从文白异读与语言接触看声调特征的稳定性
Discussing the Stability of Tonal Features through Literary and Colloquial Readings and Language Contact

声调作为汉语重要的语音特征，其声学表现、起源和演变一直是语言学界关注的重点。以发生学的视角看，文白异读、汉语与少数民族语言接触可以一同视为泛语言接触。从文白异读与语言接触来观察声调特征的稳定性，可以发现文白异读揭示汉语方言内部接触倾向于保留弱势方言土语层声调特色，而汉语方言与无声调少数民族语言接触则容易发生调类增减等显著变化。
As an important phonological feature of Chinese, the phonetic manifestation, origins, and evolution of tones have always been a key focus in the field of linguistics. From a diachronic perspective, literary and colloquial readings, as well as the contact between Chinese and minority languages, can both be regarded as forms of broad language contact. Examining the stability of tonal features through these two factors reveals that literary and colloquial readings indicate that internal contact within Chinese dialects tends to preserve the tonal characteristics of weaker dialects. In contrast, contact between Chinese dialects and tonal-less minority languages often leads to significant changes, such as the addition or reduction of tonal categories.
