太白山特有珍稀植物优先保护顺序的定量分析

A quantitative analysis on priority of conservation of endemic and rare 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 5种特有珍稀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秦岭乌头、太白山黄芪、陕西鹅耳枥和太白美花草 4种 ,属二级保护的有秦岭蔷薇、秦岭花楸、太白扬、玉兰、假百合和秦岭党参 6种 ,属三级保护的有太白贝母、铁筷子、长果升麻、反萼银莲花和手参 5种。提出了加强太白山特有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 species value were used for quantitative analysis to determine the priority of conservation of the endemic and rare p1ants distributed in Taibai Mountain Nature Preserve.The studied results showed that of the 15 endemic and rare plants,4 belong to the first class protection, 6 to the second, and 5 to the third. Some effective conservational measures have been put forward.
