太白山国家保护植物优先保护顺序的定量分析

A quantitative analysis on priority of conservation of the national protected plants in Taibai Mountain

在野外调查的基础上 ,运用濒危系数、遗传多样性损失系数和物种价值系数对太白山自然保护区1 1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太白红杉、独叶草、杜仲、桃儿七、连香树 5种 ,属二级保护的有水青树、秦岭冷杉、领春木 3种 ,属三级保护的有延龄草、庙台槭、天麻 3种 .提出了加强珍稀植物保护的措施 .

Based on field investigation,the coefficient of endangerment, the coefficient of lost genetic diversity and the coefficient of value were used for quantitative analyses to determine the priority of conservation of the national protected plants distributed in Taibai Mountain Nature Preserve in this paper.The studied results showed that of the 11 national protected plants, 5 belongs to the first class protection, 3 to the second and 3 to the third.Some effective conservational measures have been put forward.
