鄂东南赣语的[v]声母有残存型和新生型两类,残存型来源于微、影、喻三、匣四类声母;新生型来源于溪、群、影、喻三四类声母。在分布图上,前者表现出零碎、杂乱的分布特点;后者有自己固有的分布区域,在地域上呈连续性分布态,具有较强的规律性。本文研究表明,语音地图在考察汉语方言语音历史的过程中可以发挥重要的作用。 There are two types of initials [v] in southeastern Jiangxi. The remnant comes from four types of initials: micro, shadow, metaphor and box. The newborn comes from three types of consonants, such as stream, group, shadow and metaphor. In the distribution map, the former shows fragmented and disorderly distribution characteristics; the latter has its own inherent distribution area, which is distributed continuously in the geographical area and has a strong regularity. This study shows that phonetic maps can play an important role in examining the phonetic history of Chinese dialects.
