海南崖城军话韵母系统的链式音变

Chain Shift in the Rhyme System of Yacheng Junhua in Hainan

崖城军话来自官话,传入海南后在接触、发展中产生了官话没有的两个音系特征:长短元音与e介音。其中有高化、低化两个方向的四组音变链。音变的诱发动因来自方言接触的外部借入,音变的结果源于崖城军话内部在周边黎语、闽粤方言特定语言环境下的整合。

Yacheng Junhua,a descendent of Mandarin spoken in Hainan Island,develops two phological features absent in Mandarin,the length distinction of vowels and the vowel medial-e-,which result from language contact and evolution of this Mandarin variety in Hainan.These two features involve four chain shift respectively in the direction of heightening and lowering.These sound changes are triggered by sound borrowing arising from language contact,while the phonological features result from the internal integration of Yacheng Junhua in the language environment of the surrounding Li language and the Min and Cantonese Chinese dialects.
