综述了国外社会学理论对少数民族濒危语言的批判性探讨,指出少数民族群体要融入主流社会,就必须放弃自己的民族语言,而从个人的角度讲,融入主流社会才有发展的可能。但从长远来看,放弃少数民族语言是一种集体的损失。这种两难的处境,是语言学家、社会学家或任何人都没法解决的,同时也为社会语言学研究濒于消亡的语言提供了合理的理论框架。 This article summarizes the critical discussion of the theory of sociology of the endangered languages ​​of ethnic minorities in the endangered areas and points out that ethnic minority groups must give up their own national languages ​​if they want to integrate into the mainstream society. From an individual point of view, it is possible for them to develop into mainstream society. However, in the long run, giving up minority languages ​​is a collective loss. This dilemma can not be solved by linguists, sociologists or anyone else, and at the same time provides a reasonable theoretical framework for the study of linguistic linguistics on the verge of extinction.
