语言是人类最重要的交际工具,语言更是社会交际的工具。没有社会,语言就无从存在。在四川凉山这样一个多民族混居的社会,人们使用的语言网错综复杂。本文根据四川省凉山彝族自治州的实际语言运用情况,主要对该地区汉、彝族人民的语言使用进行梳理,运用语言接触知识,探讨了该地区语言的竞争在语言表达功能和语言使用功能上的种种表现,希望能通过语言规划来促进改地区和谐的语言生活。 Language is the most important communication tool of human beings, and language is a tool of social communication. Without society, language can not exist. In a multi-ethnic society like Liangshan in Sichuan, the language networks used by people are complex. Based on the actual use of language in Liangshan Yi Autonomous Prefecture in Sichuan Province, this paper mainly reviews the language usage of Han and Yi people in this area. By using the knowledge of language contact, this paper discusses the features of language competition and language use in this region. It is hoped that language planning can be used to promote harmonious regional language life.
