摘要
通过对佛顶山国家级自然保护区重点保护植物系统性调查,运用濒危系数、遗传价值系数、生境型系数、保护等级系数及利用价值系数5个指标,分配不同的权重综合计算出保护区内国家重点保护植物优先保护值,确定物种的濒危等级与优先保护等级,结果表明:(1)保护区内共有国家重点保护植物15种,隶属13科13属,国家Ⅰ级保护植物4种,国家Ⅱ级保护植物11种;(2)保护区内重点保护植物优先保护值的范围为0.454~0.720,得出该保护区内重点野生保护植物的优先保护等级为:Ⅰ级6种、Ⅱ级8种、Ⅲ级4种、Ⅳ级0种;(3)在空间分布上以九茶树、万佛山、二道堰等地为集中分布区,以1050~1450 m为垂直集中分布区,多种树种处在保护区核心区和缓冲区,实行了严格管理,得到了有效保护,部分树种处在实验区或保护区外围区,受到较为频繁的干扰,应适当进行功能区优化调整并加强管理。
Through the systematic investigation of the key protected plants in the National Nature Reserve of Fodingshan,five indicators including the endangered coefficient,the genetic value coefficient,the habitat type coefficient,the protection grade coefficient and the utilization value coefficient were used for comprehensive calculation by assigning different weights.The priority protection value of the national key protected plants in the protected area was used to determine the endangered level and priority protection level of the species.The results showed that:(1)There were 15 species of national key protected plants in the protected area,belonging to 13 families and 13 genera,of which 4 species of national grade I protected plants,11 species of national grade II protected plants;(2)The priority protection value of key protected plants in the reserve was 0.454-0.720,and the priority protection level of key wild protected plants in the reserve was:6 species of grade I,8 species of grade II,4 species of grade III,and 0 species of grade IV;(3)In the spatial distribution,Jiuchashu,Wanfoshan,Erdaoyan and other places were the concentrated distribution areas,with the vertical concentrated distribution area of 1050-1450 m.A variety of tree species were located in the core area and buffer zone of the protected area,which had been strictly managed and effectively protected.Some tree species were located in the experimental area or the peripheral area of the reserve,which were frequently disturbed.Therefore,it is necessary to optimize and adjust the functional area and strengthen the management.
