摘要: 生态系统可被视为具有等级结构的复杂系统。由于当前对复杂生态系统建模与仿真的共性问题总结较少,导致现有建模与仿真活动的规范化和集成化程度不高,限制了现代生态学的发展。针对当前存在的问题,本文在提出复杂生态系统建模与仿真总体框架的基础上,以系统与系统模型作为建模与仿真的两个主体,分别从自上而下的系统分析与自下而上的模型实现(即系统综合)两个方面对复杂生态系统建模与仿真的策略进行了探讨,重点剖析了复杂生态系统建模与仿真的共性基础与技术。希望能为今后复杂生态系统建模与仿真的具体案例研究提供一些有益的启示。

Abstract: An ecosystem could be regarded as a complex system with hierarchical architecture. Due to the lack of standardization and integration, the current modeling and simulation of complex ecosystems could not fit in with the further development of modern ecology. A primary reason for this is that very few reviews on modeling and simulation of complex ecosystems have been presented. In this regard, this paper proposes a general framework for modeling and simulation of complex ecosystems. Based on the framework, systems and system models are taken as two kinds of main agents, and the strategies for modeling and simulation of complex ecosystems are discussed in terms of two approaches-top-down system analysis and bottom-up model realization (i.e. system integration). It is intended to provide a useful guidance for further case studies on modeling and simulation of complex ecosystems.
