及物性系统下虎鲸身份建构的生态话语分析

Ecological Discourse Analysis of Identity Construction of Killer Whale from the Perspective of Transitivity System

基于系统功能语法及物性理论,借助语料库工具对虎鲸生态评估报告中的语言特征以及虎鲸的身份建构路径进行了研究,旨在揭示生态评估报告中的生态取向。研究表明,涉及虎鲸的参与者角色大都由物种集体名词以及商业化、公式化、科学研究性名词实现,将虎鲸建构为为人类服务的意义表征和工具性身份特征;三大及物性过程多使用被动结构将虎鲸识解为“被动接受者”“无主动行为者”和“无意识者”的身份。生态报告中建构虎鲸身份使用的语言资源不符合深层生态思想。

The paper studies linguistic characteristics of ecological assessment reports and the path of identity construction of killer whale from the perspective of transitivity system in virtue of corpus tools so as to reveal the ecological orientation of ecological assessment reports.It demonstrates that roles of killer whale are mostly represented by collective nouns of species and commercialized,formulaic as well as scientific research nouns which turn killer whale into semantic representation and instrumental identities for human purposes.Killer whale is often interpreted as "passive recipient","unconscious and inactive actor" and "server" by the three processes realized by passive structures.Language resources used as identity construction of killer whale in the text do not conform to the deep ecological thought.
