Flora of seed plants in Qinghai Area of the Kunlun Mountain National Park
[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.
