Language contact always causes the language evolution. Because Monguor people have a long period of language contact with Chinese, the Minhe dialect of Monguor language has been strongly affected by Chinese, resulting in a host of unique phonetic, vocabulary and grammatical evolution phenomena. But this situation cannot change the essential characteristics of language, Monguor language is still used as an effective communication tool for the nation. Minhe dialect is a dialect strongly affected by Chinese, and has entered a quite similar stage with Chinese. The contact between Min dialect and Chinese is a special type of various language contact. Its basic contact mode is the mode of coexistence, competition, weakening, convergence of inherent components and borrowing elements. From the perspective of language contact, the formation of these characteristics have a direct relation with the situation that the native people are closely related to Han nationality and strongly affected by Chinese. This paper mainly studies the language evolution of Minhe dialect caused by the influence of Chinese through the synchronic analysis of the Minhe dialect and the comparison with the Huzhu dialect. The analysis of the characteristics of Minhe dialect, especially the language variation caused by the influence of Chinese, is of theoretical value to the study of language contact.
