| 摘 要： | 准确估算陆地生态系统碳储量并认识其空间分布和时间演变规律是碳循环研究的关键 问题。本文回顾了全球与中国陆地生态系统在碳储量估算研究方面的若干进展, 包括基于各种方 法和资料的主要估算结果及其尚存在的不确定性。重点评述了末次盛冰期和中全新世两个时期 陆地生态系统碳储量的变化及其影响因素, 对8.2kaB.P.以来全球大气CO2 浓度呈现升高的现象 及其可能原因进行了讨论。全新世中晚期全球大气CO2 浓度逐渐升高与旧大陆地区陆地生态系 统碳储量减少的事实是一致的, 新石器时期特别是农业文明开始以后人类活动对陆地植被的持 续干预可能是造成陆地生态系统碳储量减少的原因之一。

| Abstract: | Estimating carbon storage of terrestrial ecosystem and understanding its spatial distribution and temporal evolution are the key to the carbon cycle study. This article summarizes some major results of the estimations of terrestrial ecosystem carbon storage in globe and China, including the existing problems and uncertainties in the studies. Progress in studies of the carbon storage change since the Last Glacial Maximum ( including the Mid- Holocene) and the influencing factors, especially the potential relationships between the changes and the anomalous increase of the atmospheric carbon dioxide since 8.2 ka B.P. is evaluated. A main conclusion that could be drawn from the overview is that the increase in atmospheric carbon gases (CO2、 CH4) concentrations seems coincident with the decline of the terrestrial carbon storage during the mid to late Holocene, and these might have been caused by the impact of anthropogenic activities on terrestrial vegetation during the agricultural era in the old continents. |
