摘要
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化龙山自然保护区 1 6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香果树、青檀、大果青杆、厚朴和山白树 5种 ,属二级保护的有延龄草、鹅掌楸、紫茎、水青树、麦吊云杉和秦岭冷杉 6种 ,属三级保护的有黄杉、杜仲、华榛和黄莲 4种 ,属四级保护的有狭叶瓶尔小草 1种。
Based on field investigation,the coefficient of endangerment,the coefficient of lost genetic diversity and the coefficient of value are used for quantitative analysis to determine the priority of conservation of the national protected plants distributed in Hualongshan Mountain nature preserve.The studied results show that of the 16 national protected plants,5 plants belong to the first class protection,6 to the second,4 to the third,and 1 to the fourth.Some effective conservational measures have been put forward.
