Theoretical framework for ecological discourse analysis: A summary of New Developments of Ecological Discourse Analysis

Abstract This article is a summary of the newly published book New Developments of Ecological Discourse Analysis. On the premise of reviewing the overall development of ecolinguistics, this book firstly develops the Hallidayan approach and defines Ecological Discourse Analysis as an independent paradigm. Based on the guiding principle of the ecosophy, “Diversity and Harmony, Interaction and Co-existence”, it then expands and extends the experiential, interpersonal, textual, and logical metafunctions within the framework of Systemic Functional Linguistics. Consequently, it constructs the theoretical systems of Ecological Discourse Analysis from the perspective of ecolinguistics: the transitivity system, mood system, appraisal system, Theme system, cohesion and coherence system, and logical system. This book presents readers with a comprehensive and applicable theoretical framework for Ecological Discourse Analysis, that is, “ecological grammar”.
