| 摘 要： | 冰期-间冰期的陆地碳库变化成为最近十几年来碳循环研究的热点之一,以深海氧同位素、模型模拟和古环境证据等手段展开对不同时间尺度上不同碳库之间碳通量变化研究.土壤碳库的巨大储量导致了土壤碳库的任何微小波动都比陆地生态系统其他碳库更容易影响陆地生态系统碳循环以及大气CO2浓度,并最终影响到全球气候变化.通过对过去4万年来黄土...

| Abstract: | Glacial-interglacial change in terrestrial carbon pools is an unknown issue in paleo-carbon cycle research.Carbon flux between carbon pools in different time scales has been studied from marine isotope,model simulating and paleo-environmental evidence by many scientists.Any tiny fluctuation of soil carbon pool with vast carbon reserves would affect ecosystem more easily than other terrestrial carbon pools and atmospheric CO2 concentration,and in turn impacted global climate finally.In this paper,the evoluti... |
