摘要: 生态系统具有异质性、非线性、多层次性等复杂特性.针对生态系统的复杂性,从统计动力学的视角出发,从生态组元相互作用的微观动力学角度,对生态系统分形层次结构的起源及其形成过程的动力学机理进行了初步探讨,并分析了生态系统分形维数的影响因素及机理.对理论结果与实际例子进行了比较,并讨论了在实践中的可能应用.

Abstract: Ecosystem is typically characteristic of heterogeneity, non-linearity, and multi-hierarchy etc. Aimed at the complexity of ecosystem and from the viewpoint of statistical dynamics, this paper approached the dynamic mechanisms of fractal hierarchical structure in complex ecosystem, analyzed the affecting factors of fractal dimension, compared the theoretical analyses with practical examples, and discussed the possible applications in practice.
