濒危植物凹叶木兰(Magnolia sargentiana)栖息地维管植物多样性研究

A Study of Plant Diversity in the Habitat of Endangered plant Magnolia sargentiana

  • 摘要: 濒危植物凹叶木兰为我国特有种。2006年对四川和云南两地野生凹叶木兰栖息地进行了详细的调查。结果表明,凹叶木兰栖息地共有维管植物104科233属379种。其中,蕨类植物有17科26属39种,种子植物87科207属340种。通过对凹叶木兰栖息地种子植物的调查及其科、属的分布区类型分析的结果表明:其栖息地种子植物区系成分较为复杂、种类丰富,起源古老且具温带性质,植物区系过渡性明显。凹叶木兰仅分布于四川和云南少数地区,分布区较为狭窄。

     

    Abstract: Endangered plant Magnolia sargentiana is Chinese endemic species. In the year 2006,investigations were made on the habitats of wild Magnolia sargentiana in Sichuan and Yunnan provinces. It was found that there were 379 species of vascular plants,belonging to 104 families, and 233 genera, of which 17 families,26 genera and 39 species were ferns, meanwhile 87 families, 207 genera, and 340 species were seed plants. Besides analysis was made of the distribution types of families and genera of seed plants in the habitat of Magnolia sargentiana. The results showed that flora of seed plants in the habitat of Magnolia sargentiana was complex and abundant. The their origin was ancient and belonged to temperate zone,but the transitivity of flora was remarkable. Magnolia sargentiana had a limited distribution,and was only distributed in some areas of Sichuan and Yunnan provinces. The study of the habitat of Magnolia sargentiana would provide an important basis for its conservation.
