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。
Introduces the characteristics of r and K countermeasure theory in ecology and introduces the r-K countermeasure theory in ecology into information ecology. Based on the information bandwidth and synchronization, the r-K attributes of different information types in the information ecosystem are compared and classified. It is pointed out that the types of information with high bandwidth and low synchronization in information ecosystem tend to K countermeasure. The information types with low bandwidth and high synchronization tend to r countermeasures. The countermeasure is to improve the quality of information and increase the cost of each piece of information. The countermeasure of low bandwidth and high synchronization is to increase the amount of information and reduce the cost of each piece of information. Based on the analysis of r-K countermeasure characteristics in network information, this paper proposes the development trend of r-K countermeasure in information field.
