The contradiction between the global concern and local reality of environmental issues has led to the binary path of global or local analysis. The binary path of global or local analysis is no longer applicable. Trans-localism, with its characteristics of linkage, integration and reconstruction, is expected to bridge the theoretical gap between global and local. Based on this, this paper focuses on the study of trans-localism in environmental communication, and discusses the theoretical origins, value connections, and influence of this concept. The study finds that trans-localism demonstrates a spatial understanding and plays an important role in environmental communication in three aspects: relational connection, public interconnection, and political embeddedness. The study finds that trans-localism plays an important role in environmental communication in three areas: relational connection, public interconnection, and political embeddedness. It also presents a change in the understanding of spatiality, presenting the value dimensions of spatial practices, spatial representations, and representational spaces.
