方言接触中的调值问题——以湘南双方言为例

On the Tone Values in Dailect Contact ——An Example from Bidialects in Southern Hunan

双方言区两种属性不同的方言,声调归并不一定相同,但调值却有相同之处;同一属性的方言在不同地点,声调归并相同,但调值却有差异。在双方言区,不同方言声调的接触首先造成调值的接近,而后造成调类的归并。

The different dialects in bidialect area have different tones but similar tone value. The same dialect in different area has the same tone but different tone values. In bidailect area, contact of dialect tone firstly causes similarity of tone value and then combination of tone category.
