摘要
复杂科学的理论、方法在生态系统的研究应用具有很高的价值。生态系统是一个复杂适应性系统,处于混沌边缘或临界态,内部作用是生态系统复杂化、有序化及自组织的主要推动力。生态系统复杂性是目前生态研究的前沿领域之一。文章介绍了生态系统的复杂性和利用复杂科学的原理和方法来研究进化和生态学问题。生态系统复杂性就是生态系统内不同层次上的结构与功能的多样性,自组织性及有序性。其研究方法主要有元胞自动机法、遗传算法、博弈论、复杂网络等。运用复杂科学的原理和方法,探讨生态系统复杂性的机理及发展规律,为认识和解决生态问题提供一条新的途径。
It is valuable to be researched in the application of complexity science on ecosystem. Ecosystem is a complex adaptive system which is suggested to be at the edge of chaos or at the criticality. The inner interaction of an ecosystem is the main driving force for the self-organization, complexity and order in the ecosystem. Ecosystem complexity is one of the research frontiers of ecological problems presently. The application of science of complexity to the ecosystem complexity studies, its concept, background, methodology and theory are briefly introduced. The ecosystem complexity is defined as the structure and function diversity, self-organization and the order of an ecosystem. Its main methods include the cellular automaton, genetic algorithm, game theory, complex network, etc. This paper has discussed mechanism and development of ecosystem complexity, by applying the principle and methods of science of complexity, which is a new approach for understanding and resolving ecological problems.
