摘要

非线性动力系统理论(NDS)及其基本概念迅速地向地貌领域渗透和发展,使得愈来愈多的地貌学家运用NDS的知识结构和思维方式认识地貌现象和地貌发展,许多地貌系统在时空上都显示出非线性或混沌的行为和方式。这些复杂性可能是地貌系统的不平衡、组成的多样和外界环境的多变的结果。非线性动力系统理论的基本概念(如平衡、耗散结构、分汊、混沌等)在经典地貌学的领域里都能找到对应物。因此经典地貌学的思想和概念可以在NDS理论框架下得以阐述和解释。

Abstract

The theory and concepts of nonlinear dynamical systems have rapidly extended into the geomorphological field so that more and more geomorphologists have investigated landforms by the knowledge structure and thinking mode of nonlinear dynamic systems theory.Nowadays, it is realized that many geomorphic systems exhibit nonlinear or chaos behaviours and patterns in both spatial and temperal domains. This complexity can arise from none quilibrium of landscapes, diversification of components of the system, and change ability of external environment. In fact, basic concepts of nonlinear dynamical systems theory, for example, equilibrium, dissipative structure, bifurcation and chaos, can correspond to some fundamental ideas of traditional geomorphology, principles and ideas of classic geomorphology, therefore, can be illustrated in the context of nonlinear dynamical systems theory framework.
