浅议地球系统的复杂性及非线性

Intial Study on the Complexity and Non - linearity of the Earth System

结合复杂性科学的产生及发展历程,认为复杂性科学对研究地球系统复杂性及非线性具有重要的理论指导和方法论意义。同时,在论述地球系统基本属性的基础上总结了地球系统复杂性及非线性的具体表现,即地球系统的层次性、无特征尺度性、开放性、相干性、临界性、自组织性和其动力学行为的自相似性及分形性。认为地球系统是总体上远离平衡、时空延展的多层圈综合集成、连续开放的复杂耗散动力巨系统。随着复杂性科学和地球系统的复杂性及非线性研究的不断深入,在２１世纪,地球科学研究将会取得理论上的重大突破和飞跃。

Combined with the produce and development history of science about complexity, the new science is thought to have important significance of theory and methodology for researching the complexity and non-linearity of the earth system. Meanwhile,on the base of the basic nature of the earth system, the concrete characteristics of the complexity and non- linearity of the earth system is stated,concluding hierarchy, non-feature scale, openability, coherence, criticality, self-organizedation of the earth system and self-similarity and fractality of its dynamic behavior. It is pointed that the earth system is far from equilibrium overall,temporal-spatio ductility, multi-spheres generally integrated and complex mega system, which is also continue, open and dissipative. Companying the successive deepgoing research work about the science of complexity and the complexity and the non-linearity of the earth system, the earth science will make important breakthrough and leap in theory in the 21st century.
