The comparative study of dwelling houses in the southwest multi-ethnic region, taking Fugong county for

Fang WANG, Jiaping LIU

Frontiers of Structural and Civil Engineering 2010, Volume 4, Issue 4,   Pages 474-482 doi: 10.1007/s11709-010-0089-z

Abstract: A number of ethnic minorities are being distributed in southwest China. Yunnan Province is an area inhabited by multi-ethnic groups. For a long time, the ethnic groups have been interacted by others in the cultural aspect, while retaining their own ethnic traditions. The performances of ethnic groups’ dwelling houses are similar as determined by natural and cultural elements of the same area. This paper mainly analyzes decisive factors behind similar appearances by the way of field research on two minorities, Nu ethnic group and Li-su ethnic group, in the Fugong county, Nujiang Li-su autonomous prefecture. Moreover, the paper tries to summarize the commonality and individuality of the minorities in order to provide useful theoretical reference for the minorities building of new socialist countryside in the future.
