Abstract: Postcolonialist Homi K.Bhabha explores the “hybridity” theory in the location of culture，taking it as an effective way to eliminate cultural dominance and opposition in post colonialism language context.The phenomenon of hybridity is also showed in the following two aspects of Langston Hughes′s poetry：the hybridity of the poet′s cultural identity and the hybridity of some of his poems.This similarity demonstrates that when exploring the development of the minority culture，both Homi K.Bhabha and Langston Hughes encourage the deconstruction of mono-culture and the equal，harmonious coexistence of various cultures.

Key words: poetry, Homi K.Bhabha, hybridity, Langston Hughes, African-American literature, ethnic culture, plural culture
