Qinghai-Tibetan Plateau is a global biodiversity hotspot due to the unique geographical environment. However, there are few reports on the list of national key protected plants and the distribution pattern of their diversity in this area. Based on the flora and online database, this paper summarised the species diversity and distribution patterns of national key protected wild plants on the Qinghai-Tibet Plateau.
The results showed that there were 350 species of national key protected wild plants on the Qinghai-Tibetan Plateau, belonging to 72 families and 130 genera. Amongst them, 22 species were under class I protection, 328 species were under class II protection and 168 species were endemic to China. Its endangered status involves EW 1 species, CR 17 species, EN 90 species, VU 90 species, NT 30 species, LC 60 species and DD 62 species. Species diversity declined gradually from the southeast to the northwest with hotspots located within Sanjiang Valley subregion (ⅢE14a). The list of national key protected wild plants and their diversity and distribution patterns in the Qinghai-Tibetan Plateau can provide basic data for the conservation of regional biodiversity and the formulation of conservation strategies.
由于独特的地理环境，青藏高原是全球生物多样性热点地区。然而，关于该地区国家重点保护植物名录及其多样性分布格局的报道较少。基于植物区系和在线数据库，本文总结了青藏高原国家重点保护野生植物的物种多样性和分布格局。
结果表明，青藏高原共有国家重点保护野生植物350种，隶属于72科130属。其中，一级保护植物22种，二级保护植物328种，中国特有植物168种。其濒危状况涉及极危（EW）1种、濒危（CR）17种、易危（EN）90种、近危（VU）90种、无危（NT）30种、低关注度（LC）60种和数据缺乏（DD）62种。物种多样性从东南向西北逐渐降低，热点区域位于三江谷地亚区域（ⅢE14a）。青藏高原国家重点保护野生植物名录及其多样性和分布格局可为区域生物多样性保护和保护策略的制定提供基础数据。
