Abstract: Under the increasingly drastic external environment, the requirements to develop information literacy education could not be resolved by library alone. Therefore, to enhance students’ core information literacy, it is necessary to construct an information literacy education ecosystem involving multiple parties, such as subject faculty, librarians, faculty center’s staff and other personnel. Based on the analysis of the environment supported with policy, information technology, content and training objective, the connotation and structure model of information literacy education ecosystem are put forward by means of the ecology theory. Under specific conditions, whether the dynamic equilibrium could be formed among its communities, and whether the communication channels could be kept open smoothly and stably for material cycle, energy flow and information exchange are the foundation and precondition for the ecosystem to run well and realize its functions.
