摘要: 森林是重要的碳汇,每年吸收化石燃料燃烧释放二氧化碳量的33%。自1850年来全球气温已经增加了1.1 ℃,未来全球气温可能会增加到2.7~4.8 ℃。但全球变暖对森林碳汇功能影响方向、程度及其机制存在激烈的争议,严重影响对全球未来气候变化的预测和政府碳排放控制政策的制定。本文综述了全球变暖对森林生态系统碳汇功能影响的机制、研究方法和主要结论。在此基础上,分析现有研究的不确定性,并提出未来的研究方向。

Abstract: Forests are important carbon sinks, absorbing about 33% of the carbon dioxide released from fossil fuel combustion each year. Since 1850, global temperature has increased by 1.1 ℃, and in the future, global temperatures are likely to rise to 2.7-4.8 ℃. However, there are controversies over the direction, degree, and mechanisms of the impact of global warming on forest carbon sequestration, which seriously affects the prediction of future global climate change and the policy-making of government carbon emission control. This article summarizes the mechanisms, research methods, and main progresses of the impact of global warming on the carbon sink capacity and processes of forest ecosystems. In addition, we propose future priority research areas.
