Abstract: Information’s concept is the most difficult question to answer.So far,the answer to the traditional methods of definition is contrary, which can’t give an explicit definition to the information . Until now,there are dozens of definitions for the information,but each of which only discoveries the essence of the information from one or another side. This paper creates the method of definition based on model approach, and constructes the background that information produces.On this base,the essence of information’s information is described.At the same time,the concept of the
information is given availably.

Key words: information, concept, definition, modeled

摘要： 信息的概念是最基本的也是最难回答的问题，迄今为止，对信息的定义大多是从反面作出的，都没有为信息下一个确切的定义。目前对信息的定义有数十种，但每一种都只从某一侧面揭示了信息的本质，本文基于模型方式的定义模式，构造了信息产生的背景，以此为基础阐述了信息概念的实质，有效地给出了信息概念的定义。
