摘　　要：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鄂东大别山18种国家重点保护野生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、南方红豆杉、大别山五针松、金钱松、巴山榧树、连香树和楠木共7种,占38.9%;属二级保护的有秤锤树、喜树、香果树、鹅掌楸和川黄檗共5种,占27.8%;属三级保护的有厚朴、凹叶厚朴和榉树3种,占16.7%;属四级保护的有樟树、野大豆和金荞麦共3种,占16.7%。并提出了加强国家重点保护野生植物的保护措施。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 Dabieshan in this paper. The results showed that 7 species of the national protected plants belong to the first class protection,occupying 38.9% of total,5 species belong to the second,occupying 27.8% of total,3 species belong to the third,occupying 16.7% of total, and 3 species belong to the fourth ,occupying 16.7% of total. Some effective conversation measures have been put forward.
