摘要：[目的/意义]信息生态位宽度是描述信息人生态位间关系和特征的一项重要指标,信息生态位宽度测度则是对这些关系和特征的量化表达,它可以帮助信息人更清晰地认识自身所处的位置,为其调整信息生态位提供依据.[方法/过程]在阐述信息生态位宽度内涵的基础上,分析信息生态位的多重维度,着重从信息功能、信息资源、信息时空三个维度进行细化分解.借鉴生态学中的相关理论,构建了单维、多维信息生态位宽度测度模型.并选择郑州、武汉两地的6所公共图书馆作为观测对象进行实证研究.[结果/结论]实证结果显示,湖北省图书馆信息生态位宽度值最大,其次是郑州图书馆和武汉图书馆,河南省图书馆的宽度略小,两所少年儿童图书馆的生态位宽度最窄,与实际情况相吻合.
[Purpose/significance]Information niche breadth is one of the most important indicators to describe the relationships and characteristics of information person.The measurement of information niche breadth is a quantitative expression of these relationships and characteristics,which can help information person understand the position more clearly and provide a basis for adjustment of information niche.[Method/process]On the basis of explaining the connotation of information niche breadth,this paper analyses the multiple dimensions of information niche and carries on the detailed decomposition mainly from three dimensions:information function,information resource and information space.Based on the relevant theories in ecology,single-dimensional and multi-dimensional information niche breadth measurement models were constructed.Afterwards,six public libraries in Zhengzhou and Wuhan were selected as observation objects for empirical study.[Result/conclusion]The empirical results show that the information niche breadth of Hubei Province Library is the largest,followed by that of Zhengzhou Library and Wuhan Library.Henan Provincial Library has a slightly smaller breadth,and the breadths of the two children's libraries are the narrowest.This is consistent with the actual situation.
