[ Objective ] From the aspect of species representativeness and diversity , the article aims to pro- vide evidence for plant diversity conservation and plant resource utilization in Qinghai area of the Kunlun Mountain National Park. [ Methods ] Based on field surveys , historical data , and literatures , we sorted out a list of seed plants in the assessment area and analyzed the composition , dominant taxa , geographic com- ponent , and endangered species of seed flora. [ Results ] ( 1 ) There was a total of 46 families , 146 genera , and 384 species of seed plants in Qinghai area of the Kunlun Mountain National Park , including 3 families , 3 genera , and 5 species of gymnosperms as well as 43 families , 143 genera , and 379 species of angio- sperms. The 4 families included Amaranthaceae , Asteraceae , Fabaceae and Poaceae occupy an important position in the seed flora of the assessed area , where monospecie and oligospecie constitute the main part of the family. ( 2 ) The dominant phenomenon of the seed plant family and genus was obvious in this area with 8 dominant families and 36 dominant genera , where 6 large genera had more than 10 species including Astragalus , Oxytropis , Artemisia , Saussurea , Poa , and Carex . ( 3 ) The areal-type of the families in this seed flora was mainly cosmopolitan , which was showing a temperate nature. The areal-type of genera was mainly temperate distribution with a close connection to the Laurasia. ( 4 ) There were 4 species of na- tional Grade Ⅱ protected wild plants , 8 species of Qinghai Province protected plants , and 6 species listed in “ China􀆴s Red List of Biodiversity ” . [ Conclusion ] The Qinghai area of the Kunlun National Park has di- verse geographical composition , but the endemic phenomenon is not obvious. The biodiversity is low. The floral composition shows the characteristics of arid to semi-arid transition and temperate to tropical transi- tion in the horizontal gradient.
