbon sinks. Therefore, research priorities have shifted from the measurement of China"s forest carbon stock to the identification of carbon sinks, before finally focusing on the generating mechanisms of China"s forest carbon sinks. Currently, domestic research trends are gradually converging with international priorities and China"s academic contributions have gained international recognition. In the future, China needs to increase support for systematic investigations and monitoring of forest ecology and build an integrated "sky-air-ground" carbon sink calculation system for more accurate monitoring of the scale of carbon sinks. Moreover, it is necessary to provide an accurate and comprehensive assessment of the contribution of forest carbon sinks to China’s goals, so as to achieve carbon neutrality.
