信息生态链：概念、本质和类型

Information Ecochain:Concept,Essence and Types

借鉴生态学中的生态链理论,探讨信息生态链的概念、本质和类型。认为信息生态链是信息生态系统中不同种类信息人之间信息流转的链式依存关系,并从构成主体、功能实质、依存关系三个方面探讨信息生态链的本质,按信息人的组织形式、信息人信息角色的专兼职程度、信息人种类及其职能多少、所流转的信息内容性质四个标准对信息生态链进行分类。

Using the theory of ecochain in Ecology for reference,this paper discusses the concept,essence and types of information ecochain. The information ecochain refers to the chain-typed relation,which is formed when the information circulates and transits among different information groups in an information ecosystem.The essence of information ecochain is discussed from three different aspects：subject,function and dependent relation.The information ecochain is classified according to four kinds of standard：the organizing form,the extent of full time or part time,the species and function of information people,the characters of information content.
