本研究基于南京市高淳县语言生活状况的调查。研究发现普通话作为中小城市通用语的主体交际地位正在形成中;高淳话的使用范围有所减少,但依然在家庭等非公共场所保持着较强的语言活力。普通话和方言在中小城市将长期保持竞争和共存状态。 This study is based on a survey of language life in Gaochun County, Nanjing. It is found that the communicative status of Putonghua as the dominant communicative language of small and medium-sized cities is taking shape. The use of Gaochun dialect has been reduced, but still maintained a strong language vitality in non-public places such as families. Putonghua and dialects will maintain long-term competition and coexistence in small and medium-sized cities.
