摘要
首先从人类面临全球性的重大问题、地球系统的全球化和地球系统科学的关系与传统地球科学三个方面介绍了地球系统科学提出的背景,阐述了地球系统科学国内外研究现状.然后,详细介绍了地球系统科学的概念与研究方法,主要包括研究思路、基本概念、地球系统过程、全球———区域信息获取、海量信息处理和分析及地球系统模型等.第三,构建了地球系统科学理论基础.主要包括:地球系统的连续动态系统、离散动态系统、地球系统的随机性、地球系统的自组织和地球系统的简单巨系统与复杂巨系统,重点介绍了地球系统科学子系统与各圈层相互作用的动力学模型与效应.第四,概述了地球系统的数字表达—数字地球和地球系统科学是可持续发展战略科学基础.最后,简述了中国开展地球系统科学研究的方向和面临的主要科学问题.
Background of earth system science put forward was introduced firstly from three aspects which were global important problems for human being facing on, globalization of earth system and earth system science and traditional earth science. The study state at home and abroad of earth system science was expounded on above basis. Concept and study methods of earth system science were introduced in detail then. The contents are study thought, basic concept, process of earth system, globe-region information obtaining, magnanimity information processing and analysis and system models and so on. Thirdly, theoretical base of earth system science was constructed. The main contents included continual dynamical system of earth system, discrete dynamical system, randomicity of earth system, self-organization of earth system, simple giant system and complex giant system of earth system. Dynamics models and the offect of interaction between subsystem of earth system science and each circle were emphasized to be introduced. Fourthly, that digital express of earth system-digital earth and earth system science are base of sustainable development stratagem science was summarized. Finally, the study direction of earth system science developed in China and its main scientific problems facing on described briefly.
