Linguistic Dynamism of Tibeto-Burman Languages in China-Laos-Myanmar Border Area

本研究项目通过田野调查，对中老缅边境地区的藏缅语进行了描述，并对该地区人民的交往史和民族迁徙史进行了考察。在此期间，我对基诺族（中国云南）、阿卡族（中国云南）、西达族（老挝琅南塔）和普诺伊族（老挝琅南塔）的语言进行了语言学田野调查。 本课题首先梳理了基诺族语两种方言的历史发展，并根据笔者的田野调查，简要地认为基诺族布源方言与阿卡的格朗河方言在词汇上有相似之处，而基诺族尤勒方言与思达语在很多方面有相似之处。可以推测，思达人可能是从基诺族分化出来后从中国迁移到老挝的，但还需要进一步分析。

This research project describes Tibeto-Burman languages spoken in the area surrounding China-Laos-Myanmar border through fieldwork and investigates the history of contacts among the people in this area and that of ethnic migration. During this research period I carried out linguistic fieldwork on the languages of Jino (Yunnan, China), Akha (Yunnan, China), Sida (Luang Namtha, Laos) and Phunoi (Luang Namtha, Laos). This project clarified the historical development of both dialects of the Jino language.And from the field work I conducted, I briefly consider that the Buyuan dialect of Jino is similar to the Gelanghe dialect of Akha from the lexical viewpoints and the Youle dialect of Jino is similar to the Sida language in many respects. It can be assumed that the Sida people might have migrated from China into Laos after diverge from the Jino ethnic group, though it needs further analyses.
