【摘要】 生态语言学主要探讨如何使用语言表征、推崇和鼓励有利于生态环境的社会实践，语言所构建的话语和“故事”如何影响人类的行为和整个生态系统。然而，语言为何会漠视生态环境?生态语言学并没有给出答案。以这一问题为切入点，本文对比了动物符号系统和语言符号系统的差异，指出前者是指示符号，必须完全依赖生态环境才能进行交流，而后者是抽象符号，具有一定的相对封闭性，无需完全依赖生态环境也可以进行交流。本文讨论语言符号系统表现出的相对封闭性，然后从语言符号系统的特点出发，论证了这种相对封闭性是造成语言漠视生态环境的主要原因之一。更多还原

【Abstract】 Ecolinguistics mainly explores how language uses represent, reward and encourage social practices which benefit ecological environment as well as how the discourses and “stories” constructed by language affect human behaviors and the whole ecological system. However, why does language ignore or disregard the ecological environment? Ecolinguistics gives no answer to this question. Based upon the starting point of this question, the paper makes a contrastive analysis between animal semiotic system and linguistic semiotic system and points out their differences, with the former being indexes, completely relying on ecological environment in order to communicate while the latter being symbols characterized by its relative closure property, without relying on ecological environment. The paper discusses the relative closure property exhibited by language and argues that this property is one of the major causes for language to ignore or disregard the ecological environment.更多还原
