后河自然保护区野生保护植物优先保护定量研究

笔者在野外调查和查阅文献资料的基础上,研究了湖北五峰后河自然保护区国家重点保护野生植物的分布情况,并运用濒危系数、遗传价值系数和物种价值系数对其优先保护顺序进行了定量分析.结果表明:①后河自然保护区共有国家重点保护野生植物25种,其中Ⅰ级7种,Ⅱ级18种,分别占湖北省分布的54.4%、87.5%和47.4%;②采用优先...

Quantitative Study on Priority for Conservation of The Wild Protected Plants In Houhe National Nature Reserve

Based on the field investigation and looking up reference,the distribution of the national key protected wild plants in Houhe Nature Reserve was studied and analyzed by authors,and the priority conservation of the national key protected wild plants was quantitative analyzed by using the threatened coefficient,the genetic coefficient and the species value coefficient.The results showed that① There were 25 species of the national key protected wild plants in Houhe Nature Reserve,among which 7 species belonged to the first class,18 belonged to the second class,and each accounted for 54.4 %,87.5 % and 47.3 % in Hubei province respectively;② 25 species of the national key protected wild plants were sequenced by the system of priority conservation and evaluation,and the results were different from The checklist of national key protected wild plants（the first passel）5 species belonged to the first rank reserve,and accounted for 20%,16 species belonged to the second rank reserve,and accounted for 64%,4 species belonged to the third rank reserve,and accounted for 16%.③Plant threatened status and priority preservation sequence were more truly reflected by the evaluation and rating results from this evaluation system.Therefore it is very significant for the priority conservation of the national protected plants in this area.
