Sociolinguistical Investigation On Phonetics Of Baduhua Of Guapoqiao Village In Jianghua County

This thesis fouses on the Baduhua of Guapoqiao Village of Jianghua county in Hunan. On the basis of plentiful materials which come from the auther's first-hand field work, this thesis, from the sociolinguistical point of view, investigates the phonetic variation of Baduhua, analyzes the causes of phonetic changes and development of Baduhua and gives a prediction to the developmental trend of Baduhua.Five chapters can be divided in this thesis.The first chapter: preface.The second chapter: the old phonological system of Baduhua and the phonological syetem of Mandarin in Guapoqiao village.The third chapter: sociolinguistical investigation of the phonetics of Baduhua.The fourth chapter : the causes and trend of changes and development of Baduhua.The fifth chapter: concluding remarks.Through investigation and analysis, this thesis holds that in the long period of contact and influence, Jianghua Mandarin has exerted certain effects on the phonetics of Baduhua. Age is the most important factor which causes phonetic variation of Baduhua and the extent of influence increases successively when age decreases gradually. Getting close to Jianghua Mandarin which is the local prestigious dialect is the direction of changes and development of Baduhua.This thesis also predicts that though the trend for Baduhua' getting close to Jianghua Mandarin and even to Putonghua is a irrisistable, villagers in Guapoqiao will be confronted with a long bidialect period (Baduhua and Jianghua Mandarin) before they come to use Jianghua Mandarin only because of the relatively slow speed of development of Baduhua.
