With the rapid advancement in digital humanities in recent years, the combination of environmental and ecological discourse analysis with corpus-based approaches has emerged. Based on the definition of related concepts, the research objects and methodologies, this paper reviews the status quo of corpus-based environmental and ecological discourse analysis, and discusses existing problems in data collection, corpus building, research topics, perspectives and methodologies. It suggests that future studies should enhance the application and construction of corpora in relevant research, broaden research perspectives and methodologies, and prompt the development of research in this field.
