Abstract： Based on the references of natural reserves in Shaanxi P rovince field survey, and digitized herbarium specimens provided by China V irtual Herbarium (CVH), the resource and conservation status of species listed in national key protected wild plants ( (2021 version ) distributed in Shaanxi Province was investigated and analyzed in present study, and it can provide a scientific basis for future research on in situ and ex situ conservation . The results were as follows : (1) A total of 104 species (including subspecies and variety) were belonged to 38 families, 67 genera were distributed in Shaanxi province, including 3 species of Lycophytes, 6 species and 2 varieties of Gymnosperms, and 85 species, 1 subspecies and 10 varieties of Angiosperms, representing 2.88%, 6.73% and 90.38% of the total NKPWPs respectively. (2) The number of the NKPWPs represent ed about 18.18%, 5.09%, and 2% of families, genera and species respectively of the total vascular plant in Shaanxi P rovince . (3) Among 104 species of NKPWPs , 26 species listed in the last version (1999) ha d been protected , and 24 species were ever listed and protected as local protected wild plants , and a total of 54 additional species were not protected at all before, accounting for 52% of the total NKPWPs, e.g. Phalaenopsis zhejiangensis, Dendrobium flexicaule and Paeonia rockii. The endangered status analysis showed that 5 species are Critically Endangered (CR), representing 4.81%, 22 species were Endangered (EN) and 22 were Vulnerable (VU), representing 24.04% of the total NKPWPsNKPWPs. (4) Qinling-Bashan region was a concentrated distribution area of NKPWPsNKPWPs, about 60 species were distributed in Zhenping County, accounting for 57.69% of the total, and 47 species were distributed in both Pingli and Foping counties; contrast to it, few species found in the north area of Shaanxi Province. (5) There were 249 reserves in Shaanxi Province, including the natural reserve (national and provincial), wetland parks and forest parks, and about 70 species representing 67.31% of NKPWPs had been effectively protected in these areas. We suggest: (1) investigate the resources, distribution and status of the additional species of NKPWPs in Shaanxi Province Province, especially focus on the 54 species which are not previously protected; (2) facilitate the regional botanical gardens in the Loess Plateau area of Shaanxi Province; (3) dynamic monitor and update data of NKPWPs in natural reserves, so as to provide a scientific and valuable reference for in situ and ex situ conservation in the future.
