摘要:

【目的】确定江西武夷山国家级自然保护区珍稀濒危植物真实的受威胁状态以及优先保护顺序,为保护区制定珍稀濒危植物保护策略提供参考依据。【方法】采用样线法并结合历史文献资料,运用濒危系数、遗传价值系数和物种价值系数定量分析江西武夷山保护区113种珍稀濒危野生植物优先保护顺序,并结合Sorensen相似性系数比较保护区与福建武夷山、浙江天目山、江西庐山、湖北万朝山、重庆金佛山等5个邻近地区珍稀濒危植物的关系。【结果】①江西武夷山国家级自然保护区共有47科85属113种珍稀濒危植物,其中国家一级保护植物6种,二级保护植物15种;江西省Ⅰ级保护植物20种,Ⅱ级保护植物11种,Ⅲ级保护植物55种,江西特有植物12种。②根据优先保护定量分析,被划定为Ⅰ级优先保护的有17种,占物种总数的15.04%;Ⅱ级优先保护41种,占36.28%;Ⅲ级优先保护54种,占47.79%;Ⅳ级优先保护仅1种,占0.89%。③江西武夷山与邻近5个地区的相似性系数均在30%左右,但拥有更多的珍稀濒危植物种类(38种)和较高的单位面积物种比例(0.24),表明其具有更高的保护价值。【结论】江西武夷山生境良好,珍稀濒危植物种类多,具有较高的生态保护价值。本研究建立的评价体系对江西武夷山113种珍稀濒危植物的评价与分级结果更真实地反映了其在保护区的现状,评估结果可为保护区对受威胁物种制定有针对性的有效保护方案提供参考依据。

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.
