Conservation status and prioritization of rare and endangered plants in Jiangxi Wuyishan National Nature Reserve
摘要
Abstract
[Objective]This research aims to determine the actual threat level and prioritize the conservation of rare and endangered plants in the Wuyishan National Nature Reserve in Jiangxi Province,provide a reference for the conservation of these plants in the nature reserve.[Method]Using the line transect method combined with historical literature,the endangered coefficient,genetic value coefficient,and species value coefficient were used to quantitatively analyze the conservation priorities of 113 rare and endangered wild plants in the Wuyishan National Nature Reserve in Jiangxi Province.The relationship between the rare and endangered plants of Wuyishan in Jiangxi Province and five adjacent areas,namely Wuyishan in Fujian Province,Tianmushan in Zhejiang Province,Lushan in Jiangxi Province,Wanchaoshan in Hubei Province,and Jinfoshan in Chongqing City,were compared using the Sorensen similarity coefficient.[Result](1)There were 113 species of rare and endangered plants in the reserve,belonging to 47 families and 85 genera.Among these,there were 6 species classified as National Class Ⅰ,15 species as National Class Ⅱ.20 species were classified as Jiangxi Province Class Ⅰ,11 species as Jiangxi Province Class Ⅱ,55 species as Jiangxi Province Class Ⅲ,and 12 species endemic to Jiangxi.(2)According to the quantitative analysis of conservation priority,17 species(15.04%)were assessed as first class,41 species(36.28%)as second class,54 species(47.79%)as third class,and 1 species(0.89%)as fourth class.(3)The similarity coefficient between Wuyishan in Jiangxi Province and the five adjacent areas were about 30%.However,Wuyishan in Jiangxi Province owned more rare and endangered plants(38 species)and a higher proportion of species per unit area(0.24),indicated a higher conservation value.[Conclusion]The excellent habitats and abundant rare and endangered plants in Wuyishan in Jiangxi Province indicate a high conservation value.The assessment and classification of the 113 rare and endangered plants more accurately reflect their current situation in the Nature Reserve,providing a reference for effective conservation plans for threatened species.关键词
