摘 要:文章探讨了信息生态群落演替的概念、过程和特征。信息生态群落演替是指某一区域范围内一种信息生态群落被另一种信息生态群落所取代的过程,其过程由群落内优势种的改变、信息生态种群对群落内部生态环境的适应和改造、群落内种群关系的调整和群落内部结构的相对稳定4个阶段组成。信息生态群落演替具有以主动演替、外因演替、突变式演替为主和无顶级群落等特征。This paper discusses the concept, process and characteristics of information ecological community succession. Information ecological community succession is the process of one information ecological community replaced by another one in certain area, and its process consists of 4 stages, that is, the change of the dominant spe- cies within the community, the adaptation of information ecological population to the ecological environment within the community and its transformation, the adjustment of the population relationships within the community, and the relative stability of the internal structure of the community. The information ecological community succession has the characteristics of giving priority to active succession, giving priority to external succession, giving priority to mutation-based succession and having no climax community.
