Abstract: The Gan-Qing area known as the "Northwest Ethnic Corridor" of China is always a stage of multi-ethnic existence,
development and blending. Combining the two factors of lineage and minority identity, the article attempts to divide the lineage in the
Northwest Ethnic Corridor into three types: the lineage of multi-ethnic identity, of changing identity and of continuing identity, and
then takes the three types as an example to study the rules and characteristics of the lineage identity in the Northwest National Corridor.

Key words: Northwest Ethnic Corridor of China, lineage, identity
