【Purpose/significance】Try to intergrate cross cultural communication of language information into the view of information ecology, so as to study the process of it from the perspective of information ecology, and to strive for a new explanation and analysis of cross cultural communicaiton of language information.【Method/process】Try to explore the feasibilityof integrating cross cultural language information communicaiton and information ecology form four aspects such as relevance,intelligence,dynamic balance and isomorphism.【Result/conclusion】On the basis of demonstrating the feasibility oftheoretical connection between them, and referring to the three optimization principles of information niche, this papermakes an empirical analysis of information ecology guiding cross-cultural language information communication, which provides a new way of the cross-cultural language information communication research.
