Investigation And Study Of The Phonetic Differences Between The New And Old Schools Of The Lu’an Dialect

The construction of Lu’an began in Xia,and Shunfeng Gao Tao was in Liu;The name Lu’an began in the Western Han Dynasty,and Emperor Wudi of Han took the meaning of "peace in the six lands and never rebellion".Geographically,Lu’an is located in the southwest of Anhui Province,also known as western Anhui,located between the Yangtze River and the Huaihe River,bordering Henan and Hubei in the northwest and southwest directions,mostly hilly areas,belonging to border cities,with economic development and policy support,transportation extends in all directions;From the perspective of language research,Hongchao Piece,which belongs to the Jianghuai official dialect area,because it is an atypical area of Jianghuai official dialect,has few research works and literature,and lacks systematic description.Based on the actual fieldwork,this paper selects the main streets,communities and schools in Lu’an City as dialect investigation points,takes the difference between the new and old school pronunciations of the Lu’an dialect as the core,attempts to make a dynamic description of the pronunciation of the Lu’an dialect,and is committed to analyzing the reasons for the evolution of the Lu’an dialect from the perspective of sociolinguistics.The full paper consists of five chapters,which gradually explore the phonetic differences between the old and new schools of the Lu’an dialect,and conclude as follows:Firstly,by using the fieldwork method,through the collation and analysis of the pronunciation of two old-school dialect pronunciation collaborators and two new-school pronunciation collaborators,the new and old-school phonological systems were systematically described,and a list of the new and old school phonological tonal relationships was produced.Then,by analyzing the phonology of the new and old schools of the Lu’an dialect,the commonalities and differences of the old and new sounds were found,and it was found that the differences between the new and old school vowels and vowels were the most obvious,and the difference in tone was the least obvious.Secondly,the representative phonetic differences between the old and new schools of the Lu’an dialect were selected and the "Questionnaire on the Phonological Differences between the Old and New Schools of Lu’an Dialect" was produced.Then,using the quantitative research method of sociolinguistics,questionnaires were distributed in the main streets,communities and middle schools of Lu’an City,effective questionnaires were obtained and the content of the questionnaire was statistically analyzed,so as to explore the relationship between the phonetic differences and social factors of the new and old Lu’an dialects,analyze the reasons for the differences,and believe that the strong dialect-Mandarin had the most profound impact.Finally,according to the discussion in the above chapters,the characteristics of the new and old phonetic differences of the Lu’an dialect are summarized,and the laws and development trends of the phonetic evolution of the Lu’an dialect are described.
