湖北赛武当自然保护区野生珍稀植物优先保护定量研究

Quantitative study on priority conservation of wild rare plants in Saiwudang National Nature Reserve, Hubei

  • 摘要: 通过对湖北赛武当国家级自然保护区内的野生珍稀植物资源进行调查,运用濒危系数、遗传价值系数和物种价值系数,计算出物种优先保护值,以确定物种濒危等级和优先保护等级。结果显示:(1)该区内共有珍稀保护植物33种,隶属于26科33属,其中易危15种、近危11种、安全种7种;(2)该区珍稀植物优先保护值的范围为0.2631~0.6985,据此得出33种珍稀植物的优先保护等级为:Ⅰ级6种、Ⅱ级13种、Ⅲ级12种、Ⅳ级2种。(3)本研究结果与相关珍稀保护植物名录的濒危等级和优先保护级别存在较大差异,这可能是由于生境破碎化和人为干扰导致大部分植物在本区受威胁程度加重,因此应强化管理。

     

    Abstract: We quantitatively investigated wild rare plant resources in Saiwudang National Nature Reserve, Hubei Province, China. The priority conservation of rare plants was analyzed using the threatened coefficient, genetic coefficient, and species value coefficient. The endangerment and conservation priority levels were then determined. Results showed that:(1) There were 33 species of rare plants belonging to 33 genera and 26 families, including 15 vulnerable species, 11 near threatened species, and seven safe species; (2) The priority conservation values of these species ranged from 0.2631 to 0.6985. Accordingly, six species were ranked as first grade, 13 species were ranked as second grade, 12 species were ranked as third grade, and two species were ranked as fourth grade conservation priority; (3) The endangerment and conservation priority levels varied significantly between our research and rare plant lists. These differences may result from habitat fragmentation and human disturbance, which severely threaten most plants in this area. Therefore, it is essential that the management of these rare and endangered plants is intensified.
