基于语料库的生态话语分析——以TED演讲为例

The Ecological Discourse Analysis Based on Corpus—A Case Study of TED Talks

摘要: 随着生态环境问题日益凸显，学界对生态问题的关注也越来越多。生态话语分析关注语言在生态系统中的作用，旨在通过话语分析阐释话语如何体现和影响人类的生态观念并构建人类与生态系统之间的关系。本研究借鉴和吸收语料库语言学和话语分析研究成果，建立小型语料库，建构语料库辅助生态话语研究多维分析框架，通过词频，搭配，索引，主题词等语料库分析技术，对2003年至2023年有关气候变化的TED演讲稿进行分析，探究气候变化的成因及解决措施，呼吁人们关注气候变化，保护环境，节约能源。

Abstract: With the increasing prominence of ecological environmental problems, the academic community pays more and more attention to ecological problems. Ecological discourse analysis focuses on the role of language in ecosystem, and aims to explain how discourse reflects and influences human ecological concepts and build the relationship between human and ecosystem through discourse analysis. This study draws on the research results of corpus linguistics and discourse analysis, builds a small corpus, constructs a multidimensional analysis framework of corp-based ecological discourse research, and analyzes TED speeches on climate change from 2003 to 2023 through corpus analysis techniques such as word frequency, collocation, index and subject words, to explore the causes and solutions of climate change, call on people to pay attention to climate change, protect the environment and save energy.
