In this paper, we use Tibetan Lhasa Dialect phonological system as research object, analyzed and studied the structure and distribution of phonological, and it shows that each phoneme of Tibetan in a system have their own position which can better quantitative description and reflect essence and variety of the synchronic and diachronic of language.
