森林生态系统碳储量研究进展与展望

Research Progresses and Prospects of Carbon Storage in Forest Ecosystems

回顾了近30a来国内外森林生态系统碳储量的研究现状与进展,通过对已发表文献的年度分布、研究内容、研究区域、研究机构进行分析,将森林生态系统碳储量研究划分为2个阶段,1991-2006年为萌芽阶段,2007年至今为快速发展阶段,依据研究内容从理论研究、技术研发、监测评价、模型构建与格局揭示5个方面进行了归纳总结,提出今后应开展多途径交叉验证以减少碳储量估算误差;研究碳汇林培育的人为影响因子与技术体系;进行长时间序列的连续监测;建立凋落物与根系的完整数据库;开发适合中国实际情况的大气反演模型;探讨森林固碳与生物多样性保护等生态功能之间的关系;揭示植物功能性状对固碳功能的指示作用。

This paper systematically reviewed the research status and progress of carbon storage in forest ecosystems at home and abroad in the recent 30 years.Through the analysis of the annual distribution,research content,research area and research institutions of the published literatures,researches on forest ecosystem carbon storage were divided into two stages:initial stage (1991-2006) and rapid development stage (2007 to now) According to the research content,five aspects were summarized:theoretical research,technology research and development,monitoring and evaluation,model construction and pattern disclosure.It was proposed to carry out multi-channel cross-validation in order to reduce the estimation error of carbon storage,to study the human influence factors and technical systems of carbon sink cultivation,to conduct continuous monitoring of long-term sequences,to establish a complete database of litter and roots,to develop an atmospheric inversion model suitable for Chinese actual situation,to explore the relationship between forest carbon sequestration and ecological functions such as biodiversity conservation,and to reveal the indicative effect of plant functional traits on carbon sequestration.
