基于野外调查和文献资料数据整合，形成了陕西特有维管植物名录，并对陕西特有维管植物物种组成特征、区系成分以及分布格局进行了分析。结果表明：陕西特有维管植物有134种(包含种下等级，下同)，归属于41科76属，占陕西维管植物总种数的2.6%；其中，特有种子植物133种，占陕西种子植物总种数的2.7%，包括特有被子植物132种、特有裸子植物1种；特有蕨类植物仅1种，占陕西松类和蕨类植物总种数的0.4%；无陕西特有属。从生活型看，陕西特有维管植物中多年生草本占绝对优势(占比61.9%)，灌木和乔木种数较多(占比分别为16.4%和11.2%)。种数最多的科为菊科(Asteraceae)，达18种（占比13.4%）；种数最多的属为柳属(Salix Linn.)，达10种（占比7.5%）。陕西特有种子植物科和属的区系成分中，北温带分布型及其变型均最多（占比分别为43.5%和49.2%）。在水平维度上，从北到南特有维管植物种类呈现骤增后骤减的趋势；在垂直维度上，特有维管植物主要集中分布在1 000～3 000 m的中高海拔区间，且物种丰富度随海拔升高呈现“升—降—升—降”趋势。综上所述，陕西维管植物特有性低，特有种子植物区系具有明显的温带性质，且特有维管植物的空间分布格局极不均衡。

 Based on the integration of field surveys and literature data, a checklist of vascular plants endemic to Shaanxi was compiled, and the species composition characteristics, floristic elements, and distribution patterns of vascular plants endemic to Shaanxi were analyzed. The results show that there are 134 species (including infraspecific taxa, the same below) of vascular plants endemic to Shaanxi, belonging to 76 genera of 41 families, accounting for 2.6% of total species number of the vascular plants in Shaanxi; among them, 133 species are endemic seed plants, accounting for 2.7% of total species number of the seed plants in Shaanxi, including 132 species of endemic angiosperms and  1 species of endemic gymnosperm; there is only 1 species of endemic fern, accounting for 0.4% of total species number of the lycophytes and ferns in Shaanxi; no genus is endemic to Shaanxi. In terms of life forms, perennial herbs are absolutely dominant (accounting for 61.9%) in vascular plants endemic to Shaanxi, while shrubs and trees have a relatively large number of species (accounting for 16.4% and 11.2%, respectively). The family with the largest number of species is Asteraceae, with 18 species (accounting for 13.4%); the genus with the largest number of species is Salix Linn., with 10 species (accounting for 7.5%). Among the floristic elements of families and genera of seed plants endemic to Shaanxi, the N. Temp. areal-type and its varieties are the most  (accounting for 43.5% and 49.2%, respectively). Horizontally, endemic vascular plant species show a sharp increase followed by a sharp decrease from north to south; vertically, they are mainly concentrated in the mid- to high-altitude range of 1 000-3 000 m, with species richness showing a trend of “increase-decrease-increase-decrease” with the increase of altitude. In conclusion, the vascular plants in Shaanxi have low endemism, the endemic seed plant flora possesses obvious temperate characteristics, and the spatial distribution patterns of endemic vascular plants are extremely uneven.
