| 中文摘要: |
| 通过实地调查和查阅文献资料,对南涧凤凰山州级自然保护区野生种子植物组成和分布区类
型进行分析,并与邻近地区5个自然保护区进行比较,分析凤凰山植物区系特征。结果表明,保护
区内共有野生种子植物97科266属389种,科的组成以小科、极小科为主,科内种的组成以较大
科、中等科为主;属的组成、属内种的组成均以小属、极小属为主。区系地理成分复杂,联系广泛,属
含17个分布区类型及变型,种含21个分布区类型及变型。温带性质明显,温带分布的属占比
55.41%,温带分布的种占比64.34%。凤凰山种子植物区系R/T值与太极顶最为接近,与水目山差距
最大;种系分化程度与大龙潭、巍宝山最为接近;亲缘关系与大龙潭、巍宝山最近,与水目山最远。 |
| 英文摘要: |
| Through field surveys and literature review, this study analyzed the composition and distribution
types of wild seed plants in Nanjian Fenghuangshan Nature Reserve. A comparison was made with
five nearby nature reserves to examine the floristic characteristics of Fenghuangshan. The results showed
that the reserve harbors 389 species of wild seed plants, belonging to 266 genera and 97 families. The
family composition is dominated by small and very small families, while the species composition within
families is mainly represented by relatively large and medium-sized families. Both the genus composition
and species composition within genera are predominantly small and very small genera. The floristic geographical
elements are complex and widely connected, with genera covering 17 distribution types and variants,
and species comprising 21 distribution types and variants. The temperate characteristics are prominent,
with temperate-distributed genera accounting for 55. 41% and temperate-distributed species
making up 64. 34%. The R/ T value of the seed plant flora in Fenghuangshan is most similar to that in
Taijiding, and shows the greatest difference from Shuimushan. The degree of species differentiation is most similar to that of Dalongtan and Weibaoshan, while its floristic affinity is closest to Dalongtan and
Weibaoshan and most distant from Shuimushan. |
