星斗山国家级自然保护区国家重点保护野生植物优先保护定量研究

在野外调查的基础上,运用濒危系数、遗传价值系数和物种价值系数对星斗山自然保护区33种国家保护植物的优先保护顺序进行定量分析。结果表明属一级保护的有银杏、水杉、伯乐树、珙桐、光叶珙桐、台湾杉和水青树共7种,占21%;属二级保护的有红豆杉、南方红豆杉、蓖子三尖杉、大果青杄、金钱松、黄杉、榧树、连香树、闽楠、楠木、花榈木、鹅掌楸、峨眉含笑、红椿、毛红椿和川黄檗共16种,占49%;属三级保护的有莼菜、金毛狗、红豆树、厚朴、凹叶厚朴、香果树和榉树7种,占21%;属四级保护的有樟树、野大豆和金荞麦共3种,占9%。并提出了加强重点保护野生植物的保护措施。

Quantitative assessment of hriority for conservation of the national protected plants in Xingdoushan Nature Preserve

Based on field investigation,the threatened coefficient,the genetic coefficient and the specific value coefficient were used for quantitative analyses to determine the priority of conservation of the national protected plants distributed in Xingdoushan Nature Preserve. The results showed that 7 species of the national protected plants belong to the first class protection,consisting 21% of total,16 species belong to the second,consisting 49% of total,7 species belong to the third, consisting 21 % of total,and 3species belong to the fourth,consisting 9% of total. Some effective conversation measures have been provided.
