本文着重指出:通过对大气、海洋、冰盖、生物圈、地壳和地球内部各自独立的研究,地球科学已取得传统的进展,近代研究正在阐明连接这些组成部分的动力相互作用,并将它们看作为整个地球系统的不可分割的各部分。现在,全球观测、新的空间技术和定量模式给了我们探测复杂的地球演变的相互作用过程和全球变化的能力。作为全球变化计划,本文论述了地球系统科学的形成背景、目的、内容和建议性计划。最后概要介绍了美国国家科学基金会正在执行的全球地学计划,十分显明,这个全球地学计划是全球变化计划(又称作国际地圈生物圈计划)的一部分。
This article highlights: Earth science has made its traditional advances through independent studies of the atmosphere, oceans, ice sheets, the biosphere, the crust, and the Earth's interior. Modern research is shedding light on the dynamic interactions that connect these components as An integral part of the Earth system as a whole. Now global observation, new space technologies and quantitative models give us the ability to detect complex interactions and global changes in the evolution of the Earth. As a global change plan, this article discusses the formation of the Earth System Science background, purpose, content and recommendations of the plan. Finally, an overview of the global geosciences program being implemented by the National Science Foundation shows that it is very clear that this global geoscience program is part of the Global Change Program, also known as the International Geosphere Program.
