摘要
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采用优先保护评价体系对25种国家重点保护野生植物进行排序,其结果与《国家重点保护野生植物名录(第一批)》结果有所不同,属Ⅰ级保护的有5种,占总数的20.0%;属Ⅱ级保护的有16种,占总数的64.0%;属Ⅲ级保护的有4种,占总数的16.0%。③该评价体系对25种植物的评价与分级结果更真实地反映了它们在后河保护区受威胁状态和优先保护顺序,对该区重点保护野生植物的优先保护工作具有一定指导意义。
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.
