福建分布的中国种子植物特有属研究

On the Genera of Spermatophyte Endemic to China in Fujian Region

探讨了福建地区中国种子植物特有属的科、属组成,区系性质,生活型构成及其地理分布格局.结果表明:福建分布的中国种子植物特有属共有43属,55种,分属于32科,其中仅有1属为福建地方特有属,含特有属较多的科为苦苣苔科和唇形科.在福建分布的中国种子植物特有属具有单、少种特有属比例大、木本属数量占优势、古老特有残遗属居多等特点,闽北武夷山地区是中国种子植物特有属在福建的分布中心,丰富的特有属也反映出福建种子植物区系的多样性.

This paper deals with the study of Chinese endemic genera of seed plants and the geographical distribution of families and genera in Fujian. The result showed that the distribution of the Fujian Chinese endemic genera of seed plants was 43 genera, with a total of 55 species, be- longing to 32 families, among them there was only one endemic genus found in Fujian. The families Gesneriaceae and Labiatae contain the most endemic genera. In Fujian the distribution of Chinese endemic genera of seed plants have a large proportion of monotypic and oligotypic, a number of dominant woody plants, and a majority of ancient unique residual survivor. Wuyi mountain and northern Fujian area is the distribution center of the endemic genera of seed plants, and the rich en- demic genera also reflect the floral diversity in Fujian.
