The research on plant resources of Qiangtang Plateau and upper area of Yarlungzangbo River were relatively scant until now. We investigated their vegetation, collected plant germplasm resources, and then evaluated their resource amount. The results showed that specimen and germplasm collected include 148 species belonging to 90 genera and 31 families, in which Compositae, Graminae, Cyperaceae and Leguminosae were dominant. Most of flora elements of families are worldwide distribution and flora elements of those genus showed temperate characteristics. Endemic species and Central Asian distribution and their varieties are in absolute dormancy and these reflected lots of emerged endemic species because of the QinghaiXizang Plateau uplift, and indicated close relationship with Central Asian distribution flora. The vegetation traits was described there, the exploitation and utility were valuated on local special economic plants such as Oxytropis glacialis, Oxytropis falcate, Morina kokonorica and so on. At last, the authors give some related suggestion about conserving and reasonably making use of those plant resource.
