对人工智能科普话语的生态性探究

在环境问题日益凸显的大背景下，生态话语分析为语言研究者分析话语生态性提供了新的思路。其研究对象包括环境类语篇和非环境类语篇，旨在引导人们言行生态化。作为非环境类文本，人工智能科普语篇以新颖有趣的话语方式，既向人们传播了AI 技术新发展，也反映了写作者的语言生态观。为揭示此类语篇生态取向，文章结合系统功能语言学和生态语言学理论，以20 篇英文AI 科普文章为语料，从及物性视角对语篇进行表层描述和深层生态解读。研究表明:表层来看，AI 科普语篇语义配置方式倾向使用以社会性场所为施事的物质过程和关系过程，借此实现向读者科普AI 知识的语义功能。深层来看，该类语篇生态取向主要表现为生态模糊型和生态保护型，这很大程度上是由科学界对AI 所秉持的科技生态观决定的。 

Ecological Analysis of Popular Science Articles on Artificial Intelligence

Under the background of increasingly prominent environmental problems,ecological discourse analysis provides a new way for language researchers to analyze the ecology of discourse. Its research objects include both environmental and nonenvironmental texts to guide people to think and act ecologically. Popular science articles on artificial intelligence,as non-environmental ones,communicate new advancements of AI to people in innovative and interesting discourses;meanwhile,they also reflect editorialists' linguistic ecological view. To reveal the ecological orientation of this kind of discourse,the author,combining the theory of SFL with Eco-linguistics,analyzes both superficially and deeply 20 English popular science articles on AI from the perspective of transitivity system. The research shows that,from the surface layer,this kind of text mainly takes the social place as the participant agent,and uses lots of material process clauses and relatively numerous relational process clauses to realize the semantic function of popularizing AI knowledge to readers. From the deep light,the writer's ecological orientation is mainly characterized by ecological ambiguity and ecological protection,which results from the ecological view of science and technology held by science community.
