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.
