The Phonology Of Guxian(Yaodian) Dialect And The Comparative Study Of The Dialectal Phonology Of Guxian(Yaodian) With Its Peripheral Dialects

Guxian belongs to Linfen City,Shanxi Province.Yaodian is located in the southwest of Guxian.Guxian(Yaodian)dialect belongs to Pingyang small piece,Fenhe part of Zhong Yuan Mandarin.Based on fieldwork,this thesis describes the phonetic system of Guxian(Yaodian)dialect by synchronic description and historical description,including the rhythm system,the homonym vocabulary,the phonological change,textual reading,the literary contrast,and the comparison with middle ancient sound.The Guxian(Yaodian)dialect has a total of 25 initial consonants,42 finals and 4 monogram tones.The textual reading in dialects is very rich,and there are 16 different reading laws.In addition,the phonological changes are more complex,and there is a great difference between the two character groups of non-overlapping characters and the two-character groups of overlapping characters.On the basis of systematic phonological description,this thesis compares the tone of Yaodian dialect with its surrounding six dialects,summarizes the tone gradient chain of Pingyang small piece of Fenhe part.Predicting the tone development trends.Exploring the influencing factors that contribute to this trend.We look forword to understanding the voice appearance and the internal dynamic development trend of Pingyang small piece of Pingyang small piece,Fenhe part of Zhong Yuan Mandarin.Guxian dialect is extremely complicated.Through the analysis of the continuous reading materials,it can be seen that there is a history of "Zhuo shang gui qu" in the dialect of Guxian(Yaodian)dialect,following the law of "Qu fen yin and yang".At the same time,through the fieldwork materials,it can be found that there is a tendency of "Shang qu he liu " in the dialect of the Guxian(Yaodian)dialect.That is,thesingle-character tones is a merged one,and the continuous tone is a difference.According to the reasons of confluence,this thesis analyzes from some angles: similar value adjustment,full turbid air supply,continuous curing,common language interference and peripheral dialect influence.In addition,existing researches have shown that the Huozhou dialect in the north of Yaodian,the western Hongdong dialect,the Linfen dialect,the southern Fushan dialect,and the Yicheng dialect all have five single-character tones,and the falling tone is divided into yin and yang,(although it is not founded in Linfen District’s dialect,but commons in dialects of surrounding cities and counties and subordinate townships.The eastern county township dialect has only three single-character tones and has not the falling tone.That is to say,the Guxian(Yaodian)dialect is surrounded by the dialects of the five-character tones and the three-character tones.There is only one falling tone in the single-character tones,which belongs to the dialect of the four-character tones.In other words,in the Pingyang small piece dialect of Fenhe part of Zhong Yuan Mandarin,there is one tone gradient chain,starting from the cities and counties around Linyi,ending uo with the Guxian county dialect.Through this tone gradient chain,we can predict the future development trend of the Pingyang small piece dialect tone.
