| 摘 要： | 在地球早期至今的几十亿年历史长河中，行星地球从过去的早期阶段到现今阶段是受整个地球系统发展的结果。借鉴地质历史演化，地球系统的过去状态特性对预测将来是非常有助的。温室效应尚不确知，因为这样一个问题难以解释，即近期１５０万年甚至整个第四纪２４０万年内冰期与间冰期相间出现，与人类释放ＣＯ＿２或消耗燃料无关。ＣＯ＿２或ＣＨ＿４叠加大气温度的变化趋势到底是什么？平流层的臭氧是否也有自身修复的功能，它自身是否也在变化？固体地球科学作为地球科学前沿，需要持续发展，应当参与全球变化研究。

| 关 键 词： | 固体地球科学，温室效应，臭氧亏损，可持续发展 |

| Abstract: | The planet Earth is traced in a long history of billions of years from its earlystages to the present conditions of the whole earth system. To understand the nature of itspast behavior in the light of geological history is very helpful for predicting the future.The greenhouse effect is in uncertainty because of the difficulty of how to explain the re-peated alternation of glaciations and interglaciations in the last 1.5 or even 2.4 Ma inQuarternary without man-made emission of carbon or fuel.What is the tendency of the atmosphere temperature the CO_2 or CH_4 superposes. Another example of uncertainty is whether any natural variation of the ozone exists in strato-sphere and its self-recovering effect occurs in this variation. The solid-earth sciencesshould partake the global change as the frontier of the earth sciences in sustainable devel-opment. |
