摘要

介绍生态学中的r及K对策理论特点,将生态学中的r-K对策理论引入信息生态学。以信息的带宽和同步性为标准对信息生态系统内不同信息类型的r-K属性进行量化比较并进行分类。指出信息生态系统中高带宽、低同步的信息类型倾向于K对策,低带宽、高同步的信息类型倾向于r对策。高带宽、低同步的K信息类型其对策是提高信息质量,增加每条信息的成本;低带宽、高同步的r信息类型其对策是提高信息数量,降低每条信息的成本。在分析网络信息中r-K对策特点的基础上提出信息领域r-K对策的发展趋势。

关键词： 信息生态; r对策; K对策

Abstract

The r-K theory is analyzed and introduced into information ecology. Based on information of bandwidth and synchronicity, different kinds of r-K characteristics are both quantified and classified. While the information with high bandwidth and low sync in information ecology prefers to K-strategy, those with low bandwidth and high sync to r-strategy. K-strategy information is distinguished with high information quality through increasing the cost in each piece of information, whereas the r-strategy information is distinguished with low information quality through decreasing the cost in each piece of information. Finally, this paper proposes the developing trend of the r-K strategy on the basis of its features.

Key words： information ecology; r-strategy; K-strategy
