| 摘 要： | 文中综合分析可以影响新生代全球变冷的四种原因，提出青藏隆升对新生代大气ＣＯ２浓度降低起主导作用，对新生代全球气温的降低起关键控制作用。这种作用是通过青藏高原隆升加剧全球硅酸盐岩和碳酸盐岩的化学风化、有机碳埋藏、植物的光合作用来实现的。而且，青藏高原隆升有可能同洋流改变和行星轨道参数变化于第三纪末至第四纪共同对新生代全球变冷起控制作用。因此，目前首先解决的科学目标应该是：精确刻划青藏高原隆升时代和幅度，并确定青藏高原隆升对新生代全球变冷的贡献，确定一种以青藏高原隆升为主导作用的控制新生代全球变冷的综合模式。

| Abstract: | The facfors which forcing Cenozoic global cooling includes probably uplifting of the Qinghai Tibet Plateau,changing of ocean current,atmospheric CO 2 concentration,and orbital parameters etc.It would be that the Qinghai Tibet Plateau uplift was control factor which casued reducing the atmospheric CO 2 concentration in the processes of chemical weathering of silicate and carbonate,organic carbon burial,and uplifted plant photosynthesis.The future research should aim at the precise uplift processes of the Qinghai Tibet Plateau in time and scope and its influence on the Cenozoic global cooling,in order to determine a comprehensive model which has controlled the Cenozoic global cooling. |
