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 2 3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、星叶草、杜仲、桃儿七、连香树、大果青木千、青檀、紫斑牡丹 9种 ,属二级保护的有水青树、金钱槭、山白树、水曲柳、秦岭冷杉、领春木、羽叶丁香 7种 ,属三级保护的有野大豆、膜荚黄芪、华榛、延龄草、庙台槭、天麻 6种 ,属四级保护的仅狭叶瓶尔小草 1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 23 national protected plnnts,9 belongs to the first class protection,7 to the second , 6 to the third and 1 to the fourth .Some effective conservational measures have been put forward.
