Study on the Complicated Dynamical Behaviors of Nonlinear Ecosystems(Ⅲ)

摘要: 本文继续文献[1～2]的研究,首先引进了生态系统的系综概念,在此基础上比较详细地讨论了生态协同学的微观方法和宏观方法.将这二者结合起来,利用生态系统输出(或可以测得)的宏观数据,建立广义金兹堡-朗道方程(GGLE),把握广义相变(群落演替)前后的信息变化,找出其微观对客观结果的作用机制,这也许是对复杂生态系统作用机制研究的一条新途径.Abstract: This paper is a continuous study of references [1-2]. At first, we introduce the concept of assembles of ecosystems, and then discuss macro- and micro-synergetical methods for ecology study. Combining the two methods, by use of the macroscopic data(observable) outputted from the ecosystems, we can construct their GGLE, master their information changes between, before and after the generalized phase changes(e.g. community successions), and find out the action mechanisms of microscopic factors on macroscopic results. This may be a new approach to the study of action mechanisms of complex ecosystems.
