冰期旋回中的碳循环是一个复杂的地球系统科学问题。尽管取得了很大进展,但是定量精细的循环过程仍未解决。其中一个重要的限制因素就是对于陆地生物圈碳储库及其变化的估算尚存在很大的不确定性。位于热带东南亚的巽他群岛是当今陆地生物量最丰富的三大热带森林区之一,对全球陆地生物圈碳储库有重要贡献。在冰期海平面下降时临近的巽他陆架出露成陆地,使得该区域陆地面积增大1倍。出露陆架上的植被状况有可能对冰期旋回中的碳循环产生重要影响。对冰期旋回时的碳循环进行了介绍和讨论,认为应加强对冰期巽他陆架地区古气候和古生态的研究,为定量分析和模拟冰期旋回中的碳循环提供关键数据。

The glacial-interglacial carbon cycle is a complex scientific issue of the earth system. Although many progresses have been made, it is still far from being solved. Among others, an important limiting factor is the great uncertainty in the carbon stock in the terrestrial carbon reservoir. The present Sunda Islands are one of the three tropical forest areas with most abundant terrestrial carbon biomass and contribute greatly to the global terrestrial carbon reservoir. During the glacial low stands, the adjacent Sunda Shelf was exposed and led to a doubled land area. The scenario of terrestrial vegetation, which is not well understood, on the exposed land is probably a key factor to the global carbon cycle. Thus, a comprehensive paleoclimate and paleoecology study for the area is appealed, which may provide key data to quantitative analysis and modelling of the global glacial-interglacial carbon cycles.
