摘 要:依据2021版《国家重点保护野生植物名录》和《陕西省分布的国家重点保护野生植物名录》,对陕西省分布的国家重点保护野生植物资源和保护现状开展了调查研究。结果表明:(1)国家重点保护野生植物共38科67属104种(含种下等级),含石松类1科1属3种,占总数的2.88%;裸子植物2科6属6种2变种,占6.73%;被子植物35科60属85种1亚种10变种,占比高达90.38%。(2)保护植物约占全省维管植物科的18.18%、属的5.09%、种的2.00%,秦岭石蝴蝶、长柱玄参为陕西特有种。(3)新名录保留1999版国家重点保护植物26种,新增78种,含原陕西省地方重点保护植物24种,象鼻兰、曲茎石斛、紫斑牡丹等原无保护级别直接列入的共54种,占全省分布的国家重点保护植物总数的52%;濒危等级分析显示,极危(CR)占4.81%、濒危(EN)和易危(VU)各占24.04%。(4)国家级重点保护植物在陕西省呈现出南多北少的分布特征,镇坪县多达60种(占全省保护植物的57.69%),平利县和佛坪县各有47种。(5)全省各级自然保护区、湿地公园、森林公园等共有249个,在保护区内有分布的保护植物约70种,占总数的67.31%。建议开展新增物种,尤其是对原来无保护级别的54种的资源和分布进行调查与研究,更新自然保护区的保护植物信息且进行动态监测,加大陕西省黄土高原区域植物园建设,为就地保护和迁地保护等提供科学基础。Based on the references of natural reserves in Shaanxi Province,field survey,and digitized herbarium specimens provided by China Virtual Herbarium(CVH),and List of National Key Protected wild Peauts(NKPWPs)(2021 Version),and List of National Key Protected Wild Plants distributed in Shaanxi Province.The resource and conservation status of species NKPWPs distributed in Shaanxi Province was investigated and analyzed in present study.The results were as follows:(1)A total of 104 species(including subspecies and variety)belonged to 38 families,67 genera were distributed in Shaanxi Province,including 3 species in 1 genus of 1 family of lycophytes,6 species and 2 varieties in 6 genera of 2 families of gymnosperms,and 85 species,1 subspecies and 10 varieties in 60 genera of 35 families of angiosperms,representing 2.88%,6.73% and 90.38% of the total NKPWPs,respectively.(2)The number of the NKPWPs represented about 18.18%,5.09%,and 2% of families,genera and species of the total vascular plant in Shaanxi Province,respectively.(3)Among 104 species of NKPWPs,26 species listed in the last version(1999)had been protected,and 78 species were added newly,in which 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 were critically endangered(CR),representing 4.81%,22 species were endangered(EN)and 22 species were vulnerable(VU),representing 24.04% of the total NKPWPs,respectively.(4)Qinling-Bashan region was a concentrated distribution area of NKPWPs,about 60 species were distributed in Zhenping County,accounting for 57.69% of the total,and 47 species were distributed in both Pingli County and Foping County;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),wet
